AGENDA


 Top VMworld 2011 myths

 Storage Design and Architecture for vSphere
  ‒ VMware and Hitachi integration
  ‒ Hitachi AMS2000 and Virtual Storage Platform formula
  ‒   VMware storage APIs - VASA and VAAI
Myth #1
It makes more sense to deploy vSphere 5 over NFS
WHY NAS? (ADVANTAGES)


 Flexibility and Cost Savings
  ‒ vSphere supports iSCSI, FC, FCoE and NFS (IP)
  ‒ All functionality of vSphere can be exploited over NFS with a few
    exceptions
       ‒ Cannot cluster VMs using Microsoft Cluster Server
       ‒ Cannot boot the Physical host directly from NFS (requires some internal disk)
       ‒ No true multi-path I/O Engine (although network can provide fault tolerance)

  ‒ NFS/IP Ethernet perceived as less costly, less complex and more
    flexible in deployment
  ‒ NFS provides a level of virtualization that enables it to abstract
    some physical level constraints – simple provisioning, LUN queue
    mgmt, VMFS SCSI reserves
  ‒ NFS provides the ability to dynamically re-size the VM Datastores
WHY NOT NAS? (DISADVANTAGES)



 Reliability
  ‒ Failover is rapid and clean over Fibre Channel. NFS
    implementations have higher timeouts.
  ‒ IP/Ethernet networks while redundant are not generally as robust

 Performance
  ‒ While you can make NFS perform equal to FC for a given
    workload with the right resources, it will consume more host CPU
    15% upwards (substantial in sequential I/O)
  ‒ Native multi-pathing and load balancing (NFS cannot load balance
    I/O within a datastore)
  ‒ VAAI enabled subsystems have addressed SCSI reserve issues
WHY HITACHI NAS FOR VSPHERE?


 Hitachi NAS offers a highly scalable platform
  ‒ Up to 8 high performance nodes in a single cluster (almost 4X
    more scalable than high end leading vendor)
  ‒ File systems can be extended to 256TB (up to 16X)

 Hitachi NAS provides Tiered File System to maximize vSphere
  performance.
  ‒ Accelerates metadata look ups that occur when processing
    snapshot across many large VMDK files

 Hitachi NAS provides JetClone to provide space efficient copies of
  VMs

 Hitachi NAS is VMware Certified

 JetMirror provides object-based replication over WAN
AMS AND VSP STRONGER THAN OTHER NAS VENDOR

 PURE NAS PLATFORMS HAVE WEAK BLOCK IMPLEMENTATION

  Despite NAS having many software features and dedup, these platforms
   do not have a robust Fibre Channel capabilities:
   ‒ Dual-node failover time (15-45 sec. outage) vs a VSP’s fault tolerant
       architecture with a 100% data availability warranty
   ‒ Does not have active/active symmetric controllers load balancing like
       Hitachi AMS2000
   ‒ LUNs are basically files on a file system, rather than native block
       capability (liable to fragment over time)
   ‒ OS and parity checksum overheads result in lower useable capacity
   ‒ No integrated encryption offering
   ‒ Limited virtualization capabilities
   ‒ Vmware View Composer 5 support intrinsic inline dedup while
       current primary storage dedup are post processing and its operation
       impact host I/O response time
DEPLOYMENT RECOMMENDATION



 Evaluate both options
 It’s not about Block vs File
  ‒ Both are valid options that have strengths and weaknesses

 Think of your storage as a service
  ‒ NFS is a valid option when layered on top of our Enterprise level block
    platform
  ‒ NAS scalability is a must in large or high growth environment
  ‒ Storage is the bottleneck, use automated tiering to balance performance
    and cost

                                     Reduce errors in the selection and
                                      management of VM storage
                                     Increase storage utilization by optimizing
                                      placement
WHAT DOES STORAGE DRS PROVIDE?

•Storage DRS provides the following:
  1.   Initial Placement of VMs and VMDKS based on available space and I/O
       capacity.
  2.   Load balancing between datastores in a datastore cluster via Storage
       vMotion based on storage space utilization.
  3.   Load balancing via Storage vMotion based on latency.

• Storage DRS also includes Affinity/Anti-Affinity Rules for VMs &
 VMDKs;
  • VMDK Affinity – Keep a VM’s VMDKs together on the same
    datastore. This is the default affinity rule.
  • VMDK Anti-Affinity – Keep a VM’s VMDKs separate on different
    datastores
  • Virtual Machine Anti-Affinity – Keep VMs separate on different
    datastores

•Affinity rules cannot be violated during normal operations.
STORAGE DRS OPERATIONS – INITIAL
PLACEMENT

Initial Placement - VM/VMDK create/clone/relocate.

•When creating a VM you select a datastore cluster rather than an
 individual datastore and let SDRS choose the appropriate datastore.

•DRS will select a datastore based on space utilization and I/O load
 trend.

•By default, all the VMDKs of a VM will be placed on the same datastore
 within a datastore cluster (VMDK Affinity Rule), but you can choose to
 have VMDKs assigned to different datastore clusters.

STORAGE DRS OPERATIONS – LOAD BALANCING


Load balancing - DRS triggers on space usage & latency
 threshold.
•Algorithm makes migration recommendations when I/O response time
 and/or space utilization thresholds have been exceeded

•Space utilization statistics are constantly gathered by vCenter, default
 threshold 80%

•Load Balancing is based on I/O workload and space which ensures that
 no datastore exceeds the configured thresholds.

•Storage DRS will do a cost / benefit analysis!

•For I/O load balancing Storage DRS leverages Storage I/O Control
 functionality

  Standardization and open for all vendors
  OS is API-driven which eliminates custom plug-ins into the OS

       Write Same, Zero (Block Zeroing)                                                 Full Copy (Xcopy)

 Eliminates redundant and repetitive                                 Leverages storage array’s ability to mass
 write commands, which means less I/O for                            copy, snapshot and move blocks via SCSI
 common tasks                                                        commands.

 Benefit: Speeds provisioning of new VMs;                            Benefit: Speeds up cloning and storage
 key to supporting large scale VMware or                             vMotion; allows for faster copies of VMs

           Hardware-assisted Locking                                       Thin Provisioning (vSphere 5.0)

 Stop locking LUNs; start locking blocks only.                        TP-STUN - Error Code to Report “Out of
 Offloads SCSI commands to storage array.                             Space” for Thin Volume
 Benefit: Removes SCSI reservation                                    UNMAP – Zero Page Reclaim for Virtual
 conflicts; enables faster locking; improves                          Disks in conjunction with using “Write

  • 3. THE BEST-KEPT INSIDER SECRET: VMWARE VSPHERE 5 CLOUD DEPLOYMENT MICHAEL HEFFERNAN, SOLUTIONS PRODUCT MANAGER, VMWARE PATRICK ALLAIRE, SENIOR PRODUCT MARKETING MANAGER ,
  • 4. AGENDA  Top VMworld 2011 myths  Storage Design and Architecture for vSphere ‒ VMware and Hitachi integration ‒ Hitachi AMS2000 and Virtual Storage Platform formula ‒ VMware storage APIs - VASA and VAAI
  • 5. Myth #1 It makes more sense to deploy vSphere 5 over NFS
  • 6. WHY NAS? (ADVANTAGES)  Flexibility and Cost Savings ‒ vSphere supports iSCSI, FC, FCoE and NFS (IP) ‒ All functionality of vSphere can be exploited over NFS with a few exceptions ‒ Cannot cluster VMs using Microsoft Cluster Server ‒ Cannot boot the Physical host directly from NFS (requires some internal disk) ‒ No true multi-path I/O Engine (although network can provide fault tolerance) ‒ NFS/IP Ethernet perceived as less costly, less complex and more flexible in deployment ‒ NFS provides a level of virtualization that enables it to abstract some physical level constraints – simple provisioning, LUN queue mgmt, VMFS SCSI reserves ‒ NFS provides the ability to dynamically re-size the VM Datastores
  • 7. WHY NOT NAS? (DISADVANTAGES)  Reliability ‒ Failover is rapid and clean over Fibre Channel. NFS implementations have higher timeouts. ‒ IP/Ethernet networks while redundant are not generally as robust  Performance ‒ While you can make NFS perform equal to FC for a given workload with the right resources, it will consume more host CPU 15% upwards (substantial in sequential I/O) ‒ Native multi-pathing and load balancing (NFS cannot load balance I/O within a datastore) ‒ VAAI enabled subsystems have addressed SCSI reserve issues
  • 8. WHY HITACHI NAS FOR VSPHERE?  Hitachi NAS offers a highly scalable platform ‒ Up to 8 high performance nodes in a single cluster (almost 4X more scalable than high end leading vendor) ‒ File systems can be extended to 256TB (up to 16X)  Hitachi NAS provides Tiered File System to maximize vSphere performance. ‒ Accelerates metadata look ups that occur when processing snapshot across many large VMDK files  Hitachi NAS provides JetClone to provide space efficient copies of VMs  Hitachi NAS is VMware Certified  JetMirror provides object-based replication over WAN
  • 9. AMS AND VSP STRONGER THAN OTHER NAS VENDOR PURE NAS PLATFORMS HAVE WEAK BLOCK IMPLEMENTATION  Despite NAS having many software features and dedup, these platforms do not have a robust Fibre Channel capabilities: ‒ Dual-node failover time (15-45 sec. outage) vs a VSP’s fault tolerant architecture with a 100% data availability warranty ‒ Does not have active/active symmetric controllers load balancing like Hitachi AMS2000 ‒ LUNs are basically files on a file system, rather than native block capability (liable to fragment over time) ‒ OS and parity checksum overheads result in lower useable capacity ‒ No integrated encryption offering ‒ Limited virtualization capabilities ‒ Vmware View Composer 5 support intrinsic inline dedup while current primary storage dedup are post processing and its operation impact host I/O response time
  • 10. DEPLOYMENT RECOMMENDATION  Evaluate both options  It’s not about Block vs File ‒ Both are valid options that have strengths and weaknesses  Think of your storage as a service ‒ NFS is a valid option when layered on top of our Enterprise level block platform ‒ NAS scalability is a must in large or high growth environment ‒ Storage is the bottleneck, use automated tiering to balance performance and cost
  • 11. Myth #2 Storage DRS and Profile-Driven storage support tier 1 application requirements
  • 12. Storage DRS and Profile-Driven Storage Overview High IO  Tier storage based on performance Throughput characteristics (i.e. datastore cluster)  Simplify initial storage placement  Load balance based on I/O Tier 1 Tier 2 Tier 3 Benefits  Eliminate VM downtime for storage maintenance  Reduce time for storage planning/configuration  Reduce errors in the selection and management of VM storage  Increase storage utilization by optimizing placement
  • 13. WHAT DOES STORAGE DRS PROVIDE? •Storage DRS provides the following: 1. Initial Placement of VMs and VMDKS based on available space and I/O capacity. 2. Load balancing between datastores in a datastore cluster via Storage vMotion based on storage space utilization. 3. Load balancing via Storage vMotion based on latency. • Storage DRS also includes Affinity/Anti-Affinity Rules for VMs & VMDKs; • VMDK Affinity – Keep a VM’s VMDKs together on the same datastore. This is the default affinity rule. • VMDK Anti-Affinity – Keep a VM’s VMDKs separate on different datastores • Virtual Machine Anti-Affinity – Keep VMs separate on different datastores •Affinity rules cannot be violated during normal operations.
  • 14. STORAGE DRS OPERATIONS – INITIAL PLACEMENT Initial Placement - VM/VMDK create/clone/relocate. •When creating a VM you select a datastore cluster rather than an individual datastore and let SDRS choose the appropriate datastore. •DRS will select a datastore based on space utilization and I/O load trend. •By default, all the VMDKs of a VM will be placed on the same datastore within a datastore cluster (VMDK Affinity Rule), but you can choose to have VMDKs assigned to different datastore clusters. 2TB datastore cluster 500GB 500GB 500GB 500GB datastores 300GB 260GB 265GB 275GB available available available available
  • 15. STORAGE DRS OPERATIONS – LOAD BALANCING Load balancing - DRS triggers on space usage & latency threshold. •Algorithm makes migration recommendations when I/O response time and/or space utilization thresholds have been exceeded •Space utilization statistics are constantly gathered by vCenter, default threshold 80% •Load Balancing is based on I/O workload and space which ensures that no datastore exceeds the configured thresholds. •Storage DRS will do a cost / benefit analysis! •For I/O load balancing Storage DRS leverages Storage I/O Control functionality
  • 16. STORAGE DRS WORKFLOW DRS I/O load trend is evaluated triggers every 8 hours based on a past day history Default threshold 15ms DRS triggers POI DRS triggers NT

  • 18. Myth #3 Storage feature like automated sub-LUN tiering no longer makes sense with vSphere 5 Storage DRS
  • 19. STORAGE DRS VS AUTOMATED SUB-LUN TIERING 1. DRS - Eliminate VM downtime for DRS storage maintenance triggers - Reduce time for storage planning/configuration - Reduce errors in the selection and management of VM storage Datastore DRS triggersP DRS triggers cluster - Increase storage utilization by OI N T optimizing placement Page IO Weights & Tier Ranges 2. SUB-LUN TIERING - Virtualize devices into a pool of capacity and allocate by pages Page relocations - Eliminate allocated but unused waste by allocating only the pages Cycle that are used - Optimize storage performance by spreading the I/O across more Monitor physical IO Datastore arms to pages cluster - Simplify management tasks - Further reduces OPEX - Further Improves Return on Assets
  • 20. It’s Time to Rethink Storage Design & Architecture for vSphere 5…
  • 21. Hitachi + VMware Integration
  • 22. VMware Storage API’s vStorage APIs for Array Integration Storage vMotion VMware ESXi 5.0 Provision VMs From Template API’s Improve Thin Provisioning Disk Performance VMFS Share Storage Pool Scalability Dead Space Reclamation It is all about the ecosystem  Standardization and open for all vendors  OS is API-driven which eliminates custom plug-ins into the OS  APIs leverage each other under the covers
  • 23. vStorage API for Array Integration Write Same, Zero (Block Zeroing) Full Copy (Xcopy) Eliminates redundant and repetitive Leverages storage array’s ability to mass write commands, which means less I/O for copy, snapshot and move blocks via SCSI common tasks commands. Benefit: Speeds provisioning of new VMs; Benefit: Speeds up cloning and storage key to supporting large scale VMware or vMotion; allows for faster copies of VMs VDI deployments Hardware-assisted Locking Thin Provisioning (vSphere 5.0) Stop locking LUNs; start locking blocks only. TP-STUN - Error Code to Report “Out of Offloads SCSI commands to storage array. Space” for Thin Volume Benefit: Removes SCSI reservation UNMAP – Zero Page Reclaim for Virtual conflicts; enables faster locking; improves Disks in conjunction with using “Write VM density performance Same” command on Thin Volume *Note: VAAI is currently supported on the Hitachi Adaptable Modular Series 2000 family, VSP & USPV/VM. # Thin Provisioning API will be supported with ESXi 5.0

Notas do Editor

  1. So.. Is it something specific to NetApp, or is all NAS (regardless of vendor) able to enjoy certain benefits or advantagesvSphere itself supports multiple protocols – iSCSI, FCP and NFS. Generally speaking VMware is agnostic, although they do recognize that FCP provides the most I/O throughput at the expense of the least CPU overhead (everything is offloaded to the HBA). But is it that significant? There are a few things NAS can’t do on vSphere – you can’t using MS Clustering (that requires an RDM or raw device mapping – Microsoft uses SCSI reserves as part of their clustering mechanism). To be honest though, most people don’t cluster their VMs – they use clustering and advanced capabilities of vSphere (DRS/vMotion) to provide HA.You obviously can’t boot from SAN if you’re not using it.. You can’t boot a vSphere machine from an NFS mount. There’s no real multi-path I/O engine – while the network can provide fault tolerance and you can port channel NICs, TCP sessions aren’t load balanced like a pair of FCP adapters and a multi-path I/O driver. Many however feel that this isn’t a significant issue, especially with 10GigE. What people like about NFS is it’s flexibility and ubiquity. The IP network is much more flexible than the SAN, the skill set is common and on a per port basis it’s less expensive. But there are other benefits.. In the fibre channel world I have to think about and manage LUNs, how many VMs per LUN to manage queue depth and until recently I had to worry about VMFS SCSI reserve locking (VAAI addressed that one). In the NFS world all I have to do is create a file system and stick some files on it. On NFS VMs are files.. If I need to expand or shrink the datastore it’s an easy think to do.. VMFS lun re-sizing not to simple.

  5. Goal of this Slide: To introduce: Data drives our world – and information is the new currency. It is the guiding theme for this presentation. This statement embodies the Hitachi Data Systems philosophy and the overall vision and strategy for our products and solutions long-term. Ultimately, this theme of data and information at the center of the economy, of your business, informs how we think about developing our products, our roadmap, and our solutions and services. Speaker’s Notes: (Note to Presenter): As the slide fades in read the slide’s content at a quick pace or ad lib, but emphasize the key takeaways (Note to Presenter):The following slides are meant to be presented at a reasonable pace to capture the audience’s attention, and focus it on several key supporting themes which are introduced in the slides that follow The central theme of what we do at Hitachi Data Systems is: Data drives our world – and information is the new currency. Our customers trust Hitachi Data Systems to protect their data, the raw resource that lies at the heart of your business, whether you’re a <Note to Presenter: Say the type of company your audience is part of>, or Financial Services, Healthcare, Hospital, Media, Entertainment, Retail, the list goes on – Every industry has been transformed or is in the midst of being transformed and perhaps the most common thread running throughout is the value and importance of data, and by extension, information, which is data with meaning, context, value. The following quote from Pete Gerr, Hitachi Data Systems Strategic Marketing Principal from his blog expands on this theme: “Data, the raw resource of today’s economy, is like its analogs in other industries and eras of history: coal, iron, oil, water. However, data itself has little intrinsic value – though its potential value is enormous. Information is data imbued with value. Organized for purpose. Instilled with meaning and context. Ripe for monetization.” (NEXT SLIDE)
  6. Accelerate VM storage placement decision to a storage pod by:Capturing VM storage SLA requirementsMapping to the storage with the right characteristics and spare space
  7. So how exactly does storage drs solve these problems? How will it make your life better?As mentioned first of all and foremost Initial Placement of virtual machines and vmdks. This placement is based on Space and I/O capacity. Storage DRS will select the best datastore to place this virtual machine or virtual disk in the selected Datastore ClusterWhen Storage DRS is set to fully automatic, it will do automated load balancing actions. Of course this can be configured as manual as well and that is actually the default today. Load balancing again is based on space and I/O capacity. If and when required Storage DRS will make recommendations based space and I/O capacity. It will however only do this when a specific threshold is reached.So what is this datastore cluster?
  8. Storage DRS provides initial placement recommendations to datastores in a Storage DRS-enabled datastore cluster based on I/O and space capacity. During the provisioning of a virtual machine, a datastore cluster can be selected as the target destination for this virtual machine or virtual machine disk after which a recommendation for initial placement is done based on I/O and space capacity. As just mentioned Initial placement in a manual provisioning process has proven to be very complex in most environments and as such important provisioning factors like current I/O load or space utilization are often ignored. Storage DRS ensures initial placement recommendations are made in accordance with space constraints and with respect to the goals of space and I/O load balancing. Although people are really excited about automated load balancing… It is Initial Placement where most people will start off with and where most people will benefit from the most as it will reduce operational overhead associated with the provisioning of virtual machines.
  9. Ongoing balancing recommendations are made when one or more datastores in a datastore cluster exceeds the user-configurable space utilization or I/O latency thresholds. These thresholds are typically defined during the configuration of the datastore cluster. Storage DRS utilizes vCenter Server’s datastore utilization reporting mechanism to make recommendations whenever the configured utilized space threshold is exceeded. I/O load is evaluated by default every 8 hours currently with a default latency threshold of 15ms. Only when this I/O latency threshold is exceeded Storage DRS will calculate all possible moves to balance the load accordingly while considering the cost and the benefit of the migration. If the benefit doesn’t at least last for 24 hours Storage DRS will not make the recommendation.
  10. DRS is great to workload trendsThe DRS vMotion recommendation default is manual, the vCenter administrator need to assess if a VM or VMDK can be move without causing any business impact….. remote replication is the limiting factor to take into account

However, data itself has little intrinsic value – though its potential value is enormous. Information is data imbued with value. Organized for purpose. Instilled with meaning and context. Ripe for monetization.” (NEXT SLIDE)

While DRS is a great first step and does assist in initial placement of a VM or VMDK; it is limited to performance trending, it can not support tier 1 application on its own.Storage DRS is limited to the datastore clusterSampling means translate into one daily checkvMotion is neabled in Manual mode due to RPO/RTO impact With the assistance of Hitachi Dynamic Tiering, the implementation provide a much greater agility and resilience required by tier 1 application
  13. Goal of this Slide: To introduce: Data drives our world – and information is the new currency. It is the guiding theme for this presentation. This statement embodies the Hitachi Data Systems philosophy and the overall vision and strategy for our products and solutions long-term. Ultimately, this theme of data and information at the center of the economy, of your business, informs how we think about developing our products, our roadmap, and our solutions and services. Speaker’s Notes: (Note to Presenter): As the slide fades in read the slide’s content at a quick pace or ad lib, but emphasize the key takeaways (Note to Presenter):The following slides are meant to be presented at a reasonable pace to capture the audience’s attention, and focus it on several key supporting themes which are introduced in the slides that follow The central theme of what we do at Hitachi Data Systems is: Data drives our world – and information is the new currency.

  14. Speaker’s Notes:Of the three VAAI features, Hardware-Assisted Locking has perhaps the biggest impact on VMware environments – addressing one of the key challenges organizations face in managing and scaling their storage environments for VMware.While many customers think the management and scaling challenges they are face with VMware are a storage issue, it is really SCSI Reservation that is the real culprit, resulting in: Smaller LDEV size (smaller volumes, fewer VMs) - creating a guessing game of how many VMs could be supported per volume Fewer vMotions – due to the performance impact on the storage (customers implemented change control for vSphereAdmins) Fewer servers accessing the shared LDEV - in an effort not to introduce SCSI reservesSCSI Reservation also affected how organizations power-on servers to reduce boot storms and how backups are done (attempts to stagger them) to avoid performance problem.NOW, with Hardware-Assisted Locking, the ESX hosts are freed up – allowing for much greater densities, improved I/O, etc. The days of spending many hours/weeks/months to designing storage for VMware are gone. Provision up to 2TB Volumes and forget about it.
  15. While scale up storage is a basic requirement to support server virtualization, tighter integration of application and storage virtualization can help to further transform the data center.Why do we need this integration?Applications only have a software view of the infrastructure. It does not know about the infrastructure that lies behind the representation of a LUN and it does not know how to make any changes to that infrastructure.The storage knows about the infrastructure but not what lies beyond the LUN that it lies on the application side of the LUN.
  16. Speaker’s Notes: A highly functioning VMware environment necessitates a flexible, adaptive storage environment – one that integrates with the virtual server environment, is able to dynamically pool and tier resources (performance and capacity) to applications as needed and scales within the same footprint to meet current and future application demands.
