3. AGENDA






Introduction – Elastic Cloud
Tools & Utilities
Hardware elasticity
OS elasticity
Network elasticity
Storage elasticity

4. Introduction – Elastic Cloud
Amazon elasticity – Ability to pay per quantum of time.
So where is the elasticity ?

5. Introduction – Elastic Cloud






Cloud elasticity – Do IT online !!!
Ability to change resources of a VM – online.
Ability to utilize and share the hardware better – online.
Ability to change hardware to your specific needs – online.
Ability to utilize the OS better for its’ specific needs – online.
Ability to utilize the Network and storage better – online.

6. Tools & Utilities
Enterprise Manager SUITE

Oracle Cloud control –
Mainly manages application tier
Oracle DB, Weblogic, SOA,
Glassfish, etc...

Oracle OPS Center –
Manages Hardware, OS, Hypervisors,
VM’s, Storage, Network Fabrics, etc…

Oracle VM Manager –
Manages OVM X86 & SPARC

7. Tools & Utilities


Oracle VM for SPARC
A set of packages (in Solaris 10/11)
that offers HW virtualization in
T-series servers.
Oracle VM for x86
A Xen based hypervisor that operates
as a Hypervisor for X86 platforms.
Both offers: CLI or GUI management via
OPS Center – or – VM Manager

8. Hardware Elasticity

Imagine your hardware
can transform itself from
1 core = 8 vcpu (max-throughput)
to
1 core = 1 vcpu (max-ipc)
This can be done via Oracle VM for SPARC Control domain
e.g.: ldm set-core threading=max-ipc | max-throughput ldom
* This feature is deprecated but was brought to emphasize the elasticity of SPARC platform.

9. Hardware Elasticity
Ldom elasticity policy
ldm add-policy [enable=yes|no] [priority=value] [attack=value]
[decay=value] [elastic-margin=value] [sample-rate=value] [todbegin=hh:mm[:ss]] [tod-end=hh:mm[:ss]] [util-lower=percent]
[util-upper=percent] [vcpu-min=value] [vcpu-max=value]
name=policy-name ldom...


Oracle VM for SPARC supports mixed Solaris versions
Support for running Solaris 10 and Solaris 11 VMs.

10. OS Elasticity






Critical thread – ability to bring CPU bound process more
hardware space. (by setting the priority of this process to 60
using FX priority or RT scheduling classes).
Datalink Multipathing Aggregations – Overcomes the
single switch boundary.
Multipathing – IO Multipathing supports mixed paths (e.g.:
iscsi, fcoe and fc together.)
FC – FC lun changes are reflected immediately.
Fast reboot mechanism – by using: reboot –s
OS Snapshots – Snapshot a root file-system within the OS
using: beadm

11. OS Elasticity – cont.



Patching & Upgrading – patching and upgrading using liveupgrade can be rolled back.
Ability to run zones – a lightweight virtualized VM with a
lower footprint.
Ability to run branded zones – Solaris 10 zones.

12. Storage Elasticity



ZFS – Ability to add devices, ability to split pool, ability to
grow luns of a pool on the fly – online.
Multipathing – IO Multipathing supports mixed paths (e.g.:
iSCSI, FCoE and FC together.)
NPIV – N_Port ID Virtualization is a Fiber Channel facility allowing multiple N_Port IDs
to share a single physical N_Port. This allows multiple Fiber Channel initiators to occupy a
single physical port, easing hardware requirements in Storage Area
Network design, especially where virtual SANs are called for.

COMSTAR - ability to create luns and expose them using
FC/FCoE/iSCSI etc…

13. Network Elasticity



Datalink Multipathing Aggregations – overcome the single
switch boundary. Ability to add or remove devices – online.
SR-IOV – Single root IO virtualization now supports NIC that
can expose itself as several virtual devices. Each virtual
device is a physical entity in the card. Packet manipulation is
done by the hardware.
Network virtualization – ability to create switches and vnics
and to attach it to zones.
