- The audience for this presentation is sales and pre sales personnel from our enterprise and enterprise elite channel partners. These partners are authorized to sell ESL, EML, VLS as well as other enterprise storage products. While they are also authorized to sell business class storage the focus of this content is on the enterprise data protection solutions.
- Not meeting Backup Window What they do today Gamble – run risk of losing data Impact production environment – accept lower performance until backup jobs have completed In many companies, nightly backup reports are delivered up the IT management infrastructure. Excessive backup failures (either on success rate or SLA basis) have visibility How the VLS solves the problem Accelerates backup performance by allowing more jobs to happen at the same time so the backup windo w is achieved Improves process reliability (removes tape handling, bad media, and physical drive related errors) Removes infringement of the backup jobs on the production resource Reduces failures and SLA violations resulting in fewer reportable incidences Slow Restores What they do today Devote storage administrator resources for this task at the expense of other activities (e.g. development) Accept lower productivity of department that is waiting on resources – LOST $$$ How the VLS solves the problem Reduces the restore time thus off-loading storage administrators and help desk operators more time to do application development!!! Allows quicker time to productivity by resources that were affected by data loss more productive workforce!! Inefficient media usage What they do today Purchasing more media Over-paying for offsite services – since more media than is necessary goes offsite, the subscription/retrieval costs are higher than necessary How the VLS solves the problem Reduces the number of tape copies required Many customers are cloning tapes – one for onsite, one for offsite. This eliminates the onsite media expense (onsite media expense is recurring due to media wear-out) More efficiently fills media resulting in fewer pieces needed Some customers are not fully filling media for various reasons Complexities with multiplexing streams from the LAN Short backups such as Database re-do logs Copy jobs de-multiplex the virtual media to physical media and put data back to back resulting in better usage Perishable data is never sent to tape media (database redo logs are only good until the next backup).

- INITIAL VIEW: Here’s a look at a typical virtual tape solution. Let’s look at how data flows to the VLS and tape library. BUILD 1: “STEP 1” BOX AND BLUE LINES APPEAR The first step is to back up slow SAN servers and LAN servers to the SAN-attached VLS. With LAN data, instead of multiplexing the data to a physical tape drive we can create a virtual tape drive for each server on the LAN. Slow servers on the SAN include data types such as web, file and print servers. Virtual tape drives also enable backup for servers that can’t stream data to a physical tape drive or have a data type that is conducive to single file restores. BUILD 2: GREEN LINE APPEARS Faster data is backed up directly to the tape library. Taking fast data directly to tape storage is more economical. While you could take everything to the VLS, the direct-to-tape approach offers the advantages of low $/GB of storage, low power consumption and easy offsite storage, among other benefits. BUILD 3: “STEP 2” BOX AND RED LINE APPEAR Once all of the data has been backed up, Step 2 is to copy the data from the VLS over to physical tape for easy offsite storage. This diagram shows the data flow going back through the backup server. Using the backup server to make these copies enables: Media concatenation (taking the small virtual cartridges created from the LAN backup to one or a few physical cartridges, depending the amount of data) Setting different virtual and physical media retention times A single point of management for location of data in the event of a restore BUILD 4: “RESULTS” BOX APPEARS A VLS-based virtual tape solution that follows the approaches outlined here delivers a wide range of benefits: It helps you accelerate backup for a consolidated SAN environment. Based on calculations for a typical SAN environment, HP estimates that virtual tape can reduce backup windows by up to 42 percent. It helps you improve recovery times for single files, as well as overall recovery times It reduces server bottlenecks and resource constraints. It gives you a more agile environment, so you can respond faster to change. Later in this presentation we’ll talk about automigration. It enables a different data path flow for copying data from the VLS to physical tape.
- HP offers a whole range of disk-based backup products that can help organizations meet their data protection challenges. You probably already know that moving the front line of data protection from tape to disk reduces administrative overhead. Daily backup becomes entirely automated and involves no tape handling, giving better backup reliability and less worry. But most companies measure the success of a data protection system by how quickly and completely they can restore data when needed. As I mentioned earlier, HP has chosen two different types of deduplication for its disk-based backup products to meet the needs of different customers. As you can see, the majority of the product range now includes data deduplication. At the entry level, we offer the D2D100 series Backup System. These 100-series products – including the latest D2D130 Backup System – was introduced last year to meet the needs of small businesses. This is a low-cost solution that does not incorporate deduplication technology. The new members of our D2D Backup System family are the D2D2500 and D2D4000 series. The D2D2500 is well suited for remote and branch offices and small IT environments, while the more powerful D2D4000 is designed for medium-sized companies and small data centers. These products include HP Dynamic deduplication, which is designed with low cost and flexibility in mind to meet the needs of smaller IT environments. HP Virtual Library Systems, which have been around for a couple of years, are known for their easy integration, simple management and fast restores. The VLS6000, VLS9000 and VLS12000 EVA Gateway are designed for medium to large-scale enterprises. They now feature Accelerated deduplication, available by license, to deliver the best backup performance and scalability for high-availability data center environments. We’ll now go on to look at Accelerated deduplication and Dynamic deduplication in more detail.
- Use this slide to go into detail on the VLS6000 but I have it hidden to save time
- VLS9000 is a combination of gateway and appliance model for VLS. It has the multiple node capabilities of a gateway with the easy to set up auto-configuration of the array from the 6000. By allowing the flexibility for use of 20-port and 32-port connectivity kits, the VLS9000 can have a lower level of entry. The node expansion kits allow users to expand their systems past the single cell configuration. With the 32-port kit you can have a maximum configuration of 240TB and 4800 MB/s
- VLS9000 is a combination of gateway and appliance model for VLS. It has the multiple node capabilities of a gateway with the easy to set up auto-configuration of the array from the 6000. By allowing the flexibility for use of 5 node and 8 node expansion kits, the VLS9000 can have a lower level of entry. The node expansion kits allow users to expand their systems past the single cell configuration. With the 8 node kit you can have a maximum configuration of 240TB and 4800 MB/s The VLS9000 and EVA Gateway will have the capability to have High Availability (HA) during 1H CY’08. This feature will allow one node to automatically fail over to the another.

If duplicate data is found, a pointer is established to the original set of data as opposed to actually storing the duplicate blocks—removing or “de-duplicating” the redundant blocks from the volume. The key part of this is that the data deduplication is being done at the block level, typically, and not at the file level. In fact, beware of products that only de-dupe at the file level (more on that later). Say, for example, you are backing up a very large database that changes throughout the day. With the typical backup application you have to back up, and more importantly store, the entire database with each backup. An incremental won't help you here. With block-level deduplication, you can backup the same database to the device on two successive nights and, due to its ability to identify redundant blocks, only the blocks that have changed will be stored. All the redundant data will have pointers established.
