Let’s go a little deeper and see how we accomplish this virtualization. We’ll start by looking at a trtaditional RAID controller. Out the top of a RAID controller comes a set of LUNs that each correspond to physical disk capacity. (click) It is the job of the RAID controller to map these LUNs to slices of capacity from the physical disk drives behind the controller. (click) The problem is that host systems see the LUNs that are surfaced by the RAID controller meaning that every time you make a change in your controllers, the host systems have to adapt. (click)
To describe the environment with the SAN Volume Controller, we’ll add a tag on the left showing the SCSI LUNs that are surfaced by the RAID controller. (click) These SCSI LUNs will now be mapped 1-for-1 to a new entity called Managed Disks. The RAID Controller thinks he is still talking to a host system – but he’s not. He’s talking to the SAN Volume Controller Managed Disk. (click) On the top end we’ll add another new entity – the Virtual Disk. Host systems connect to these and believe they are still talking to the RAID controller – but they’re not. They are talking to the SAN Volume Controller Virtual Disk. (click) It’s the job of the SAN Volume Controller to manage the mapping between virtual disks and managed disks. (click) To help you in defining how you want your storage mapped, you can create managed disk groups. For example, RAID Controller 1 might be high performance enterprise-class disk and RAID controller 2 might be low-cost S-ATA disk. Now, when the server on the left needs 10GB of high-performance capacity, the job of creating that capacity is straight forward. (click) The SAN Volume Controller effectively insulates host systems from the physical storage on the back end.
Now suppose you have two physical disk systems virtualized by the SAN Volume Controller. Let’s say that the green one is a high-end system from vendor “A” and the red one is a low-cost system from vendor “B”. You want to make a Point-in-time copy – what we call FlashCopy – of the primary data on the green. Because you have a virtualized environment (click), you can send that copy to the lower-cost red controller. (click) Now suppose you want to keep a continuous replica – what we call Peer-to-Peer Remote Copy (or PPRC) – at a remote site. Over at the remote site you have another high-end “green” disk system but you also have a lower-cost blue system from vendor “C”. Because you have virtualized your environment, (click) your continuous copy target can be on the lower cost system. (click)
Now, you have an application that has data on the disk systems from vendor “A” and “B”. You want to create a continuous copy of that application and send it to the disk system from vendor “C”. (click) With the SAN Volume Controller you have the flexibility to do that – and the SAN Volume Controller will ensure that all the data from both source systems is kept in synch so the application is consistent when it reaches the other side. The TotalStorage SAN Volume Controller – improving the flexibility of your disk storage infrastructure. (click)

For clients who need options for storage management there are two options offered, the first is out of the box management and is browser-based, this is included with IBM Storwize V7000, this option is well suited for clients that need simple and basic configuration and management capabilities from a single device for set up and management. The second option is for more complex, value-add storage management, this is achieved by using Tivoli Storage Productivity Center and is supported with IBM and non-IBM storage for complex storage environments with dedicated storage administrators. This option offers end to end storage management with advanced storage management value. Now, let's turn to chart 21…
For clients who need options for server and storage management, two options are offered. Option one for I ntegrated IBM server and storage management that includes Systems Director + Storage Control, applies to internal and external IBM storage and IBM servers such as Power, System x, and BladeCenter. Usage can include midmarket and smaller large enterprise clients with system administrators who cover both server and storage management. These clients can realize value by managing all the IBM servers and storage devices from one pane of glass. Option two for Integrated IBM server and storage management with storage administration specialization applies to Internal and external IBM storage IBM servers such as Power, System x, and BladeCenter. Usage can include large clients with administrators responsible for system and virtualization management with storage management specialization administrators working in concert. These clients can realize value in an Integrated platform, and virtualization and system pool management tightly integrated with advanced storage management. Now, let's turn to chart 22 …
IBM Systems Director Storage Control offers a c entralized management to reduce costs and complexity across server and storage. Integrated to support d iscovery, inventory, alerts, monitoring, configuration, and provisioning. IBM Systems Director Storage Control With VMControl offers the client integrated virtualization management across server, storage, and network. Allows storage provisioning for image creation, deployment, and cloning, and the ability to take group actions across pool and policy based storage placement, provisioning, and cloning actions within the pool.
