4 Introducing the New DS8700 The Next Chapter in IBM s Flagship Disk Platform What s New Why Move to DS Performance Up to over 150% performance boost with new IBM POWER6-based controllers New, faster PCI Express (PCI-E) internal fabric enables much higher performance and scalability Almost 70% faster ASIC on the device adapters Increased FlashCopy performance in every metric Increased SSD performance on sequential reads Availability Single model, scalable via concurrent upgrade of all components Shorter service windows with faster concurrent microcode updates Better than % availability Investment Protection and Scalability DS8700 architecture allows for future expansion of additional controllers and future 8Gb Host Adapters Future features, such as SSD optimization and M/GM Multiple Session coming soon Management Simplified management and application-aware FlashCopy Security Full Disk Encryption enhancements address PCI-DSS compliance

5 Changing from DS8000 to Follow-on DS8700 PCIe cable I/O attach Change in I/O structure Change in I/O DS8000 RIO I/O attach structure New I/O attach P5 P5 P6 P5 P5 P6 RIO P6 server RIO P6 P6 Disks 5 PC Ie c a New IO bays are directly connected to the servers via point to point PCI e cables. IO Towers no longer share common loops, they connect directly to each server via separate cables and link cards. The server to server communication path continues to use RIO, but is now isolated from IO traffic. ble s Disks 4.7 Ghz P6 570 x2 Cache GB 4 Gb/s FC / FICON 2 Gb/s disk array

15 New SVC 2145-CF8 Storage Engine New SVC engine based on IBM System x3550m2 server Intel Xeon GHz quad-core processor Triple cache size to 24GB (with future growth possibilities) Four 8Gbps FC ports Bandwidth twice that of the Model 8G4 Expect double MB/s and up to double IOPS of Model 8G4 Significant price/performance improvement Enables support of more demanding and larger configurations with fewer SVC engines Support for Solid State Drives (up to four per SVC node) enabling scale-out high performance SSD support with SVC New engines may be intermixed in pairs with other engines in SVC clusters Mixing engine types in a cluster results in VDisk throughput characteristics of the engine type in that I/O group Cluster non-disruptive upgrade capability may be used to replace older engines with new CF8 engines 15

16 SVC Configurations With 2145-CF8 Minimum Configuration (One I/O Group) Maximum Configuration (Four I/O Groups) 48GB 192GB 8Gb Fiber Channel Ports Gb iscsi Ports 4 16 SSDs GB (two SSDs) 2.4TB Cache Mirrored SSD Capacity 16

17 SVC Software Version 5 Support for iscsi server attachment Replication enhancements including Multiple Cluster Mirror, increased number of remote copy relationships, and Multi-Target Reverse FlashCopy Supports consolidated disaster recovery site servicing more than one production location Enables larger configurations to be protected with up to 8192 MM/GM relationships FlashCopy targets may be used almost immediately as restore points enabling faster recovery New 64-bit SVC software base Supports all SVC engines available since October 2005 (8F2, 8F4, 8G4, 8A4, CF8) Cache management enhancements Improves throughput up to 15% for existing systems, especially for write I/Os Available for existing customers with current subscription and support at no charge Nondisruptive upgrade from SVC software

18 Multiple Cluster Mirroring Configuration Rules Max 4 clusters connected by partnerships either directly or indirectly All must be at 5.1 even if a cluster is only in one partnership B C A C A A B D B C D Unsupported configuration: 5 clusters in a connected set A B C D E A VDisk can only be in one MM or one GM relationship A FlashCopy target cannot be a MM or GM source Enables Metro and Global Mirror relationships between up to four SVC clusters Three site Metro-Global Mirror like DS8K not supported Replication of a VDisk to multiple sites not supported D

19 Thin Provisioning Enhancements: Zero Detect When using Virtual Disk Mirroring to copy from a fully-allocated virtual disk to a space-efficient (thin provisioned) virtual disk, SVC will not copy blocks that are all zeroes Disk space is not allocated for unused space or formatted space that is all zeroes When processing a write request, SVC will detect if all zeroes are being written and will not allocate disk space for such requests Helps minimize disk space used for space-efficient virtual disks Helps avoid space utilization concerns when formatting vdisks Supported only on Model CF8 storage engines 19
