New IO bays are directly connected to the servers via pointtopoint PCIe cables.

IO Towers no longer share common ‘loops’, they connect directly to each server via separate cables and link cards.

The servertoserver communication path continues to use RIO, but is now isolated from IO traffic.

New SVC 2145-CF8 Storage Engine

New SVC engine based on IBM System x3550M2 server Intel® Xeon® 5500 2.4 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

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 4.3.1


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

Unsupported configuration: 5 clusters in a connected set

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

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


Uninterruptible storage failover between two datacenters

If location (A) fails, (B) can work with the same virtual HDDs and vice versa.
