 (SVC).

Hardware

The Storwize V7000 consists of up to two control enclosures and up to 18 expansion enclosures. It can scale up to 480 disks and 480 TB raw capacity.

The enclosures are available in six varieties:

• Type 2076-112 = Control enclosure + 12 3.5" drives
• Type 2076-124 = Control enclosure + 24 2.5" drives
• Type 2076-212 = Expansion enclosure + 12 3.5" drives
• Type 2076-224 = Expansion enclosure + 24 2.5" drives
• Type 2076-312 = Control enclosure + 12 3.5" drives + 10Gb iSCSI
• Type 2076-324 = Control enclosure + 24 2.5" drives + 10Gb iSCSI

The control enclosure contains two independent control units based on SAN Volume Controller technology, which are clustered via an internal network, using the SVC clustering mechanism. The control units are referred to
as canisters. Each enclosure also includes two PSUs. The control enclosure PSUs each house a battery pack which retains cached data in the event of a power failure. The enclosures are interconnected with wide SAS cables (4 x 6Gb/sec).

Architecture

The Storwize V7000 provides a very similar architecture to SVC, using the RAID code from the DS8000 to provide internal managed disks.

• Peer to Peer Remote Copy
  Peer to Peer Remote Copy
  Peer to Peer Remote Copy or PPRC is a protocol to replicate a storage volume to another control unit in a remote site. Synchronous PPRC causes each write to the primary volume to be performed to the secondary as well, and the I/O is only considered complete when update to both primary and secondary...
