The 4939-A49 is the control enclosure of the IBM Flex System V7000 Storage Node. Like the expansion unit it is a double-high, full-wide node for an IBM Flex System Enterprise Chassis, with twenty-four 2.5-inch SAS drive slots. IBM orders it as feature AD00 or option number 4939H49, and the model family also covers the H49 and X49 variants.
Two node canisters share 16 GB of cache, 8 GB each. Every canister has a four-core Intel Jasper Forest processor, a 32 GB SSD boot device and a management module that connects to the chassis management module. Host connectivity is 8 Gb Fibre Channel, 10 Gb iSCSI or 10 Gb FCoE through host interface cards, and Fibre Channel or FCoE can also be used to virtualize other storage. IBM supports RAID 0, 1, 5, 6 and 10 and the FlashCopy, Metro Mirror and Global Mirror copy services.
Expansion runs over two 6 Gb SAS ports, one per canister. One control enclosure can attach up to two Flex System V7000 expansion enclosures and up to nine Storwize V7000 expansion enclosures, giving 240 drives per control enclosure and 960 per clustered system. Hosts can be Windows, VMware and Linux on x86 compute nodes, or AIX, Linux, VIOS and IBM i on Power compute nodes. Operation needs Storwize family software V7.1 or later.
The expansion unit for this node is the 4939-A29, and further IBM storage hardware is on the IBM storage systems page.
