IBM FlashSystem 7200 Control Enclosure (2076-824)

2076-824 is the IBM FlashSystem 7200 control enclosure, a 2U all-flash NVMe enclosure that supports up to 24 NVMe-capable flash drives and runs Spectrum Virtualize. Machine type 2076 has two control models, 824 and U7C. The U7C is physically and functionally identical to the 824, differing in target configurations and variable capacity billing.

Two node canisters hold four 8-core processors between them, with hot-swappable batteries, PCIe adapters, power supplies, DIMMs and fans. Cache is 256 GB at the base (128 GB per canister) and goes to 768 GB with feature ACGJ or to 1.5 TB with ACGB added. Eight 10 Gb Ethernet ports are standard for iSCSI, adapters add 32 Gb or 16 Gb Fibre Channel, 25 Gb Ethernet and 10 Gb Ethernet, and two 1 Gb Ethernet ports handle management. Six PCIe slots are available, three per canister, and both canisters need the same configuration.

Drive options are 2.5-inch NVMe: FlashCore Modules of 4.8, 9.6, 19.2 and 38.4 TB, industry-standard drives of 800 GB, 1.92, 3.84, 7.68 and 15.36 TB, and up to 12 Storage Class Memory drives of 375 GB, 750 GB, 800 GB and 1.6 TB. All drives are dual-port and hot-swappable, and flash modules in one DRAID 6 array must be the same type and capacity.

Up to four control enclosures can be clustered. SAS expansion uses 12G (LFF), 24G (SFF) and 92G (5U high-density) models, and the V7000 expansion models 12F, 24F and 92F can also attach to a 2076-824 and mix with them.
