The 4939-A29 is the expansion enclosure of the IBM Flex System V7000 Storage Node. It is a double-high, full-wide node that installs in an IBM Flex System Enterprise Chassis instead of a rack shelf. Inside are two expansion canisters, two management modules that link to the chassis management module, and twenty-four 2.5-inch drive bays running at 6 Gb SAS. IBM orders it as feature AD01 or option number 4939H29, and the model family also covers the H29 and X29 variants.
Each expansion canister has two 6 Gb SAS ports side by side, four in total, to connect upstream to the control enclosure and downstream to the next enclosure. A Flex System V7000 control enclosure supports a maximum of two Flex System V7000 expansion enclosures, plus up to nine Storwize V7000 expansion enclosures of the 2076-212 and 2076-224 type. The whole system tops out at 240 drives per control enclosure and 960 per clustered system.
Before ordering, confirm the chassis, because the node needs a Flex System Enterprise Chassis with the components to host it, and the control enclosure runs Storwize family software V7.1 or later.
The matching control enclosure is the 4939-A49, and the IBM storage systems page covers the rest of the range.
