HPE Nimble Storage SSDs

HPE Nimble Storage SSDs are spare cache and all-flash drives in 3.5-inch and 2.5-inch SAS and SATA versions, and each is sold under its HPE or Nimble part number. In CS-Series and HF arrays, SSDs cache data that lives on disk, while AF arrays keep all of it on flash. HPE's CS1000 to CS7000 hardware guide says cache can be upgraded without shutting the array down and, where existing SSDs come out, advises replacing one per 24 hours. In-stock SSDs can ship on the order date; disks are on Nimble hard drives and arrays on HPE Nimble Storage.
