Easy Tier is designed to relocate data (at the extent level) across up to three drive tiers automatically and without disruption to application. IBM Easy Tier is available on the DS8000, Storwize (V7000, V7000 Unified, V5000, V3700 lines) and SAN Volume Controller.

Current hardware

After 2019, IBM dropped the HDD and SSD-based storage server series and all current lines provide only flash-oriented or tape-oriented solutions.

Flash storage

IBM FlashSystem

IBM FlashSystem is a range of dedicated, non-SSD "all-flash" storage systems, based on a Intel x86 platform.

IBM acquired flash storage system maker Texas Memory Systems in 2012.^[11] In April 2013, IBM announced a plan for a $1 billion investment in flash storage research and development,^[12] and then the product line-up was renewed in 2014 with the announcement of the FlashSystem 840^[13] and FlashSystem V840.^[14] IBM has been updating these models every year. The former IBM FlashSystem had 1U-size solutions only, but the current lineup contains rackable systems with 1U, 2U or 6U form-factor, and based on a 6U modules cabinet-size solution.

In 2017, FlashSystem brand replaced the XIV brand, and in 2020, FlashSystem replaced the Storwize brand.

IBM Data Engine for NoSQL – is an integrated black-box device combining an IBM PowerLinux server with FlashSystem modules attached as non-volatile memory extension (not as storage).The integrated system offers large capacity NoSQL services based on pre-loaded Redis, Cassandra and Neo4J, up to 57 TB in-memory instances.

DS servers

Transparent Cloud Tiering for Swift- and S3-compatible object datastores can be used as a cold tier for incremental volume snapshots and volume archives without live production access. This allows keeping hourly time machine copies or archiving VM images including attached volumes at a price point somewhat closer to tape media. Supported on-premise datastores include IBM Cloud Object Store (aka Cleversafe) and IBM Spectrum Scale object. Off-premise datastores would be popular S3-compatible cloud services like IBM Bluemix (aka Cleversafe cloud). Off-premise Transparent Cloud Tiering per default uses AES encryption, which is a licensed feature.

HDD/SSD storage – High density rack systems

IBM Storwize High-Density Expansion 5U92 for Storwize V5000 Gen2, V7000 and SAN Volume Controller, attaching via 12Gb SAS lanes.
