IBM storage
The IBM Storage product portfolio includes disk, flash, tape, NAS storage products, storage software and services. IBM's approach is to focus on data management.

Software

IBM Spectrum Storage
IBM Spectrum Storage portfolio can centrally manage more than 300 different storage devices and yottabytes of data.

IBM Spectrum Accelerate
The functionality of Spectrum Accelerate is based on the IBM XIV, a high-end disk storage system. IBM Spectrum Accelerate and XIV run the same base software stack and interoperate with features such as management, remote replication and volume mobility.

IBM Spectrum Scale
IBM Spectrum Scale is software-defined storage for cloud and analytics.
The product is very widely used in both commercial and academic environments. It has a history going back to the mid 1990s. It was known as GPFS before IBM re-branded all storage products in 2015.

IBM Spectrum Virtualize
IBM Spectrum Virtualize is a block storage virtualization system. Because the IBM Storwize V7000 uses SVC code, it can also be used to perform storage virtualization in exactly the same way as SVC. Since mid-2012 it offers real time compression with no performance impact, saving up to 80% of disk utilization. SVC can be configured on a Stretched Cluster Mode, with automatic failover between two datacenters and can have SSD that can be used by EasyTier software to perform sub-LUN automatic tiering.

IBM Spectrum Control
IBM Spectrum Control provides infrastructure management for virtualized, cloud and software-defined storage.

IBM Spectrum Protect

IBM Spectrum Protect is a progression of the Tivoli Storage Management product.

IBM Spectrum Archive
It allows users to run any application designed for disk files against tape data without concern for the fact that the data is physically stored on tape.

IBM offers four options:  
 IBM LTFS Single Drive Edition - access and manage data on a standalone tape drive as if the data were on disk
 IBM LTFS Library Edition - access and manage data on single or multiple cartridges in a tape library
 IBM LTFS Storage Manager - manage both online and offline files in IBM tape libraries
 IBM LTFS Enterprise Edition - run applications designed for disk files from tape storage.

IBM SmartCloud Storage Access
IBM SmartCloud Storage Access is a software application designed to create a private cloud storage service on existing storage devices. The software can be configured to allow users self-service, Internet-based access for account creation, storage provisioning and file management. The software offers simple management with monitoring and reporting capabilities, including storage usage by user and group definitions.

Active Cloud Engine
The Active Cloud Engine (ACE) is an advanced form of multiple site replication. ACE is designed to allow different types of cloud implementations to exchange data dynamically. ACE does is designed to extend the SONAS capability for a single, centrally managed namespace, to a truly distributed, geographically dispersed, global namespace.

IBM Easy Tier
IBM Easy Tier is designed to automate data placement throughout the disk pool to improve the efficiency and performance of the storage system. 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 offers a range of dedicated, non-SSD "all-flash" storage systems and based on a Intel x86 platform.

IBM acquired flash storage system maker Texas Memory Systems in 2012, In April 2013, IBM announced a plan for a $1 billion investment in flash storage research and development, and then the product line-up was renewed in 2014 with the announcement of the FlashSystem 840 and FlashSystem V840.   IBM has been refreshing those systems and adding new capabilities every year. Former FlashSystem has 1U-size solutions only, 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 replaces XIV brand, and in 2020 FlashSystem replaces 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. Compared to a clustered in-memory implementation, the Data Engine for NoSQL consumes a fraction of the power and rack footprint while delivering similar performance by keeping relevant (hashing) data structures in fast memory. Use cases include scalable web shops, gaming, genomics, geolocation, catalogs, hash tables and cluster caches like memcached.

DS servers
IBM Power-based storage series, that offers specialized advanced functions optimized for IBM Power Systems and IBM Z servers; This line early known as System Storage DS series, and former TotalStorage DS series; current models slowly dropped the "System Storage" naming prior to simple line names (DS#### for flash systems, TS#### for tape storage). Currently DS series contains only DS8000 sub-line.

DS8000 series

The DS8000 line formerly offers only as an assembled cabinet-size solution, but current line-up contains half-rack mountable model. The DS8000 also can use self-encrypting drives for every drive tier to help secure data at rest.

Tape and virtual tape systems

TS libraries and servers
Like the similar DS storage series, the tape system lines early known as System Storage TS series or former TotalStorage TS series and based on a IBM POWER controllers.
TS7000 series

Mainframe-oriented virtual tape library series, TS7700 line released in 20## as System Storage 7700, updated in 201#, 2016, 2018 and 2020
Like the DS8000 series, current models can be offered as assembled rack-size solution, or as half-rack rack-mountable system.

TS4500
General purpose tape library series.

TS4300

TS2900

PureData servers 

Was introduced in 2012 for replacing the Netezza line.

Flash storage

IBM DeepFlash

 DeepFlash 150 - is an ultra-high density SSD, based on a SanDisk InfiniFlash IF100 drawer (holding up to 0.5 PB of Flash capacity in 3U rack space) and IBM Spectrum Scale software. It is directly attached via SAS to a maximum of 8 servers used as application cluster or as integrated device running some SDS storage management software. Its design point is lowest price per reliable capacity. In contrast, for lowest price per IOPS or best latency per invest, consider storage built around FlashSystem modules. Introduced in 2016.
 DeepFlash Elastic Storage Server - an integrated device combining one or two DeepFlash 150 drawers with IBM Spectrum Scale software for Exascale storage repositories with analytics capabilities (Hadoop, CCTV, analytics archive, media server etc.). The DeepFlash-ESS can be clustered non-disruptively with existing IBM Elastic Storage Servers, up to a theoretical limit of 8000 clustered devices. It features file (NFS, SMB), object (Swift, S3) and Hadoop transparent access. Spectrum Scale offers automated data placement and lifecycle management from Memory to Flash to Disk to Tape, besides geographically distributed caching and replication.

Other flash storage capabilities

High IOPS PCIe Adapters – PCIe card adapters for former IBM System x servers, offering capacities up to 2.4 TB. Moved to Lenovo.

HDD/SSD storage - For entry and midrange workloads

IBM XIV 

The IBM XIV Storage System was configured as cabinet-size solution and designed to work well in cloud and virtualized environments. The last XIV Gen3 model offers 2, 3, 4 or 6 TB drives, providing up to 485 TB of usable capacity per rack. SSD caching (available as an option) adds up to 12 TB of management-free high-performance data caching capability to the entire array. The system can also connect to external storage via Fibre Channel (8Gbit/s) and iSCSi (1 or 10 Gbit/s). The XIV line was replaced by IBM FlashSystem line.

IBM Storwize family

The Storwize family of storage controllers shares the software with the IBM SAN Volume Controller and offers the same functionality with few exceptions. Storwize systems are capable of external virtualization, and oriented for technology migration and investment protection for aging systems. Storwize advanced caching, free-of-charge Easy Tier (automatic data placement) and automatic hotspot elimination help infuse a second life to previous-generation storage systems. Modern virtualization functions like inline real-time compression for data on external systems can help delay capacity repurchase for several years.

 Storwize V7000 series - announced in 2010, is a compact (2U rack-mount enclosure) virtualizing storage system that inherits IBM SAN Volume Controller (SVC) functionality. 
 Storwize V7000 Gen1 - can attach to storage clients via FCP (8 and 16 Gbit/s), FCoE or iSCSI (1 or 10 Gbit/s) protocols and can use Real-time Compression to reduce disk space usage by up to 80 percent.
 Storwize V7000 Gen2 and Gen2 turbo, each a technology upgrade with increased throughput and number of drives support: 720 slots per single controller or 3040 per clustered controller.
 Storwize V7000F - designed for SSD-only operations.
 Storwize V7000 Unified combines two head units running IBM Storwize File Module Software with the IBM Storwize V7000 block storage system. It is described as unified storage because it simultaneously implements NAS protocols (such as SMB and NFS) and block storage. It leverages IBM Spectrum Scale software capabilities.
 Storwize V7000 Gen3 - last upgrade of V7000 line, before merging to FlashSystem in 2020.
 Storwize V5000 series - announced in 2013, is a mid-range virtualizing storage system offering many of the features of the V7000 in a 2U rack-mount enclosure.
 Storwize V5000 - supports 6 Gbit SAS and 1 Gbit iSCSI host attachment and either 8 Gbit FC or 10 Gbit iSCSI/FCoE host attachment. The system can support up to 480 drives with nineteen expansion enclosures, and up to 960 drives in a two-way cluster configuration.
 Storwize V5000 Gen2, a technology upgrade with increased number of drives support. It is available as V5010, V5020, and V5030 with mutual in-place upgrade capability.
 Storwize V5000F - designed for SSD-only operations.
 Storwize V5000 Gen3 - last upgrade of v5000 line, before merging to FlashSystem in 2020.
 Storwize V3700 - announced in 2012, is an entry-level 2U system, oriented for the block storage needs of small and midsize businesses. This system offers consolidating and sharing data capabilities previously available in more expensive systems. 
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.
This high density carrier hosts 92 hot-swappable large form factor drives in 5U rack height. Use cases include general footprint reduction, active archives, streaming media applications, or big data warehouses.

Peak performance figures are equivalent to four chained 2U Storwize EXP 12Gb SAS expansions, at equal total number (and type) of drives.
