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.[1]

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 formerly 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 (Solid State Drives) 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

Further information: IBM_Tivoli_Storage_Manager

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.[2]

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.

Flash Storage

IBM FlashSystem offers a range of dedicated, non-SSD "all-flash" storage systems and provide flash capacity for a number of integrated systems. In April 2013, IBM announced a plan for a $1 billion investment in flash storage research and development.[3] IBM acquired flash storage system maker Texas Memory Systems in 2012.[4]

The product line-up was renewed in January 2014 with the announcement of the FlashSystem 840[5] and in February 2014 with the announcement of the FlashSystem V840.[6] Both products were improved in May 2014 with new entry level capacity points and more protocols.[7] IBM has been refreshing those systems and adding new capabilities every year. IBM FlashSystem products are covered under warranty against flash wear.

IBM FlashSystem A9000

IBM FlashSystem A9000 is a 8U rackmount unit with up to 300TB of usable storage capacity provided by FlashSystem 900 modules, managed by IBM Spectrum Accelerate software. It's scalable sibling, the FlashSystem A9000R, consists of a minimum of two units, scaling to 6 units or 1.8 PB usable in a 42U rack. A9000R units share CPU, cache and access paths with their neighbours, leveraging a zero-tuning data distribution design. The FlashSystem A9000 family supports IBM Real-time Compression, real-time global deduplication and real-time pattern removal, while maintaining average access times of 250 µs under database workloads. Up to 144 instances of FlashSystem A9000 and XIV Storage Systems can be combined into one HyperScale cluster with client multitenancy. Since A9000, A9000R and XIV Storage Systems share the Spectrum Accelerate management software, the FlashSystem A9000R is occasionally referred to as XIV Gen4.
