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.

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

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 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 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 fail over between two data centers, and can have SSD that can be used by EasyTier software to perform sub-LUN automatic tearing.

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

IBM Spectrum Protect is a progression of the Tivoli Storage Management product.^{[citation needed]}
