IBM System 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. This device interoperability is the broadest in the industry – incorporating both IBM and non-IBM hardware and tape systems. IBM Spectrum Storage can help reduce storage costs up to 90 percent in certain environments by automatically moving data onto the most economical storage device – either from IBM or non-IBM flash, disk and tape systems.

IBM Spectrum Accelerate offers grid-scale block storage with rapid deployment that helps speed delivery of data across an enterprise and adds extreme flexibility to cloud deployments.

The functionality of Spectrum Accelerate is fully based on the IBM XIV, a high-end disk storage system designed to provide consistent and predictable performance, high availability and simple manageability. 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 flash accelerated, industrial strength, highly scalable software defined storage that enables global shared access to data with extreme scalability and agility for cloud and analytics. The product is very widely used in both commercial and academic environments [reference needed]. It has a long 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 storage virtualization enhances existing storage to improve resource utilization and productivity to achieve a simpler, more scalable and cost efficient IT infrastructure.

The functionality of IBM Spectrum Virtualize is provided by IBM SAN Volume Controller. 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.
