IBM Storwize


IBM Storwize systems were virtualizing RAID computer data storage systems with raw storage capacities up to 32 PB. Storwize is based on the same software as IBM SAN Volume Controller.
Formerly Storwize was an independent data storage organisation.

Models

Сollateral lines:
The Storwize family offers several members:
  • High-end 7000 line:
  • * IBM Storwize V7000 Gen3 - Capacity on up to 760 modules and the capability to use FlashCore modules
  • * IBM Storwize V7000 Gen2 - Capacity up to 4 PB and the capability to virtualize external storage
  • * IBM Storwize V7000 – Capacity up to 1.92 PB and the capability to virtualize external storage
  • * IBM Storwize V7000 Unified – provides file connectivity
  • Midrange line:
  • * IBM Storwize V5100 - Capacity on up to 760 modules and the capability to use FlashCore modules

Each of the above family members run software that is based on a common source codebase, although each has a type specific downloadable package.
In Feb 2020 the Storwize V5000 and V5100 are replaced by the FlashSystem 5000 and 5100 respectively; and the FlashSystem 900 and Storwize V7000 are replaced by the FlashSystem 7200.

Timeline

According to the official availability dates and the days the systems are removed from marketing you can determine the following availability to purchase shown in light green.
The graphics only contains the IBM storage systems starting with 'V',.i.e. V3700, V5000, V5010, V5020, V5030, V5100 and V7000.
These systems vary even beyond their names, therefore the graphics also contains IBM type and model.
All the displayed systems can still get regular service at the end of the timeline.

Architecture

Storwize V7000 provides a very similar architecture to SVC, using the RAID code from the DS8000 to provide internal managed disks and SSD code from the DS8000 for tiered storage.

Features and software

All Storwize systems offer the following features:
  • Command line interface
  • Graphical user interface for easier use, with all functions available
  • Thin Provisioning known as Space Efficient Volumes
  • Volumes can be resized, i.e. expanded or reduced
  • RAID levels 0,1,5,6,10
  • Distributed RAID, i.e. DRAID-5 and DRAID-6
  • FlashCopy provides Snapshots with several combinations of these attributes: multiple, incremental, independent, space-efficient, immediately writable, or cascaded
  • Data Migration: data can be moved between all virtualized storage with no disruption
  • Performance Management using throttling of bandwidth and transactions either by host or by volume
  • supports interactive and non-interactive ssh-login
  • supports several ways of call home and notifications
  • security functions, e.g. audit log, encrypted access
In addition, other Storwize systems offer the following features :
In addition, the Storwize V7000 Unified offered the following features:
Most Storwize systems are intended for certain environments and provide several features, that are not licensed by default.
There are several types of licenses that depend on the chosen model and the subject of the license:
  • licenses per net capacity
  • licenses per enclosures
  • licenses per controller
There are some limitations for each model and each licensed internal code.
These can be read on IBMs web pages. Here are examples for V7000, the V5000 series, and IBM SAN Volume Controller.
In addition, there are more contributors to a working environment. IBM provides this in an interactive interoperabitlity matrix

Supported storage media

As of November 2016, available Storwize media sizes include 2.5" flash SSDs with up to 15.36 TB capacity and 3.5" Nearline-HDDs with up to 10 TB capacity, available for Storwize 5000, 7000 and SAN Volume Controller native attach. IBM Storwize Easy Tier will automatically manage and continually optimize data placement in mixed pools of nearline disks / standard disks / read-intensive Flash and enterprise-grade Flash SSDs, including from virtualized devices.

Hardware

The Storwize family hardware consists of control enclosures and expansion enclosures, connected with wide SAS cables. Each enclosure houses 2.5" or 3.5" drives. The control enclosure contains two independent control units based on SAN Volume Controller technology, which are clustered via an internal network. Each enclosure also includes two power supply units.
