IBM Storwize systems are virtualizing RAID computer data storage systems with raw storage capacities up to 4PB.[1] Storwize is based on the same software as IBM SAN Volume Controller (SVC).

Models[edit]

The Storwize family offers eight members:[2]

  • IBM SAN Volume Controller – virtualizes multiple storage arrays
  • IBM Flex System V7000 Storage Node – designed for integration with IBM PureSystems (Support withdrawn at SVC v7.3.0)
  • IBM Storwise V7000 Gen2 - Capacity up to 4PB and the capability to virtualize external storage
  • IBM Storwize V7000 – Capacity up to 1.92PB and the capability to virtualize external storage
  • IBM Storwize V7000 Unified – adds file connectivity
  • IBM Storwize V5000 - capacity up to 960TB
  • IBM Storwize V3700 – capacity up to 480TB
  • IBM Storwize V3500 – capacity up to 48TB (available in China, Hong Kong and Taiwan only)

Each of the above family members run software that is based on a common source codebase, although each has a type specific downloadable package.

Architecture[edit]

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.[3]

Features and software[edit]

All Storwize systems offer the following features:[4]

  • Easy to use GUI
  • Space Efficient Volumes also known as Thin Provisioning
  • RAID levels 0,1,5,6,10
  • FlashCopy
  • Data Migration: data can be moved between all virtualized storage (both internal and external) with no disruption

In addition, the Storwize V7000 offers the following features:[5]

  • Peer to Peer Remote Copy
  • Metro Mirror (sync copy)
  • Global Mirror (async copy)
  • Global Mirror with Change Volumes (low bandwidth async copy using flashcopies)
  • External Storage Virtualization
  • Virtual Disk Mirroring
  • Real-time Compression

In addition, the Storwize V7000 Unified offers the following feature:[6]

  • File level storage (NAS)
  • Policy based file placement Active Cloud Engine
  • Global Namespace
  • Async replication on File level

Hardware[edit]

The Storwize family hardware consists of control enclosures and expansion enclosures, connected with wide SAS cables (Four lanes of 6Gbit/s or 12Gbit/s). Each enclosure houses 2.5" or 3.5" drives. The control enclosure contains two independent control units (node canisters) based on SAN Volume Controller technology, which are clustered via an internal network. Each enclosure also includes two power supply units (PSUs).

Storwize V7000 Gen 2[edit]

The IBM Storwize V7000 SFF Control Enclosure Model 524, announced 6th May 2014, features two node canisters and up to 128 GB cache (system total) in a 2U, 19-inch rack mount enclosure. 1 Gb iSCSI connectivity is standard, with options for 8 Gb FC and 10 Gb iSCSI/FCoE connectivity. It holds up to twenty-four 2.5-inch SAS drives and supports the attachment of up to 20 Storwize V7000 expansion enclosures.

IBM Storwize V7000 next-generation models offer increased performance and connectivity, integrated compression acceleration, and additional scalability with the following features:

  • Two node canisters, each with an eight-core processor and integrated hardware-assisted compression acceleration
  • 64 GB cache (per I/O group) standard, with optional 128 GB cache per I/O group (node pair) for Real-time Compression workloads

  • 12 Gb SAS expansion enclosures supporting twelve 3.5-inch large form factor (LFF) or twenty-four 2.5-inch small form factor (SFF) drives
  • Scaling for up to 504 drives per I/O group with the attachment of 20 Storwize V7000 expansion enclosures and up to 1,056 drives in a four-way clustered configuration
  • The ability to be added into existing clustered systems with previous generation Storwize V7000 systems
  • Compatibility with IBM Storwize V7000 Unified File Modules for unified storage capability
  • All models are delivered in a 2U, 19-inch rack mount enclosure and include a three-year warranty with customer replaceable unit (CRU) and on-site service. Optional warranty service upgrades are available for enhanced levels of warranty service.
