IBM Storage

The IBM Storage product portfolio includes disk, tape, NAS and Flash storage products, storage software and integrated solutions. On June 4, 2012, IBM announced a strategic approach to storage referred to as "Smarter Storage."[1] IBM has three basic tenets for Smarter Storage: efficient by design, self-optimizing, and cloud agile.[2]

Disk Systems

Systems for enterprise workloads

XIV

The IBM XIV Storage System is a high-end disk storage system designed to provide consistent performance, high availability and simple usability. As virtualized storage that meshes tightly with server hypervisors, XIV is designed to work well in cloud and virtualized environments. The XIV Gen3 model offers 3 TB drives, providing up to 243 TB of usable capacity per rack. SSD caching (available as an option) adds up to 6 TB of management-free high-performance data caching capability to the whole array. The system also can connect to external storage via Fibre Channel (8Gbit/s) and iSCSi (1 or 10 Gbit/s).[9]

SONAS

IBM Scale Out Network Attached Storage (SONAS) is the IBM enterprise storage platform based on GPFS technology. This system implements NAS based protocols over a large-scale global name space. Today the system can scale out using commodity components to 30 balanced nodes and up to 14.4 PB of storage. GPFS gives the SONAS system with built-in ILM and tight integration with Tivoli Storage Manager helps move data to disk pools.[10]

For entry and midrange workloads

Other storage products and capabilities

SAN Volume Controller

The IBM SAN Volume Controller (SVC) is a block storage virtualization appliance. Because the IBM Storwize V7000 uses SVC code, it can also be used to perform storage virtualization in exactly the same way as the 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) than perform sub-LUN automatic tiering (EasyTier).

SmartCloud Storage Access

IBM SmartCloud Storage Access is a software solution designed to create a private cloud storage service on existing storage devices. The software can be configured to allow users self-service, Internet-based access for account creation, storage provisioning and file management. The software offers simple management with monitoring and reporting capabilities, including storage usage by user and group definitions.[44]

Real-time Compression Appliances

The IBM Real-time Compression Appliances are designed to compress active primary NAS storage by up to 80 percent with no performance degradation and with no IT or application changes.[45]

  • STN7800 – The STN7800 is a 2U rack-mounted appliance, equipped with 1-gigabit copper Ethernet ports, 10-gigabit optical Ethernet (10GBASE-SR)ports, or both configured as:
    • Four 10-GbE optical ports and eight 1-GbE copper ports
    • Eight 10-GbE optical ports
    • Sixteen 1-GbE copper ports[46]
  • STN6500 - The STN6500 is a 2U rack-mounted appliance, equipped with 16 one-gigabit copper Ethernet ports and 1 management port. IBM announced that the STN6500 will be withdrawn in March 2013.[47]
  • STN6800 - The STN6800 is a 2U rack-mounted appliance, equipped with 1-gigabit copper Ethernet ports, 10-gigabit optical Ethernet (10GBASE-SR) ports, or both configured as:
    • Four 10-GbE optical ports and eight 1-GbE copper ports
    • Eight 10-GbE optical ports
IBM announced that the STN6800 will be withdrawn in March 2013.[47]

Linear Tape File System (LTFS)

LTFS works in conjunction with LTO tape technology to simplify accessing data stored on an IBM tape cartridge. LTFS 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.[48]

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.

Active Cloud Engine

The Active Cloud Engine (ACE) is an advanced form of multiple site replication. ACE is designed to allow different types of cloud implementations to exchange data dynamically. ACE does is designed to extend the SONAS capability for a single, centrally managed namespace, to a truly distributed, geographically-dispersed, global namespace.[49]

IBM Easy Tier

IBM Easy Tier is designed to automate data placement throughout the disk pool on certain IBM storage systems to improve the efficiency and performance of the storage system. Easy Tier is designed to relocate data (at the extent level) across up to three drive tiers automatically and without disruption to application. Easy Tier also rebalances extents within the same disk tier - even within homogeneous and single-tier extent pools.[50] IBM Easy Tier is available on the DS8000 Series, Storwize V7000, Storwize V7000 Unified, V5000, V3700 and SAN Volume Controller.
