IBM Scale Out Network Attached Storage 1.3.0

IBM Scale Out Network Attached Storage (SONAS) V1.3.0 enhancements:

  • High performance backups through Network Data Management Protocol (NDMP) Version 4 and multiple stream support
  • Anti-virus scanning capability for files accessed via the Common Internet File System (CIFS) network file protocol
  • Inclusion of General Parallel File System (GPFS™) V3.4 into the SONAS software stack
  • Service improvements including new repair menus, call home improvements, and remote support
  • Snapshot management
  • File level clones
  • Support for independent filesets which include:
    • Fileset level snapshots
    • Fileset level user and group quotas

IBM Scale Out Network Attached Storage (SONAS) is a scale-out NAS offering designed to provide a clustered NAS system with a single name space for CIFS, NFS, HTTPS, SCP, and FTP services. The system consists of:

  • Two to thirty-two Interface Nodes (2851-SI2)
  • One to thirty storage pods consisting of Storage Node (2851-SS2), Storage Controller (2851-DR1), and attached disks
  • Disk Storage Expansion units (2851-DE1)
  • Ethernet and InfiniBand switches and racks

The maximum configuration provides up to 21.6 PB of storage capacity in a single cluster, highly redundant system. The storage used in the SONAS system can be high-performance 15K/10K RPM SAS HDDs or high-capacity 7.2K RPM Nearline SAS HDDs, allowing configuration according to needs.

The management function provides a central point for the system administrator to configure, monitor and manage the system. The management function supports both a browser-based GUI and CLI. With SONAS 1.3, the management function resides on an interface node (2851-SI2) within the SONAS system. One interface node is designated as having the active management role and another interface node is designated as having a passive management role. New SONAS 1.3 systems no longer have a dedicated SONAS management node (2851-SM1) and the existing SONAS Management Node (2851-SM1) is being withdrawn from marketing. Refer to Withdrawal Announcement ZG11-0299, dated October 11, 2011.

The Interface Node provides the network port connection and the file services for the IBM SONAS system. These nodes can have optional multiple 10Gb Converged Network Adapters and they prove extremely fast access to data. These interface nodes are connected to the rest of the SONAS system via a redundant high-speed InfiniBand data network.

The IBM SONAS system has the concept of a storage pod. Each storage pod consists of a pair of Storage Nodes and one or two Storage Controllers. Each Storage Controller contains 60 disks, and can have one Disk Storage Expansion unit attached for 60 additional disks per controller. Each storage pod supports a maximum of 240 hard disk drives. A maximum of 30 storage pods are supported for a maximum of 7,200 hard disk drives in a single system.

These systems are configured within three pre-defined, customizable rack configurations. The Base rack (2851-RXA) contains the InfiniBand switches, some Interface Nodes, and up to one storage pod. Each Storage Expansion rack (2851-RXB) contains up to two storage pods, for a maximum of 480 disks. The Interface Expansion Rack (2851-RXC) contains up to 20 additional Interface Nodes.

IBM SONAS 1.3 provides support for the following new hardware features:

  • 3 TB 7.2K RPM Nearline SAS disk drives in the SONAS storage controller (2851-DR1) and disk storage expansion unit (2851-DE1)
  • 900 GB 10K RPM SAS disk drives in the SONAS storage controller (2851-DR1) and disk storage expansion unit (2851-DE1)
  • Networking Patch Panel (feature code 0110) on the SONAS Base Rack (2851-RXA) and SONAS Interface Expansion Rack (2851-RXC)
  • Patch panel insert (6x1Gb and 2x10Gb) for the Networking Patch Panel (feature code 0111)
  • Patch panel insert (4x1Gb and 4x10Gb) for the Networking Patch Panel (feature code 0112).
