What is Serial Storage Architecture (SSA)?

What does SSA stand for?

Serial Storage Architecture (SSA) is an open Protocol used to facilitate high-pace statistics Switch among disks, clusters, and Servers. SSA is an enterprise and person supported storage Interface technology.

The SSA concept turned into evolved via the IBM Engineer Ian Judd in the early Nineteen Nineties. IBM developed numerous SSA products, including Disk Enclosures, garage servers, and Host Bus Adapters. SSA merchandise are primarily based at the Small Computer System Interface (SCSI) general.

What Does Serial Storage Architecture Mean?

Applications like e-trade, video on-call for, and Video Conferencing are Swiftly advancing, because of improved Network Infrastructures and Computer processing speeds. Such applications use Networks to accommodate facts requirements and require structures with sufficient Storage Capacity, Fault Tolerance, and high Data Bandwidth.

To meet increasing garage machine needs, the SSA standard was developed for Deployment in Mainframe environments, networked Computer Systems, and small sySTEMs. SSA affords excessive-overall perFormance Serial Attached Technology (SAT) to link Disk Drives and servers.

SSA is configured with two factor-to-point Hyperlinks related thru the ports of special gadgets. A Node, inclusive of a garage tool with two ports, connects to 2 different Storage Devices the usage of two link pairs. If every garage Device has two ports, they are easily linked as an SSA Loop. SSA Configuration provides 20 MBps of hyperlink bandwidth and helps general information bandwidth of eighty MBps.

SSA blessings encompass:

• Enables spatial reuse due to the fact hyperlinks do not intervene with adJoining nodes.
• Supports simultaneous full-Duplex information transmission.
• Provides Data Security thru fault tolerance.
• Supports hot swapPing of tough drives.
• Detects disruptions and mechanically resets systems with out connection disruption.
