Serial Storage Architecture (SSA)

Serial storage architecture (SSA) offers high-speed data, application and software access within large-capacity storage platforms. SSA was once most used at the enterprise level for large networks and infrastructures, as it allowed for speedy searches and quick deployment. SSAs made it possible to connect numerous tangential components within an entity’s storage area network (SAN) so that they would be visible and usable through an entire server or server farm.

Using SSA requires serialization of hardware in order to connect components such as host adapters, hard-disk drives (HDDs) and other peripheral modules or devices.

Setting up SSA and using it in growing enterprise environments

To create the agility of public cloud within your private enterprise cloud, you will need to provision infrastructure and network architecture unique to your data center(s). In a small seedling venture quickly growing into an enterprise-level operation, SSA was at one time an ideal option, and worked well as a way to evolve away from small computer system interfaces (SCSIs).

During the heyday of SSA, you could use it a way to replace an existing SCSI. It was able to easily use your current command set to map and upgrade to SSA, which allowed you to set up communication between the devices of your infrastructure and network. Scalability was one of the preferred advantages of SSA, because it allowed open systems and almost any type of computing environment (available in the 1990s and early 2000s) to expand (or shrink). In addition, when SSA was configured within your architecture, it would automatically recognize devices. That meant you could remove or replace HDDs, power supplies, and components on the SAN while everything else stays connected and fully functional without having to power down and back up again.

While SSA is now thought by most to be outmoded by other newer technologies, it was the first storage interfacing system that created a quick and reliable workaround for large companies that could no longer successfully deploy SCSIs.
