HP StorageWorks

The HPE Storage (formerly HP StorageWorks) is a portfolio of HPE storage products, includes online storage, nearline storage, storage networking, archiving, de-duplication, and storage software. HP and their predecessor, the Compaq Corporation, has developed some of industry-first storage technologies to simplify network storage. HP is a proponent of converged storage, a storage architecture that combines storage and compute into a single entity.

PolyServe
PolyServe was founded in 2004 by Michael Callahan, serving as chief technology officer, and Carter George, serving as Vice-President, as "a software company in Portland, specializing in database and file serving."

HP, when it bought Compaq, acquired its StorageWorks; HP, when it bought PolyServe, placed its 100+ employees within StorageWorks.

An example of PolyServe's value is that a large British government agency which had 14 idle backup servers
 * dropped the number to two, even though "PolyServe doesn't require the passive nodes, but he maintains them as extra protection" and
 * reduced "failover time from five minutes to 30 seconds .. by 90% the number of users who lose connections during a failover."
