Computer servers for business or industrial usage. Typically these systems have redundant components, extra upgrade capacity, high performance characteristics, hot-swappable components (such as SCSI hard drives and power supplies) and optional rack mountability.
For example:
Dell PowerEdge Servers
HP Proliant Servers
Compaq Proliant Servers
IBM Netfinity Servers
IBM eServer xSeries Servers
Dell PERC H710 Mini Mono 342-3534 SAS Integrated RAID Controller 512MB NV Cache - Brand New
This controller is designed to work in the dedicated proprietary expansion slot on the PowerEdge servers and WILL NOT fit the standard PCIe expansion slot.
