Highly Reliable Systems manufactures alternatives to tape backup. We'll be showing our RAIDFrame. The RAIDFrame is 4U rackmount that has five removable cartridges called RAIDPacs. Each RAIDPac cartridge houses 3 standard SATA hard drives, a cooling system, and an in-stream SATA RAID controller. Unlike standard RAID arrays that contain removable, hot-swap hard drives, the RAIDFrame actually has individual removable, hot-swap RAID arrays.
