CCSI earned its original rack mount “bona fides” building 4U rack servers. Read about CCSI history, and you will see that the original rack mounted PC was in the 4U form factor. This was principally a result of the adaptation of the then “state of the art” IBM PC AT desk top computer, to a rack mounted configuration. While 4U was the original “standard” for a rack-mounted computer, it has become less popular over the years as server motherboards have more integrated features, thus requiring fewer expansion slots. 4RU, which is 7.0 inches of vertical rack space, allows us to build a Storage Server with as many as 24 Hot Swappable 3.5 inch hard drives or up to 48 Hot Swappable 2.5 inch hard drives. You can have a mind boggling amount of storage in those 7 inches, up to 48 terabytes when built with 2 terabyte 3.5” hard drives, and up to 31.2 terabytes when built with 2.5” hard drives. CCSI 4U Storage Servers are the right choice for those who need more hard drive capacity than a 3U system supports. We build our 4U Storage Servers with SATA drives for lower cost servers, SAS drives for higher performance servers, and solid state disks for the utmost performance servers. Common applications include enterprise storage servers, DVR servers for video surveillance, medical imaging servers, virtual tape libraries, near-line storage servers, digital content delivery servers, and NAS or iSCSI SAN servers. CCSI 4U Storage Servers are available with nearly any Intel or AMD processor, single or dual or even quad processors. We offer Core™ 2 Duo servers, Core™ 2 Quad , Socket 1156 or Socket 1366 Core™ i7 servers, dual processor and quad processor, dual core, quad core or six core Socket 1207 AMD Opteron™ servers and Socket 1366 dual processor quad core Intel Xeon™ Storage Servers. Storage Servers, especially as large as 4U, are not purchased for energy conserving characteristics; however, power supplies with 80% or higher efficiency rating coupled with low wattage CPUs can be utilized in many of these servers to minimize environmental impact while maximizing storage capacity in the server.
