What is iSCSI?
iSCSI, pronounced eye-skuzzy, is nothing more than a
protocol, a standardized way to talk to IP-based storage
across an IP network. In the context of Bosch’s Video over
IP portfolio, the target is iSCSI RAID storage, and the
initiator could be say a Dinion IP or a VIP X-based encoder
such as the VIP X1 or VIP X1600.
iSCSI combines the latest and greatest from the storage
and communications worlds – SCSI storage (which uses
the SCSI protocol) and the IP network (which uses the
TCP/IP protocol). iSCSI is simply SCSI over IP. iSCSI
stands for IP SCSI.
Until the Internet Engineering Task Force (IETF) invented
iSCSI back in 2002, the main storage protocol was SCSI
(Small Computer Systems Interface). SCSI is still the most
widespread method of communicating with RAID, and is in
fact used by Bosch to connect its NVR server (running
Windows 2003 Server) to a SCSI RAID.
SCSI RAIDs are also commonly used to attach massive
storage directly to DVRs, including Bosch’s own Divar and
DiBos.
