Features that are added with Service Pack 1 include: Among the improvements are many of the same updates that were provided to Windows XP users with Service Pack 2. On March 30, 2005, Microsoft released Service Pack 1 for Windows Server 2003. Multi Path IO (MPIO): It provides an alternate connection to IO devices in case the primary path is down.In that case, all processing is done by the OS. In case hardware support is not available, it can use software enabled RAID. Software and Hardware RAID: Windows Storage Server 2003 has intrinsic support for hardware implementation of RAID.There is no need for the storage units to be of the same maker and model. JBOD systems: JBOD ( Just a bunch of discs) systems, by using VDS, can manage a group of individual storage devices as a single unit.Virtual Disc Service: It allows NAS devices, RAID devices and SAN shares to be exposed and managed as if they were normal hard drives.
This increases performance of the Storage network in some scenarios, such as using a database server.
iSCSI uses the SCSI protocol to transfer data as a block of bytes, rather than as a file. Thus a Storage Area Network can be created over the LAN itself. Support for SAN and iSCSI: Computers can connect to a Storage Server over the LAN, and there is no need for a separate fibre channel network.Distributed File System (DFS): DFS allows multiple network shares to be aggregated as a virtual file system.It can be joined to an existing domain as a member server. Windows Storage Server 2003 can be promoted to function as a domain controller however, this edition is not licensed to run directory services.
