RAID
 R – Redundant
 A – Array
 I – Inexpensive (or Independent)
 D – Disks
Types of RAID
 RAID 0 "Stripe Set"
 RAID 1 "Mirror"
 RAID 3 & 4 "Stripe Set dedicated parity"
 RAID 5 "Stripe Set distributed parity"
 RAID 6 "Stripe Set dual distributed parity"
 RAID 0+1 or RAID 10 "Nested RAID“
 Definition of Parity: If a single drive in the array
fails, data blocks and a parity block from the
working drives can be combined to reconstruct
the missing data.

What is SCSI
 A set of standards
 SCSI most common uses
 Hard Disks, Tape Drive and other Devices

What is Fiber Channel
 a gigabit-speed network technology
primarily used for storage networking
 Fiber Channel signaling can run on both
twisted pair copper wire and fiber-optic
cable
 There are three major Fibre Channel
topologies:
 Point-to-Point
 Arbitrated loop
 Switched fabric
What is iSCSI
 A protocol that allows clients (called
initiators) to send SCSI commands to
SCSI storage devices (targets) on remote
servers.
 Uses TCP/IP (typically TCP port 3260)
 iSCSI needs
 Initiator
 Host Bus Adapter (HBA)
 Target
SAN
 S – Storage
 A – Area
 N – Network
What is a SAN
 An architecture to attach to remote
computer storage devices
 Disk Arrays
 Tape Libraries
 Optical Jukeboxes
 SANs often utilize a Fiber Channel or
iSCSI fabric topology

Microsoft Clustering (MSCS)
 What is a Cluster
 Terminology
 How we are configured here at Grey
What is a Cluster
 Microsoft Cluster Server (MSCS) is




software designed to allow servers to work
together as computer cluster, to provide
failover and increased availability of
applications
Minimum number of nodes in a cluster is 1
Maximum number of nodes in a cluster is
8
Need shared disk San or NAS storage
Windows 2003 Enterprise Server
Terminology
 Node
 Cluster Service
 Quorum
 Resources
 Groups
 Virtual Server
