Agenda Training ObjectivesBasic SAN information – TerminologySAN Infrastructure OverviewLive Demo of SANIntel Confidential2
Training Objectives Why do we need a SAN?Clear understanding of the basics of SANdesignBasic understanding of a SANinfrastructure and designLive DemonstrationIntel Confidential3
Basic SAN TerminologyObjective:Each of you will be familiar with thebuilding blocks of Fiber Based SAN.Intel Confidential4
Why do I need a SAN? What is Clustering?Intel Confidential5
Basic SAN Terminology How does a Cluster attach to a SAN?DAS SCSI, Fiber SAN, ISCSI SANFiber Networks, FDDI 100MBFiber Connector Types GBIC 1GB, SFP 2GB&4GB LCFiber Channel Switch & Fiber Channel HBA( Host Bus Adapter)ISCSI can also be used. Recommend adedicated 1GB network switch with MSExchange or MS SQL and a ISCSI HBA on theTarget and ISCSI Initiator Client Node.Intel Confidential6

Traditional Storage Array1. Adding drives – next they must be grouped together in disk groups by RAID level2. Carving out disk groups based on RAID level3. Laying out data4. Leaving stranded capacity – RAID-5 disk groups can’t access unused capacity fromRAID-1 disk groupsIntel Confidential17
Enterprise Virtual Array1. Adding drives – next they must be grouped together in disk groups2. Carve out the disk group(s) - typically EVAs are configured with only one or twodisk groups3. Lay out the data – all RAID-5 and RAID-1 data are sprinkled across all the drivesin the group – EVA disks format on the fly.Intel Confidential18
Adding Disks to the Traditional ArrayR1SP1. Add drives2. Configure disk groups – format disks3. Lay out data – RAID-5 data in RAID-5 LUNs, etc.Intel Confidential19
Adding Disks to the EVA1. Add disks2. Enlarge disk group to include the extra disks3. LUNs are stretched across new disks – data is re-leveled across all disks.Intel Confidential20
