5
Basic <strong>SAN</strong> Terminology<br />
How does a Cluster attach to a <strong>SAN</strong>?<br />
DAS SCSI, Fiber <strong>SAN</strong>, ISCSI <strong>SAN</strong><br />
Fiber Networks, FDDI 100MB<br />
Fiber Connector Types GBIC 1GB, SFP 2GB<br />
&4GB LC<br />
Fiber Channel Switch & Fiber Channel HBA<br />
( Host Bus Adapter)<br />
ISCSI can also be used. Recommend a<br />
dedicated 1GB network switch with MS<br />
Exchange or MS SQL and a ISCSI HBA on the<br />
Target and ISCSI Initiator Client Node.<br />

Traditional Storage Array<br />
1. Adding drives – next they must be <strong>group</strong>ed together in disk <strong>group</strong>s by RAID level<br />
2. Carving out disk <strong>group</strong>s based on RAID level<br />
3. Laying out data<br />
4. Leaving stranded capacity – RAID-5 disk <strong>group</strong>s can’t access unused capacity from<br />
RAID-1 disk <strong>group</strong>s<br />
Intel Confidential<br />
17
Enterprise Virtual Array<br />
1. Adding drives – next they must be <strong>group</strong>ed together in disk <strong>group</strong>s<br />
2. Carve out the disk <strong>group</strong>(s) - typically EVAs are configured with only one or two<br />
disk <strong>group</strong>s<br />
3. Lay out the data – all RAID-5 and RAID-1 data are sprinkled across all the drives<br />
in the <strong>group</strong> – EVA disks format on the fly.<br />
Intel Confidential<br />
18
Adding Disks to the Traditional Array<br />
R1<br />
1. Add drives<br />
2. Configure disk <strong>group</strong>s – format disks<br />
3. Lay out data – RAID-5 data in RAID-5 LUNs, etc.<br />
S<br />

19
Adding Disks to the EVA<br />
1. Add disks<br />
2. Enlarge disk <strong>group</strong> to include the extra disks<br />
3. LUNs are stretched across new disks – data is re-leveled across all disks.<br />
