Things to study:
ISCSI commands
dm-mp Linux supports dm_mp multipathing type.
HBAnywhere = Emulex
SANsurfer= Qlogic HBA
SnapDrive = HTTP, HTTPS, RPC
Beneficial uses of VLANs: 1) To isolate iSCSI traffic from LAN/WAN traffic. 2) To isolate management traffic from other IP traffic.
zones should be single initiator
A direct connect topology allows for guaranteed maximum network performance for iSCSI.
iSCSI access lists: control which network interfaces on a storage system that aninitiator can access, and limit the number of network interfaces advertised to a host by the storage system.
Power on order: 1) Network Switches. 2) Disk Shelves. 3) Any Tape Backup Devices. 4) NetApp Controller Heads.
Disable ALUA on igroups connecting using the NetApp DSM.

Brocade Switches
Web Tools : Tool to manage Brocade Switches.
cfgshow : CLI command to display all defined zone information.
configshow : CLI command use to verify configuration.
configshow : CLI command use to verify configuration.
fabricshow : CLI command to display which Brocade switches are connected into a fabric.
supportshow : CLI command to collect detailed diagnostic information from a Brocade FC switch.
switchshow : CLI command to view current nodes connected to the switch
switchshow : CLI command to view current nodes connected to the switch
Cisco Switches
Cisco Fabric Manager : Native GUI switch tool for managing Cisco MDS-Series switches and directors.
show zoneset : CLI command to view all defined zone configuration information.
show zoneset active : CLI command to display currently active zoneset.
show version : CLI command to collect information about the firmware version.
NetApp deduplication (ASIS) is enabled on the volume level.
NetApp Host Utilities Kits perform the following functions: 1) They provide properly set disk and HBA timeout values. 2) They identify and set path priorities for NetApp LUNs.
A LUN can be mapped to an ALUA-enabled igroup and a non-ALUA-enabled igroup.
On ESX 4.0 : Path Selection Policy (PSP) for an MSCS LUN should be set to: MRU (Most recently used).
