An HBA (Host Bus Adapter) Is commonly used fore which protocol?
FC
Name one of the more common File Systems that a NIC (network interface card) is
used with?
NFS (Network File System)
What is the primary benefit of blade servers?
High density
What type of server is optimized for density?
Blade server
When a write from a SAN host is received, where is it first written?
NVRAM
,When booting a Host from FC SAN, what's one of the things you should keep in
mind?
Each host has to have its own LUN
Name some protocols commonly used in SAN block.
iSCSI, FC and FCoE (or oF)
What must be done in a FC SAN environment for a host to see a storage LUN?
WWN zoning or port zoning
A host connected through FC SAN, suddenly loses access to multiple volumes.
Where should you first start troubleshooting?
Layer 1 (cable and SFP)
What is gained from configuring Multipath on a host?
Link reliability to the LUN is improved
What's one thing you can do to improve FC throughput?
Increase transmission speeds by adding faster HBAs and optics. (upgrade 8Gb to
16Gb)
, What's one thing you could do to increase iSCSI throughput?
Install a faster switch
Can a SAN storage LUN be shared and written to by multiple initiators without
data corruption?
Yes, One of the major features of File and object are to share the same LUN to
multiple hosts.
FC is primarily used for...
Block storage (system access)
Managed ETH switches are more appropriate for...
VLAN configurations
Unmanaged ETH switches have featured...
Plug'n'play DSCP
What's the most commonly used transmitter in FC?
SFP and SFP+
