Refer to the Exhibit.
What does the graph in the exhibit indicate?
A.
The average amount of read and write latency from the ESXi host to the SAN.
B.
The average amount of read and write latency from the guest operating system to the virtual machine virtual disk file.
C.
The average amount of read and write latency from the ESXi host to the datastore.
D.
The average amount of read and write latency from the cluster to the datastore.
This has to be A. The Object name is the network address authority. If it was to the datastore it would have the datastore name.
well, the term SAN is vague. It includes switched, etc. You can’t really measure the latency to the SAN, rather to the storage. So I think “C” still sounds better.
Frustrating that questions like this make it to the tests.
Check the tab , it’s from Host .
C is correct.
Raj,
Would you please explain, why the answer is C not A. The object name doesn’t show Datastore name, it shows a NAA Path ID.
Thanks in advance.
maybe this device is a iscsi lun, not coming from a SAN network ?
maybe like this:
naa means a HBA card but a HBA card could connect to san or iscsi:
http://en.wikipedia.org/wiki/ISCSI
so naa* means host connected to a san or iscsi of datastore. Either is possible.
There can be multiple datastores per SAN. The naa… number is a path to a single datastore.
