Module 6: Storage Lesson 4: VMFS Datastores Flashcards
(15 cards)
What is the maximum size of a VMFS datastore?
64TB
A RDM cannot be stored on a ______ datastore, it must be located on a ______ datastore.
A RDM cannot be stored on a NFS datastore, it must be located on a VMFS datastore.
What kind of storage would you use if virtual machine is using SAN snapshot applications?
RDM
What kind of storage would you use if a virtual machine is clustered with a physical machine using MSCS?
RDM
What kind of storage would you use if you want to keep the virtual machine’s data on a raw disk instead of converting it to a virtual disk because, for example, the data disk is very large?
RDM
What two methods can be used to resolve insufficient disk space?
Add an extent to the VMFS datastore or expand the VMFS datastore
When adding an extent to the datastore, how many LUNs can be added?
32 LUNs each up to 2TB
A LUN can be expanded _____ _____ _____ ____, up to _____/
A LUN can be expanded any number of times, up to 2TB
What must you do when you expand an RDM’s underlying raw LUN on the array?
You have to remove the RDM and re-create it
When you add an extent where is the metadata for the entire extent set stored?
In the first extent
What must you do to set up multipathing for iSCSI?
Set up multiple VMkernel ports to use for iSCSI traffic
What are the three multipathing policies that are supported?
Fixed, Round-Robin or Most Recently Used
What is responsible for managing multiple storage paths?
The Pluggable Storage Architecture (PSA) a VMkernel layer
What is the PSA?
A collection of VMkernel APIs that allow third-party vendors to insert code
What is the default plug-in that is provided for multipathing?
Native Multipathing Plug-in (NMP)
