Validate changes made to the VMware environment -- Find and record all VM to all LUNs mapping.
Before VM-aware Navisphere
After VM-aware Navisphere
Generate an ESX device to CLARiiON mapping
report. Then the VMware admin must perform
multiple steps in VCenter to calculate which VM
disks uses which LUN, and put the two reports
together side by side. They could also maintain
updated Excel spreadsheets for this mapping
information.
Assuming 10 ESX servers each containing 10 VMs,
this procedure would require almost 500 clicks
using both Navisphere Manager and vCenter
Generate an end-to-end mapping of VM disk to
CLARiiON LUN report. This report lists all VM-to-
LUN mappings, and you can examine existing VM
storage allocation. The tree view in this report
shows the vMotion storage and vMotion changes.
You can also use this report to perform VM storage
planning for performance, security compliance, and
high availability.
Assuming 10 ESX servers each containing 10 VMs,
this procedure would require 10 clicks using both
Navisphere Manager
Capacity Planning (For ESX 4.0 and ESX 4i) -- Determine how much storage has been
overcommitted and used by VMs for a given LUN to ensure VMs don’t run out of space.
Before VM-aware Navisphere
After VM-aware Navisphere
If multiple virtual disks with a thin virtual disk
option are created on a given LUN, you must go
through each virtual machine and find its capacity
allocation.
First, in Navisphere, you need to find the VMware
ESX server and ESX device name for the given
LUN in Navisphere. Then, in the VMware Client
GUI, find the datastore with this ESX device name,
if any. For each datastore (VMFS), find all the VMs
using this datastore, and find the LUN usages and
capacity allocation for hard disks in each VM. Also,
you need to browse the VMFS datastore to
determine the consumed capacity of the virtual
disks on a given datastore.
Assuming 10 ESX servers each containing 10 VMs,
this procedure would require almost 60 clicks using
both Navisphere Manager and vCenter.
In Navisphere, you can simply search for the LUN
by name to see what ESX servers and VMs (hard
disks) are affected in the LUN Properties dialog
box. By expanding and selecting all VMs, you can
figure out the total promised space to the VMs on
this LUN and the total committed space by the VMs
on this LUN.
Note: If you need information about all VMs
overcommitted for all LUNs, use the VM-aware
Navisphere interface to run two (LUN and virtual
machine) reports.
Assuming 10 ESX servers each containing 10 VMs,
this procedure would require 15 clicks using
Navisphere Manager.
EMC Storage Viewer
EMC Storage Viewer is a feature for managing EMC storage devices (Symmetrix and CLARiiON) and
storage systems within the VMware vCenter management interface.
The following are requirements for running EMC Storage Viewer in CLARiiON environments:
Install Solutions Enabler software
Ensure you have a license file for Solutions Enabler
EMC CLARiiON Integration with
VMware ESX Server
