VMware VSA – ESXi requirements

by FrankBrix in

A cool new feature of vSphere5 is the VMware VSA. It is pretty much a virtual appliance that makes local storage shared storage. 

VMware has just released a VSA Deep Dive document a must read if you are considering this solution. 

Some of the ESXi requirements for VSA is:

  • Host must be installed with ESXi 5.0
  • It must be a greenfield deployment. No existing virtual machines running
  • ESXi and vCenter server must have the same gateway address. They need to be on the same subnet
  • 4 – 6 or 8 spindles is supported
Check out the document to find other requirements.

How to remove a LUN from an ESX host

I have been contacted several times in the last couple of week about the removal of LUNS from an ESX host. In every case the Storage Admin had masked the LUN away from the ESX hosts on the storage array. This is NOT the way to do it. It will result in a APD (all paths down) to the LUN. A side effect will be that hostd will be affected and start disconnecting in vCenter.

ESX 4.x

When removing a LUN from an ESX 4.x host you will need to use the “esxcli” commands. kb 1015084 

ESX 5

When removing from ESX 5 things have gotten a lot easier. Now you can do most from the vSphere Client. Check out the following kb 2004605 

The give away here is: Never just remove a LUN from the SAN that the ESX host has access to. Even though you have removed all virtual machines and nothing is running on it. Before doing anything on the storage array, you will need to detach the LUN from the ESX host.

VMworld is next week and I am sure vSphere 5 will be available for download before the conference. A new version of vSphere also means a new version of the VCP exam. The new exam is available to schedule from Monday 29Th of August.

In this context VMware has just released the VCP5 mock exam. The mock exam consists of 30 questions helping you to prepare for the VCP exam.

For VCP training tips check out my VCP page.

To be able to take the VCP exam you need to 1. Be a VCP4, 2. Have attended an ICM4 course & the vSphere5 whats new, 3. Have attended the ICM5 course.

vRAM Entitlements

VMware has introduced the “vRAM” licensing concept with vSphere 5. The vRAM is the amount of memory you can allocate to your virtual machines running on an ESXi host. If you have a 2 x socket host running Enterprise+ licenses you will be able to allocate 96GB + 96GB = 192GB to your virtual machines. If you on the same host were running Standard licenses you would only be allowed to allocate 32GB + 32GB = 64GB of memory. The table sums of the different vRAM entitlements:

Enterprise+ 96GB
Enterprise 64GB
Standard 32GB
Essentials+ 32GB
Essentials 32GB
Free ESXi 32GB

vSphere5

After more than two years vSphere5 is ready! This will be a great release with many new features.

I look forward to working with Storage DRS, the new Virtual Storage Appliance, VMFS5 etc.

There will also be some changes regarding the licensing. vRAM is the new word. Some customers will need to buy more licenses but I think most will manage with what they have. Pretty much so sum it up Enterprise Plus gives you 48GB RAM pr. license. Take this into account when sizing your servers. a Dual Socket system with 96GB RAM would make sense.
