I'm participating in the beta but art of the beta agreement is that I can't disclose any info, sorry. Check back here as soon as it is released and we can tell you more about it.

Thanks for this great article!

First of all an important disclaimer: I do not consider myself an IT expert! Still, I developed most parts of the new IT-strategy for our family business (plastics wholesale, 70 employees, 35 users). For about 6 months we've been testing 10 View4 clients on our vSphere hosts.

We found out that our average task worker needs 275 kbits using Dynamics AX 2009 (Axapta) ove the WAN. Switching back and forth to Outlook we saw peaks at around 850-900 kbits!

The values given are for PCoIP and shouldn't come as a big surprise. Teradici as well as WAN optimization vendors claim that a peak bandwith of 1 Mbits should be taken into account for any given PCoIP session.

What might be possible to accomodate on land lines just won't work over mobile networks. Therefore we are currently investigating if our 7 road warriors will get Dynamics AX delivered using ICA. XenApp or XenDesktop, that is the question!

Is there any chance we can expect a better performance from View 4.5? Maybe using some kind of improved bitmap caching?

Regarding the comment about the SAN or VMware dealing with the deduplication of virtual machine disks: Dedupe within Storage Arrays is performance-limiting as all writes need to be compared to existing data (either at time of write or shortly afterwards). I would be amazed if storage-array-dedupe can come close to meeting the IOPS figures you discuss. The current mechanism where VMware View writes the changes to snapshot/difference disks makes a lot of sense and gives good performance with much lower storage costs. What we need now is a change to allow the 'master' copy of the base image for a VM to be kept on a different LUN, so that it can be kept on Solid State Disks – that would really give a great way to improve performance without too much cost.

Hello,
Please I am running with the VMWare 7 on Vista and would like to know how to get the application webs from my host windows.
I installed E-Business Suite R12 on the virtual machine RHEL4 and would like to have access to the link from my Vista machine. I can ping the Virtual machine from Vista, but can't do the same from RHEL4.
Regards,

@Andre I agree that these figures are not for NFS, but they do go for iSCSI SANs that don’t use NFS. There are a lot more considerations for storage of virtual desktops.

If you use linked clones you also need to take into consideration:
- Are you using a virusscanner in your VMs? How is it updating itself?
- Are you using a User Data Disk that stores your profile during usage?
- Do you allow users to install software?
- How is your software distribution handled?
- Is Windows updating itself?
- How often do you do a refresh or recompose?

All these things make it somewhat hard to correctly size for linked clones. Best practice is to observe the growth of the delta files during the testing or Proof of Concept period.
