VMware Horizon View 6 – Impact of VCAI

View Composer Array Integration with Native NFS Snapshot Technology (VAAI) started off at tech preview in View 5.1 but now is fully supported. Below highlights the impact of not having VCAI support if you’re using View Composer in your environment to deploy desktops.

Nutanix supports VCAI

Everything on the lefthand of the line is a result of not having VCAI support. Your golden image has to be copied over to recreate the new replica image as thevbase for the new desktops. Over 11,000 IOPS are used in this example and over 700 MBps of bandwidth consumed. Then times this by how many golden images your team is supported plus the extra time it takes to create the copy the image over. There is also impact to users that have to work during the maintenance period.

If you’re using VCAI your deployment journey would begin to the right of the line. Nutanix fully supports VCAI and also can give the ability to deploy full clones without View Composer.

45 minutes to deploy 400 desktops with VCAI
400-vcai-45min
Time is saved by not having to do the full copy and VCAI does provide better caching of reads on Nutanix as well. Without VCAI it would have been north of 50 minutes and the performance tier would have be used instead of keeping it to deliver great user experience.

What to see this in action at VMworld? Stop by the both 1535 for a demo.

Comments

  1. shadow vm is enabled on cluster or without this features?

    • With VCAI you don’t need to enable shadow clones since every copy is a full clone, THe base image doesn’t become the bottle neck.

  2. Hi

    Can you Say what would be the difference by making linked clones with vs without VAAI\VCAI ? (in time of creation and network utilization)

    Obviously that there is a huge difference with full clones

Trackbacks

  1. […] Any Horizon View Admin at some point has probably had to deal with a View Composer issue at some point(same is probably true for MCS). Maybe the database gets out of sync with vCenter, the View Composer credentials gets unknowing changed or someone deletesmoves the computer account of your golden images. Using Nutanix VMCaliber Clones 400 Full Clone desktops can be created in 49 Min! Only 4 more minutes than using View Composer with VCAI […]
