Storage acceleration features in desktop virtualization

Friends who have had the experience of deploying and implementing VDI (Virtual Desktop architecture) know that VDI has a very high demand for storage performance (it is reported that a virtual desktop costs about 1/5 or more of the cost of storage costs), desktop virtualization has been different from the previous server virtualization, because the number of desktop virtualization is greater, This also leads to higher requirements for storage. such as most small and medium-sized enterprises, the server may only have more than 10, after virtualization, one or two servers can meet the requirements of the operation, storage performance is also more capacity to meet, and most of the enterprise hundreds of desktops, centrally deployed in the data center, the performance requirements for storage naturally self-evident.

In the past IT staff have been repeating this effort to make storage devices faster and more efficient:

1. Increase the number of hard drives, add more high-speed hard disk to share data read and write operations (striped data read and write can increase the performance of storage and response speed, this is RAID 0, such as RAID technology is the main reason)

2. Upgrade Storage network links to multiple faster links (such as dual 8G fiber network, dual storage switches, dual HBA cards, etc.)

3. Buy storage when buying large cache (caching, because the use of RAM technology, so read and write operations, cache efficiency than hard disk efficient) space storage

The above method can increase the performance of storage in the case of comprehensive use, but it will also cause your storage cost to double, and the cost of each virtual desktop can be considered highbrow by the majority of IT staff (usually in the virtual desktop, per virtual machine or per user as the calculated cost unit).

Companies are deterred from making decisions about whether they are large-scale virtual desktops. This is one of the reasons why many companies today are just small-scale, pilot desktop virtualization.

VMware's large number of virtual desktop client deployments are also discovering and realising this problem. Therefore, a large amount of resources are invested to optimize the storage requirements of virtual desktops and reduce the cost of virtual desktops.

During the recent learning process, there was a chance to use VMware's storage acceleration technology specifically for Virtual desktop development. As a hope that virtual desktop rapid development in the domestic technical staff, is very excited.
