Today’s workloads are dealing with more and more data with the expectation that it will be available almost instantly. A tall order for even the most experienced administrators. Applications can be tuned, SAN drives replaced for faster 15K disks, upgrade our SAN switches, and we can only install so much RAM in our servers. Where does this leave those of us looking for faster data access? Enter VMware Virtual Flash.
VMware Virtual Flash is a newly available feature in vSphere 5.5 which takes advantage of Solid State Disks (SSDs) that are locally installed on your servers. Applications that require low latency data access, which were previously not good virtualization candidates, can now be placed onto your ESXi servers and reap the benefits of why you went with virtualization in the first place.
1. Provides up to 4TB of flash based cache storage.
2. Transparent to the operating system and the application (no need for special software in the VM).
3. Works with vSphere HA, vSphere DRS, & vSphere vMotion.
4. Can be configured per VM disk.
5. Reduce traffic on your SAN network.
Dell servers are a great match for VMware’s Virtual Flash capabilities. Dell R620, R720, R820, R920, M620, M820, T620 all have PCIe based SSD options for super-high speed I/O.
You can see below the implications of choosing Dell PCIe based SSD’s over the traditional hard drive configurations that you would see on a physical server.
With a potential 1.8GB/s sequential read and 1.2GB/s sequential write speed, it’s a “no-brainer” to bring the superior SSD capabilities of Dell servers together with VMware’s new Virtual Flash feature set. So if your organization is in need of better performing virtualization hosts or you are looking to bring that once “not virtualization friendly” application into your VMware environment we encourage you to start a conversation with us.
