Delivering Storage Virtualization into Private Clouds

“I was first exposed to DataCore at a Brian Madden conference,” said Joseph Stedler, senior engineer and Dallas data center manager, External IT.

Stedler summarizes the value of a storage virtualization approach as follows, “I have worked with traditional SANs for eight years and have had firsthand experience with every major hardware SAN under the sun – EMC, HP, NetApp, etc.” he said. “There are various, major drawbacks to hardware SANs. One is the fact that there is a single point of failure at the disk level. This is particularly the case when doing, for example, firmware upgrades – on the controllers, on the disks, on the shelves – whereby you have to take the SAN down to perform that task. The second most irksome characteristic of hardware SANs is their cost. These EMC SANs, these HP EVAs are inherently expensive, particularly during upgrade time.”

The Value of DataCore: Uptime, Performance and Much More

“There are capabilities that DataCore brings to the table that I absolutely love,” commented Stedler. “The concept of having two SANs as your one SAN environment is just elegantly simple. You have an ‘A’ side and a ‘B’ side.” The beauty of this is that if you need to do hardware maintenance or firmware upgrades, an administrator can actually take down half of the SAN and still have the other half serving production traffic – completely uninterrupted. The second, major benefit of DataCore for External IT has to do with performance. “With DataCore, you will experience enormous performance gains,” noted Stedler. “The performance that DataCore delivers is nothing short of awesome.”
