Is PCIe SSD Always Faster?
As Solid State Disk (SSD) has evolved many ways have been developed for it to be accessed by the applications that need performance acceleration. The connection between the application and the SSD is often made by the most available, least…
Achieving Maximum SSD Efficiency
There are two well-known facts about solid state disk (SSD). First, SSD is fast and second, SSD is expensive—compared with traditional disk drives. There are also two well-known facts about the data center. First, almost every data center needs more…

The Big Data Archive
“Big Data” is often thought of as a specialized use case involving machine generated data, typically associated with web search logs, satellite imagery or other sensor data, on which analytics are performed to enable some sort of decision support application.…
How to Track the Cost of Storage Part 2 – lowering TCO
In the first article we opened with a short discussion on why TCO calculations are worth the time they consume. Essentially, any realistic effort to reduce overall costs must start with an accurate baseline of the existing system cost. We…
Your Hypervisor Is Hardware Independent
So Should Your Replication Solution Be Server virtualization changed the way the server infrastructure is deployed, managed and maintained. It also changed the way servers were acquired. No longer was the user locked into a particular set of server hardware…
Advancing The State Of Solid State Caching
Most applications could benefit from a faster infrastructure. Storage performance, especially IOPS, has been routinely identified as a primary impediment to improving compute infrastructure speed. Not surprisingly, customers are turning to Flash Solid State Devices (SSDs) as a solution to…
