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…

SSD DIMM – An Alternative to PCIe SSD
PCIe Solid State Disks (SSDs) have become extremely popular in a very short amount of time. They provide uncomplicated access to high performance storage, allowing latency problems to be solved where the application is run – on the server. And,…

What To Look For in Server Based SSD
As Storage Switzerland discussed in the article “What is Server Based Solid State Caching” there is much to be gained by moving solid state disk (SSD) closer to the application and its processor. The substantial reduction of network I/O and…

What Are IOPS? and why should you care?
In a recent article, “What is I/O and why should you care”, we discussed what input and output (I/O) operations are and how a storage system’s ability to support these I/Os is a finite resource, one that’s arguably as important…

What is I/O? – And Why Should You Care?
Recording data to a storage device requires two things, a place to put those bytes and a way to get them written to that device. Capacity is the first thing we think of when talking about a storage system, and…

SSD, Heal Thyself!
It is a well known fact that each write takes a toll on the longevity of flash-based solid state storage (SSS), and that each particular module will eventually fail after reaching its write limit. Depending on the memory type that,…
