File System Alignment for SSDs There are many techniques and methods that can be used to tune an IT system to improve overall system performance.  SSD caching is widely being used as a low cost, easy to implement method to quickly increase performance with little or no impact on existing operations.  One thing that needs to be considered when choosing SSD caching is how to configure a file system to maximize the performance increase SSD caching provides. Operating Systems and Block Size In the past few years, the sector size of HDDs has increased from 512 bytes to 4k bytes.  Relatively new operating systems (e.g. Windows Server 2008 R2 to present) have evolved to work with this not-so-new sector size to take advantage of higher density drives.  Problems, however, can occur for older operating systems that were not designed to work with the larger block size devices. ...

Challenges with SSD Caching: What Challenges?

George Crump from Storage Switzerland recently wrote an article, arguing that it is better to deploy SSDs in a storage array instead of as a server cache.  The article was sponsored by Pure Storage which happens to sell SSD based storage arrays. George identifies challenges with SSD caching and tiering solutions. While some of the topics he raised in the article are valid, he does not present all sides of these topics.  As a result, the article contains positions that overstate the magnitude of the problems and may lead the reader to the wrong conclusion. I would like to present ... (more)

The Many Places You Can Go with SSD Caching Software

Disruptive technology is a term used to describe an idea or invention that typically disrupts an existing market, often completely displacing an earlier technology.  Sometimes disruptive is great (e.g. digital cameras and cell phones), and sometimes disruptive is not so great (e.g. laser video disks).  SSDs are a disruptive technology in that they are clearly changing the enterprise storage market.  The verdict is still out on just how disruptive SSDs will be; as is the case with many disruptive technologies, it is going to take some time to figure out exactly what to do with SSD...

Using RAM in SSD Caching

Dr Dog Says “You Need More RAM In Your Cache Diet” Well, I am not really a doctor, but I play one on TV. You may remember (if you are old enough) that line from the 1986 Vicks-44 TV commercial.  Anyway, while I may not be a real doctor, I can certainly tell you about why you need more RAM in you cache diet. “I Think My Cache Diet Is Great” If you were happily running your IT system but needed some additional performance, chances are you turned to some kind of SSD caching solution to improve performance at a lower cost point than adding more servers or storage. You went on what I a... (more)

How to Successfully Deploy SSD in the Enterprise

Register > Solid State Disk (SSD) technology is one of the hottest IT areas in 2012. The promise to eliminate storage IO bottlenecks and increase application performance, enable server virtualization, enable data center growth, and reduce IT costs has prompted 83% of all IT departments to consider SSD. But those planning an SSD deployment face a variety of deployment choices. Moreover, choosing poorly can yield large expense, disruption to existing IT environments, and a complex new set of storage management tasks.
