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 SSDs.  But a clear leader in the employment of SSDs is to use them as cache, which takes advantage of their incredibly high speeds, while minimizing the cost and hassle of implementation. One of the key design decisions during the early development of VeloBit HyperCache was figuring out the op... (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. Join Brian Garrett, Vice President at the Enterprise Strategy Gro... (more)

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)

SDD Cache: Why is Cache Write Through Good?

Whether ‘tis nobler in the mind to suffer the slings and arrows of your IT manager or to take up cache against a sea of data. With apologies to Bill Shakespeare, the IT Dog is discussing two different cache write policies: write through and write back. Let me take a run at telling you what they are, why they are different and what you need to think about when you decide what policy to use. Cache Write Through This is the easier to explain and understand of the two policies discussed here. Cache write through is like having your cake and eating it too. Data is written into cache ...

Maximize the Advantage of SSD Caching

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.  Relat... (more)
