4 minute readNetApp Flash Cache and SSD Drives: The Secret to More Capacity
All the buzz these days is around flash storage. Is flash the future? Will everyone eventually have all-flash arrays.
What I’m about to share below may be the difference between just getting by and actually thriving in your IT environment.
One of the advantages of working at Reliant Technology is that we have a creative, dynamic group of individuals who all work together to come up with resourceful and ingenious solutions for our customers. The other day my colleague, Brad, approached me and said the following: “Kyle, I keep talking to all these IT directors and storage admins who talk about flash as though it’s an all or nothing deal. They think they either have to do a refresh of their entire environment – which they can’t afford – or else stay stuck with those magnetic tape drives from the 70s.”
I looked at him, rolled up my sleeves, stroked my beard and pondered my response. Surely, not everyone believes this. There has to be a better way. I squinted into the springtime Georgia sun, picked up a magnolia leaf and pondered how I might respond.
Here is my response, a symphony of sorts, in three movements:
Movement #1: Performance Acceleration Modules
Hear this from the beginning. I’m not talking about anything new here. NetApp PAM was introduced by NetApp back in 2008. So why am I talking about it now? Good question. Well, in response to the dilemma above, it is possible to gain some of the benefits of flash storage right now without having to overhaul your storage environment. In essence, the PAM offers a new way to optimize the performance of a NetApp storage system by improving throughput and latency while reducing the number of disk spindles or shelves required. It also reduces power, cooling and rack space requirements. So, if you’re feeling a little claustrophobic and want to do some spring-cleaning, perhaps a PAM card might give you some much needed breathing room. Ahhhhh, smell that fresh air.
Movement #2: NetApp Flash Cache Intelligent Caching
At this point, you can literally hear the music swell as the sound of all that clear air provides a resounding reverberation of acoustic bliss off the walls of your now sizeable server space. NetApp Flash Cache is basically a method whereby your NetApp system intelligently determines and caches user data or NetApp metadata based on usage. This means no setup or ongoing administration for users, freeing up your time to focus on new projects. According to NetApp, Flash Cache works with all NetApp storage protocols and software and can increase your I/O throughput by up to 75%. Boom! The cymbals clash! At this point, you might be hearing Ralph Vaughan Williams Symphony No. 6 in E minor, 2nd movement of course.
Movement #3: Solid State Drives
While we all love to hear our symphony on analog, tape drives just aren’t cutting it any more. Tape is for the past. It is time for that dream to die. Haight-Ashbury was a long time ago. To get real speed you have to get some SSD drives! It’s the easiest way to upgrade your current system and get the speed and capacity you want!
