Once a Bug Killer, Now a Killer Setup

Not everyone enjoys or has the benefit of taking what they learn at work to apply at home in personal situations, but I consider myself lucky because the things I learn from work can often be very useful for hobbies in my own time. As an electronics and PC gaming fanatic, I always enjoy tips that would increase the performance of my technological equipment. Common among PC gaming enthusiasts is the obsession with making their gaming rig excel in every aspect by upgrading video card, ram, processor, etc. Before working at SoftLayer, I had only considered buying better hardware to improve performance but never really looked into the advantages of different types of setups for a computer.

This new area of exploration for me started shortly after my first days at SoftLayer when I was introduced to RAID (Redundant Array of Inexpensive Disks) for our servers. In the past, I had heard mention of the term but never had any idea of what that entailed and was only familiar with our good ole bug killer brand Raid. You can imagine my excitement as I learned more about its intricacies and how the different types of RAID could benefit my computer’s performance.

Armed with this new knowledge, I was determined to reconfigure my gaming pc at home to reap the benefits. Upon looking at the different RAID setups, I decided to go with a RAID 0 because I did not want to sacrifice storage space and my data was not critical enough that I would need a mirror such as provided with RAID 1.

One thing led to another as I became occupied for a good amount of time with benchmarking drive performance in my old setup versus my new setup. In the end, I was happy to report a significant performance gain in what I now refer to as my “killer setup”. Applications would launch noticeably faster and even in games where videos were stored locally on hard drives, the cinematic scenes would come up faster than before.

To add to the hype, a coworker was also building a new computer in anticipation of a new game called Final Fantasy XIV. It felt like a competition to exceed each other with better scores. I’m already planning ahead for future upgrades since this time around I had only used SATA drives. For my next upgrade I would love to run a RAID 0 with two SSD drives to see what kind of boost I would get.

So for business or pleasure, have you ever considered the benefits of setting up a RAID system?

Solid State Drives – In House Performance Stats

I love working at SoftLayer. I get to play with the newest hardware before anyone else. Intel, Adaptec, Supermicro… The list goes on. If they are going to release something new, we get to play with it first. I also like progression. Speed, size, performance, reliability; I like new products and technologies that make big jumps in these areas. I am always looking to push components and complete systems to the limits.

But alas, Thomas Norris stole my thunder! Check out his article “SSD: A Peek into the Future” for the complete skinny on the SSD’s we use. I seem to be a bit to concise for a nice long blog anyways. But not to worry, I’ve got some nifty numbers that will blow the jam out of your toes!

Solid State Drives (SSD) represent a large jump in drive performance. Not to mention smaller physical size, lower power consumption, and lower heat emissions. The majority of drive activity is random read/write. SSD drives have drastically improved in this area compared to mechanical drives. This results in a drastic overall performance increase for SSD drives.

This is a comparison of the Intel 32GB X25-E Extreme drive vs. other drives we carry. Note the massive jump in the random read/write speed of the SSD drive.

No more waiting on physical R/W heads to move around. How archaic!

Chart

Please note that no performance utility should be used to definitively judge a component or system. In the end, only real time usage is the final judge. But performance tests can give you a good idea of how a component or system compares to others.

Single drive performance increases directly translate into big improvements for RAID configurations as well. I have compared two of our fastest SATA and SAS four drive RAID 10 setups to a four drive SSD RAID 10 using an Adaptec 5405 Controller.

Chart

The Adaptec 5405 RAID controller certainly plays a part in the performance increase, on top on the simple speed doubling due to 2 drives being read simultaneously. (See my future blog on the basics or RAID levels, or check Wikipedia) .

Propeller heads read on:

The numbers indicate a multiplied increase if you take the base drive speed (Cheetah – 11.7mbps / X25-E – 64.8mbps) and double it (the theoretical increase a RAID 10 would give): 23.4mbps and 129.6mbps respectively. Actually performance tests show 27.3mbps and 208.1mbps. That means the Cheetahs are getting a 15% performance boost on random read/write and the X25-E a whopping 37% due to the RAID card. Hooray for math!

Once again, this is all performance tests and a bit of math speculation. The only real measure of performance, IMO, is how it performs the job you need it to do.
