SERVER PROFILES
While synthetic workloads do a great job of testing the underlying technology and reporting easy to understand results, they aren’t always indicative of how the drive will be used by the end user. Workloads that simulate enterprise environments try to bridge that gap without being overly complex.
The database profile is 8K transfers, and 67% percent of operations are reads.
For our server profiles, we thought we would mix things up a bit and put an 800GB Intel SSD DC S3700 into the mix. The S3700 has some of the best performance numbers on our server workloads, but its raw specs are less than half the SSD800MM. For the database workload, the SSD800MM came very close to doubling the S3700.
The fileserver profile is based on an 80% read/20% write mix. Its made up of blocksizes from 512 to 64K, each making up a different percentage of the access pattern.
The pattern is: 512 bytes=10%, 1k=5%,2k=5%, 4k=60%, 8k=2%, 16k=4%, 32k=4%, 64k=10%.
With the fileserver workload, the S3700 closed the gap but still came up 33% short.
The webserver profile is similar to the fileserver profile, but has some additional 128K and 512K accesses thrown in for good measure. Additionally, the profile is 100% read.
Once again the SSD800MM nearly doubled the performance of the S3700. We thought that the strength of the Intel controller might make this a closer challenge, but the HGST offering was just too much.
I’ve long been a proponent of running virtualization environments totally under SSDs. This 12G technology should be the convincer. Would have liked to see some RAID 0 benchmarks run with 4 and 8 SSD units. Curious as to how linear the performance gains would be.
This will come in time and obtaining multiple drives for this report was not possible. We always ask as was obvious with our recent Intel and Adaptec/SMART report where we used 24 Optimus SSDs.
Other sites already did 12 gb/s weeks ago! Did you guys miss that?
Oh really? Perhaps you can send us a link or two to a 12Gbps review (not announcement). Thanks ahead.
These are the first that we are aware of.
Tweaktown and storage review have both already done 12Gbs with the true first 12gbs ssd… the toshiba! This isn’t even the first 12gbs ssd.
You are absolutely correct and thanks. Paul snuck one in there while we were on our way to Computex. Thanks for the heads up!
Three weeks ago….
