Raid/Enterprise

Once configured and setup, one thing we did notice was that the device is not NCQ compatible. This results in some abnormally low random access high QD results. In order to provide an accurate representation of the performance of the device we compiled results from two setups with the device itself. The first result will be performance with the HDD …

IOmeter 2008 We ran some IOmeter configurations to test several access patterns on the device. Again, we are looking to compare the differences of the different setups. The Sequential 64mb test is to measure the overall speed with large files, and the 32mb test is to test with medium file sets. As you can see the SSD Alone still shows …

Real World Usage There is a bit of confusing data here. The device benchmarks, so far, show extremely great gains when compared to a HDD used alone. The acceleration over the typical HDD is quite impressive yet it still lacks behind the performance if you were to use the SSD alone. Occasioonally synthetic benchmarks can be a bit misleading. The …

Operating System Load Times Once again we are going to see the performance of real world usage except this time in regards to the amount of time it takes to load the operating system (Win7) using the three different scenarios. The lower time of loading is best. The SSD Alone only slightly outperforms the SSD/HDD combo inside of the HyBrid …

Today we are going to take an in-depth look at CacheCade, a new approach to storage systems that allows the perfect fusion of HDD capacity and SSD speed. With many large databases and enterprise users ‘caught in the middle’ with large HDD arrays, yet needing more performance from their existing infrastructure, CacheCade is a great option that allows the best …

One can improve the performance of small files by up to 50X which for certain types of setups can reap HUGE results. Webservers, File Servers, and OLTP (Online Transaction Processing) will benefit tremendously. There is definitely a large group of users that would be very interested in combining the positive aspects of both solutions (HDD/SSD) into one cohesive unit.  How …

After a period of time the SSD cache is going to be accessed quite frequently, and this has other advantages. Right now Cachecade is a read-only layer, so it might not be easy to understand the tremendous benefits that it has in regards to write performance on the HDD array. By freeing up the HDD from the most constantly addressed …

CacheCade performance is much more dependent on SSD read performance than on SSD write performance, so the performance depends upon the size of the SSDs and the total size of the data hot spots. If there simply aren’t many hot spots on the array being accelerated, you will not gain as large of a performance gain. Once again, in our …

This is the Test Bench and a quick click will display it close up.  As you may have guessed, it truly is no ordinary Test Bench, and I have dedicated many many hours creating this build, which has been used in many benchmarking excursions and extreme overclocking sessions. She has even set a few HWBot world records along the way! …

This is the single source test. The straight read testing just uses a single test file of 50GB that is read from the array as a 4k (aligned) Random Read pattern, at a Queue Depth of 32.  With this test it is showing the absolute best case scenario, results are usually going to be 2x of the more demanding zoned …
