SSD RAID 10 IOPS Testing – H700 Perc RAID Card Testing R710 Recently we’ve been playing with H700 RAID cards with SSD’s. We have had some issues which will be outlined in future follow up posts with SSD’s & H700 Compatibilities. 6 x 256GB Crucial M4 Firmware 0309 all confirmed in a RAID 10 array. Testing tool : Fio 1.38 64bit Fio is quite easy to configure and setup in all major linux distribution. We are testing it on Debian which is quite easy to install J From CLI (command line interface) just run the following commands: This will update the Package Index. The APT package index is essentially a database of available packages from the repositories defined in the /etc/apt/sources.list file. To update the local package index with the latest changes made in repositories, root@server:/# Apt-get update This command will then install FIO from the remote repositories & any dependencies root@server:/# Apt-get install fio We then want to create the actual configuration file which will have all the variables for this test , because we are utilising SSD’s it’s a good idea to setup the configuration file with the following settings The easiest way to create the configuration file is like this: root@server:/# nano random.fio Then you want to paste the following in: [random] rw=randread size=1g directory=/iops iodepth=403 direct=1 blocksize=4k numjobs=16 nrfiles=1 group_reporting ioengine=sync loops=1 The second last step is to create a folder where all the working/testing will take place in , in our case we created /iops….
