In my case I went back to a write speed of 90Mo/s. Sudo /opt/dell/srvadmin/sbin/omconfig storage vdisk action=changepolicy controller=0 vdisk=0 diskcachepolicy=enabled Otherwise try this command to enable the cache (it's persistent across reboot) : If you already got : Disk Cache Policy : Enabled then sorry there's nothing I can do for you. Sudo /opt/dell/srvadmin/bin/omreport storage vdisk | grep 'Disk Cache Policy'
DELL PERC H200 UBUNTU INSTALL
Sudo apt-get install -y -force-yes srvadmin-storageservices Sudo apt-get install -y -force-yes srvadmin-base Sudo echo 'deb /' | sudo tee -a /etc/apt//.list Start a command line (Application → Accessories → Terminal) In my case : .Ĭhoose your language and click Try Ubuntu So here is a quick translation.ĭownload the latest Ubuntu CD for amd64. It should not harm your data (at least not mine), but do a backup before. I found in a french forum a way to enable the disk cache. As my main use of this server was ESXi and I didn't wand to invest in a Perc H700 (with BBU), I continued the search.
DELL PERC H200 UBUNTU UPDATE
I also tried to update the firmware or find some hidden option but without any luck. Dell officially explains that as the Përc H200 does not have a battery, it does not use any cache (so far understandable) and it disables disk cache (unbelievable). Yes you read well, I bought an additionnal raid card (Perc H200) to have a write speed that lame (any 10 year old IDE drive can do better).Īfter a lot of googling I found out I was not the only one (some guy said that it took 1,5 week to create an RAID 1 array of 1TB). I started to make some test and finally found out that I had very very very slow writes : 12Mo/s. The installation works perfectly to the point where it feeled that many of my virtual machines were spending a lot of time in iowait. I was all about saving money and keeping ESXi compatibility so I choose the Perc H200 as the raid card with 2 SATA drives. I just bought a small Dell server Poweredge 110 II.
