I've got my hands on a HP N40L.
Can i use raid 1+0 on my 4 2TB WD RED or only 1 and 0.
Thanks for the help.
Hello! I put P222 on my Gen8 server, but I can not use RAID6. Can someone share the key?
I have recently found the time and energy to set up my Microserver.
Could someone please confirm if there are any issues with Creating a Raid 1 array with BAY 1 (6Gb/s) BAY 3 (3Gb/s). My logic is that speed of data access takes precedence over mirroring speed so 1 logical drive of Bay 1 & Bay 3 (Raid 1) and the other logical drive of Bay 2 & Bay 4 (Raid 1).
Is this a good Idea or I have I overlooked a potential technical issue. I searched the web for a possible answer but nothing came up.
Hi guys, this will be quite long, so be warned :-D
I run Microserver Gen8 for several years now. I have one issue which happens on any cold boot (swich off the server, then switch on; no need to remove power outlet).
My config is following:
* Linux Debian operating system
* SSD in optical drive bay connected to SATA intended for ODD, intended as main system disk holding Debian Linux
* 3.5" HDD in bay 1 used as single drive
* 3x 3.5" HDDs in bays 2-4 used in software RAID 5 (mdraid, no LVM)
To be able to boot from ODD SATA connector holding SSD with Linux, I needed to configure booting from integrated RAID controller and configure my SSD as one-disk-only RAID0 array. This works perfectly - I configure this logical volume in storage administrator and set it as bootable and server boots perfectly. I can see the SSD as /dev/sde and I can access it directly, it is seen by the system as regular SATA connected HDD.
Upon coldboot, HP RAID configuration is lost. If I boot from Debian Rescue disk (I have one permanently in iLO SD card slot), I can still see my SSD as /dev/sde and I can access all the data with no issues. When I open HP Storage Administrator and go through creating new array consisting of the SSD only, data is not lost and after setting it as bootable I can boot again without problems.
So what now?
I have a backup plan that would consist of using SD card in iLO slot as boot drive that would hold just GRUB and will be able to hand off all stuff to my SSD.
However, I would like to find out what is wrong with the HP RAID controller. Is it me who is stupid or just the controller does not support this unusual config?
i have .. i don't know its a big problem or a small bug but i do not see a single HDD in my Raid Controller..
But as soon as I attach a SSD to my ODD port, it will be displayed. Can anyone explain to me?
I hope someone can help me
