WHS 2011: OS Drive Mirror - OS or Controller?


Kazz
 Share

Recommended Posts

I'm new to WHS but not server tech. In all candor, it has been a few years, though.

 

I'm building my first WHS (2011) based on an MSI H67MA-35. I'm planning on mirroring two 3Gbps SATA WD 320GB drives for the OS (drive C:) and using a single 6Gbps SATA WD 2TB drive for storage.

 

I'm looking for folks' lists of advantages/drawbacks most specifically as they relate to managing a drive failure and replacement. Using the OS, it seems to me at first blush, would make it all dependent upon a GUI and very straightforward.

 

Anything else I should consider?

 

Thanks.

Ah. OK. Well, you won't be able to mirror those drives using Windows. Windows won't let you mirror the system drive - I tried it recently and Windows just doesn't give you the option in Disk Mangler.

 

That leaves you with just the onboard RAID option, unless you want to install a RAID card.

 

I have my own WHS2011 set up using the Intel ICH7R RAID1 feature of my mobo to mirror 2 Maxtor 250GB drives. It hasn't happened yet, but I presume I will get a warning from the system if one of the drives fails.

Really? Not an option? I thought folks on here were talking about using the OS. Perhaps my choice is made for me, eh? Thanks for your experience!

Most everyone has been using the IcyDock adapter for OS mirroring (see my sig line) with laptop drives. Works great and installs in seconds.

Interesting. Thanks. I have my 3.5" 320GB drives in-hand though so I'm going to waste space, apparently. *Laugh* No big deal. It's all going into a circa 1997 tower case with acres of 5.25 drive bays. I purchased 5.25-3.5 bay adapters for just this purpose.

 

I'll be keeping those in mind when I add drives to PCs in the future.

 

Thanks!

You could still RAID 1 those OS drives off the MOBO and use a controller card for the data drives. Nothing wrong with repurposing an old case. I wish I could find the right MOBO and PSU combo to update an almost 10 year old Dell 600SC case.

I'm going to RAID 1 the 2 OS drives. The question was whether there was an advantage to using the OS over the MB. But, if WHS 2011 is incapable of mirroring (how silly is that? No drive extender OR mirroring???) then the MB it will be.

 

Data will be on the single 2TB. I have visions of the upgrade after that being RAID 5 of some 3TB drives. But, we'll see what time and finances dictate.

 

Thanks!

I mirror system drives all the time inside windows and WHS. We talk about it several times on BYOB. You can mirror the OS drives using the OS and then just attach the 2TB data drive. Don't spend money on a RAID controller until you have more drives. I would highly recommend getting a second 2TB drive and mirror tha as well until you upgrade to the storage.

      Hi everyone, today I wanted to install esxi 6.7 to try out the various functions, my question is the following, I have a server where I have installed esxi in an SSD and I have two other 4 tb disks so 8 tb total.  I would like to make sure that when I create a virtual machine in this case I will install the various virtual machines in the SSD and use the two disks for data.  So how can I do this?  Thank you very much for those who can help me.

      Looking for a quick answer here from someone in the know...
       
      I upgraded some of the internals of my Gen8 server and at the same time I did a BIOS reset as I had forgotten the password that I had set years ago. When booting back up the upgraded hardware was detected and fine but I received Error 1784 - Drive Array - Logical Drive Failure. I believe this is due to a setting change in the BIOS and not anything hardware related. I have gone into IP/SSA and see the array needs to be rebuilt. I had all drives configured as single RAID0. It says all data will be lost if I reconfigure this but I remember reading somewhere on here that the data will be fine if I reconfigure as RAID0.
       
      I do have a backup of course, but it’s not a high availability mirror and will take some time to get back the way I had it, so just want to know if it’s safe to reconfigure the RAID0 without erasing the drives. I have tried pulling the drives out and connecting them to another PC and they are fine. Can anyone tell me which options to choose to get these back to normal and remove the flashing red light?
       
      Thanks 😶

      Greetings,
       
      I'm new to the HPMSG8 world and so far I'm loving it. I have a stock Xeon with 16G of aftermarket memory with iLO patched to 2.70. Next up is adding a RAID card, so I can put my boot SSD on the onboard RAID. I picked up a LSI SAS9211-8i on Amazon, but am struggling to flash it to IT mode on the MicroServer. Is this even possible? Unfortunately, the only other system I have with PCI slots is 32-bit.
       
      Any pointers would be greatly appreciated.
