VRTX Storage Partition

Question

Hello,

I have a VRTX with two blades. I have 3 disks (1.82Tb each). With those disks, can I create a LUN with RAID 5 and then partition them? In other words, can I create a virtual disk in RAID 5 with those disks then subdivide this virtual disk into two partitions? If it's possible how can I achieve this?

I saw if we have a virtual disk, we have also a maximum size (let's say 2Tb for example). If I create a virtual disk but instead of taking all the 2Tb I only take 1Tb. Where are they gone the others 1Tb? Are they definitively lost?

Thanks and have a nice day.

Hi,

This document helps explain how it works. https://downloads.dell.com/solutions/general-solution-resources/White%20Papers/Dell%20PowerEdge%20VRTX%20and%20VMware%20ESXi.pdf

What OS are you running? You can share the same RAID 5 with both blades. You can use all the space on split RAID 5s, you don’t lose the space.

Hi Josh,

Thanks for your reply. I'm running windows server 2012 R2. Can I select 3 disks for creating a RAID 5 virtual disk and then, in this virtual disk split the space in 2To and 1To if the total space of the virtual disk is 3To?

Thanks for the document. I saw that it's only possible in VRTX (if I take my above example) to allocate all the 3To and then split the space on OS like we want. is that an only possibility?

Thanks for your reply. Just for test purpose, can I have the procedure of slicing a virtual disk?

That is the best way to do it on all of our servers. Slicing the virtual disk can cause issues during rebuilds.

When I create virtual disk using disk 1, 2 and 3 for example, even if I didn't use all of space, if I want to create a new virtual disks, I can't select disk 1, 2 or 3 (they all disappear in the menu f creating virtual disk).

Thanks for your support.

Create a virtual disk and don’t use all of the space then create a second one with the same drives.
