Hello Everyone, I have this weird situation. I have a PowerEdge R710 server with two PERC H800 cards, the PERC H800 cards are connected to a PowerVault MD1200. Here is how everything is setup
First PERC H800 Connector 0 is connected to one of the PowerVault MD1200 EMMs which cosists 6x4TB SAS drives
Second PERC H800 Connector 1 is connected to the other of the PowerVault MD1200 EMMs which also cosists 6x4TB SAS drives
I used the Open Manage server administrator to setup RAID 10 with intelligent mirroring on both the cards. When choosing the drives I chose all the drives. After the RAIDs were initialized I realized that virtual drives showed a total capacity of 24 TB on both cards. Further investigation revealed that the same drives were assigned to both the RAIDs. I have a total of 48 TB available to me on both RAID 10s, the total capacity of the drives is also 48 TB. Now I understand that RAID 10 halves the total capacity of the drives, then how is that I have the total capacity available to me (24 TB on each RAID 10) and how is it that both RAIDs are using the same drive? is that a benefit of the intelligent mirroring feature, or is it just a glitch. I will appreciate your help on this. Thanks!
