Hi All,
We are following the dell reference architecture for 5000 mailboxes Exchange 2016 environment. The document is also attached for reference with this post. Servers are R730XD with 16 x 8TB 7200RPM and 2 x 1.2TB SAS 10K drives.
Server have 14 x 8 TB drives for Exchange DB and Logs and 2 Spare drives ( 16 drives in total). In storage architecture it says (Fourteen independent Raid 0 disks can be used to store copies of Exchange databases. A Raid Controller Can be used to create independent Raid 0 volumes by using internal drives." It says to create a 14 x 8TB RAID-0 for database and logs.
Q: Does this mean a single 14x8TB raid 0 group or they mean 14 Raid (Raid 0) group and each Raid 0 with single disk?
Q: If they mean to create one Raid0 group with 14 drives then it says to keep one drive for restore LUN? From where we will restore a LUN when, on a drive failure we will lose the entire raid 0 group?
Q: keep one hot spare - that’s understandable
Will be grateful if someone who has knowledge of these servers and storage layout shed some light and provide guidance
Thanks and regards
