We have purchased Dell PowerEdge R730xd for Exchange services and are looking to best practices document for Exchange 2016 implementation by Dell.
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? For reference please check page 38 of Storage Architecture section in attached document.
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
