Which four are key attributes to set up a ZFS Storage Appliance for Microsoft Exchange?
A. serial number of ZFS storage appliance
B. read/write SSD configured
C. RAID1
D. block size 4k
E. iSCSI protocol
Correct Answer: ABCE
Explanation/Reference:
B: The transactional log and database elements of ZFS send synchronous writes that require acknowledgment from persistent media. For this reason, Write Flash Acceleration SSDs greatly improve the write performance of the ZFS Storage appliance.
E: The implementation of Exchange 2010 and 2007 on the Sun ZFS Storage 7420 can use both iSCSI and Fibre Channel target modes.
Incorrect Answers:
D: The main item to note is the volume block size set to 32k. This 32k volume block size has been found to yield the highest performance on the Sun ZFS Storage Appliance with Exchange 2010 databases.
