We have a 2 x cPanel HyperV VMs on RAID 10 Sata Enterprise Hardware with 6 x 2TB disks on one server.
Would changing it to the following be better?
4 x 2 TB SATA Enterprise Disks for the /home folders of cPanel (RAID 10)
2 x 250GB SSD Disks for cPanel OS and MySQL disks for those 2 HyperV servers, 1 SSD for each Server.
Another reason is we getting these speeds from HyperV from inside the VM:
dd if=/dev/zero of=/root/testfile bs=512 count=1000 oflag=dsync
1000+0 records in
1000+0 records out
512000 bytes (512 kB) copied, 0.352809 s, 1.5 MB/s
dd if=/dev/zero of=/root/testfile bs=1G count=1 oflag=dsync
1+0 records in
1+0 records out
1073741824 bytes (1.1 GB) copied, 30.3307 s, 35.4 MB/s
Should be getting higher speeds fro 6 x 7200rpm disks in RAID 10 on hardware raid with BBU writeback I'm sure.
Thoughts?
