Let me know if i need to change or configure anything else to make the
I/O a bit faster than what it currently does. I cannot go in for using
SSD's due to budget constraints. Need to make the best use of the SATA
disks that i have currently.
so, you have 2x2 ST91000640NS
http://www.seagate.com/products/enterprise-servers-storage/nearline-storage/enterprise-capacity-2-5-hdd/
those are "Nearline" disks, 7200RPM. They are intended for bulk
secondary storage, archives, backups and such.
you said you have a number of virtual machines all attempting to access
this raid10 at once? I'm not surprised that it is slow. You're probably
limited by random IO/second, that raid likely does around 250 random
operations/second. share that between 6-7 virtual systems and if they
are all doing disk IO, they are going to slow down each other.
