RAID 5 / RAID 10 question
Posted on 2013-01-21
I am looking to purchase a few ESXi servers. I'm wondering what raid level would be better.
RAID 5 or RAID 10.
I'm thinking if I do RAID 5, have like 7 disks in the array and one hot spare. With RAID 10, I'm a little confused with how many drives can fail and if it requires a hot spare.
Overall, I'm thinking maybe 3 host systems. Maybe 10 guest servers total. However, I'm concerned with virtualizing Exchange and SQL and a file server. How performance may be in doing this. Currently they are on there own physical hardware. Though probably one on each of those host systems.
The company isn't super intense. We have about 65-75 users total. One major SQL database everyone accesses.
I'm just not to confident in server sizing... Haven't had much experience picking the hardware. Looking to know if I'm on the right track and such.
