SAN versus Local storage
Posted on 2014-10-23
I am currently provisioning equipment and resources for a client of mine and I could use some advice.
Company: Software developers with 100 employees
Requirements: ESXi server(s), lots of RAM & Storage
Comments: Super fast disk access is not a requirement (i.e. 7200 RPM drives are sufficient).
HA, sharing of data storage, load balancing are not necessary; most important requirements are ability to backup, and having necessary resources available
Since the main purpose of the servers is to do testing, no serious controls are required (except like I was saying backups and some level of redundancy with hard drives)
To meet the needs, I will be purchasing the appropriate vmware licenses and server(s) as required.
Now the question is how to go about identifying the type of storage that would best serve the company
I have a reasonable understanding of the SAN, which basically leaves me with 2 options:
1. Purchase a SAN and communicate to SAN via ISCSi (fibre channel is too expensive for the size of the company); Due to the size of the company, I am looking at the HP P2000 SAN; Server(s) would be diskless
2. Purchase servers with appropriate local storage;
I am not certain which way to go would be best. I understand the benefits of both, but possibly, based on requirements local storage would be sufficient. I can definitely purchase enough local storage in each server to meet the requirements.
Does anyone have any suggestions / recommendations as how to proceed?
Thanks in advance.
