HDD choice for virtual setup running 4 x VM's (SBS2011 x 1 & Win 2008 x 3) - SAS or NL-SAS?
Posted on 2012-03-26
Would appreciate some advice with regard to choosing adequate HDD's for my intended virtual setup. I have a couple of systems configured but am having some difficulties choosing between SAS and NL-SAS drives.
My intended setup is:
Running 3 virtual servers (1 x sbs2011 standard | 3 x Win 2008 R2 Standard), using Win 2008 R2 Enterprise as Hyper V host running on a single Dell R510 server. The SBS VM will handle our domain & email roles whilst the other VM's will run the organisation's CRM, FileMaker Pro and other low activity roles. By low activity only approx 5 users connect to the CRM and 20 to the File Maker Pro DB. The SBS VM will service approx 20user but can swell to 60 users.
I have the server more or less complete bar the HDD choice. Normally I always plump for SAS drives but this organisation is not vast and I'm keen not to over spec. Dell has offered up NL-SAS 10K drives as an alternative that whilst not on a par performanace wise with the SAS drives they do offer a significant saving.
Ive not had much experience with NL-SAS drives in 24/7 operation and have read lots of articles and posts both slating performanace and reliability over their SAS cousins but 99% of these appear to be in much larger and more demanding environments than possibly mine will be.
Be keen to know if anyone with a similar setup is using the NL-SAS option and what their experiences have been or opted for SAS and why?
Thanks in advance,
