Hi,
I'd be interested to hear from anyone running a similar configuration
I'm running a somewhat similar configuration here. I'm wondering why you
have left out SSDs for the journals?
I gather they would be quite important to achieve a level of performance
for hosting 100 virtual machines - unless that is not important for you?
Have you considered having more than 3 servers?
If you want to run with a replication count of 3, I imagine that a
failed server would be problematic. But perhaps it is not important for
you if you have to live with paused VMs for a while if a server dies?
Do you know what kind of disk access patterns those 100 virtual machines
will have? (i.e. is it a cluster computing setup with minimal disk
access or are they running all sorts of general purpose systems?)
Purchases have to be made via Dell and 10Gb ethernet is out of the
question at the moment.
Why do you consider 10 Gb ethernet to be out of the question?
I looked briefly at Dells site and the added cost of getting a dual-port
10 Gb NIC instead of a quad-port gigabit is just 368$.
You could opt to buy their 2 TB SATA drives and 10 Gb NIC instead of the
2 TB SAS drives - and the cost would be the same.
A 10 Gb switch with enough ports for this setup can be had for 920$. As
you would need double the amount of ports in a 1 Gb setup, the
difference in cost for the switch would be quite small. Especially
considering that you would get 5 times the bandwidth adding only a few
percent to the total costs.
