mmm...delicious cheese, oh and I design and build large video-on-demand systems, but let's get back to the cheese...

Fair enough, I don't use it so was assuming it did what happens to physicals, good spot, I'll delete shortly.

comment RAID0 : best chunk size for fileserver with average 650KB files
With four disks in R0 I'd be tempted to go with a 256KB chunk as that means you should be able to store one whole file in one chunk per disk which should help with the random-read. What would help more would be to use faster disks in R10 but I'm assuming budget is an issue here. What are you going to do when you lose the array by the way, I'd imagine this will happen around once a year.

comment Network access sometimes lost, disabling port security temporary solves?
Anyone running a client-based hypervisor such as VMWare Fusion/Workstation or that bloody-awful virtualised-XP in Vista? They can generate a second MAC down the link you see.

comment Persistent Disk Name in RedHAt Cluster on VMWare Workstation-10.01
I don't think you're helping yourself here by using VMWare Workstation - you can do this sort of thing but really you should be using ESXi for this instead, I think it'd go much smoother.

How many disks are you looking at using in this R0 and what will be doing the 'raiding', a hardware controller or software?

How big is the total volume size needed for this, the reason I ask is that for very small files such as this I've had some really good results with PCIe-based flash (FusionIO in my case) than with R0 - but obviously it's more expensive hence my volume question. Have you no 1MB option?

comment How many volumes on NAS?
@spirited - just to reiterate what SvW said - it's almost negligent of NAS manufacturers to be selling RAID5 devices these days - we can bore you with the details but it boils down to today's large slow disks such as yours essentially guaranteeing write errors when fully written to - so in the event of any disk failing you'll replace that disk and it WILL have data on it that can't ever be read again - RAID6 or 10 don't have this problem - use those. Oh and one big volume and don't store backup data anywhere near primary data ok.

Good, they'll work just fine in either - but I really would advise dual PSUs.

comment MSSQL High Availability Advice Required
In that case just setup the cluster as normal and expose the server's IPs and the cluster object IP and point clients to them.

comment MSSQL High Availability Advice Required
You don't mention which SQL product you wish to use, if this was an MSSQL solution you could simply expose the Cluster VIP and allow it to load-balance itself - if it's another product the answer will vary with that choice.
