comment How to calculator IP range and subnets?
I'm voting to close this question as off-topic because Serverfault is a site for professional sysadmins - in the same way as I'm sure the math.stackexchange would expect its users to be able to count to 10 I'd expect SF users to be able to fully understand IPv4 as a minimum requirement - these teach this stuff to 12 years olds these days!

comment Lustre alternative for 70-node scientific cluster
Not 100% in agreement with regards to the closure of this question as I think you're looking for a broader solution than just 'buy this'. Anyway NFS is perfectly acceptable if each node is writing into separate files, where it's not ideal at that scale if when every node is writing into the same file/s - i.e. lots of locking going on. So have a look at your system to see how this behaviour works out.

comment IPTABLES and NFTABLES
Wikipedia and google do (en.wikipedia.org/wiki/Nftables) - nft is for newer kernels and is partially in user-space. We expect question askers here to have done the most basic of research on their own - please bear that in mind when considering asking again.

comment Building large RAM Computing Server with a limited budget (Bioinformatics)
As we make very clear when you sign up to this site we are here for professional sysadmins - who inherently build supported and supportable systems that are designed to run for years without major issue. The idea of going wildly against manufacturer's supported configurations sends shivers down our spines. That said there are systems out there that can easily so what you need for the budget, look at supermicro systems for one, they're not so well respected but if you look for say a Xeon E3 based server you can still get a lot of cores and the memory you need for the budgets you're looking at.

comment Convert single disk raid0 to raid1 on an LSI megaraid controller
Whether you can do it automatically via the controller or now I think everyone on this site would recommend backing up the server, rebuilding the array and restoring anyway - it's the only way to be sure it'll function as you wish.

When you sign up to serverfault we put words in front of you, we expect you to read them, one part says this site is for professional systems not home ones.

comment VMWare and storage virtualization solution
I do understand, I just don't think you understand the current marketplace for Storage - either way you're looking for product recommendations, something we don't do on this site - as we make very clear in the text you've ignored when you sign up here - ask VMWare directly.
