comment Switching to HP microserver
Performance is very hard to predict, especially since we aren't talking about only changing one parameter and the load isn't constant and predictable. The only real answer is testing/benchmarking your particular usecase

comment Installing packages with dependencies using puppet
It's not necessary to add the dependent packages even without these options. It should be pointed out and emphasized that installing unauthenticated packages poses a security risk. A better idea is to fix the problem by installing the keys used to sign the packages.

comment “Mandatory” free space on a SAN?
Any properly engineered system, if it needed reserve space in order to function properly, would reserve space without offering it for use by clients. Snapshots may need space and Copy-on-Write filesystems do, but those usually have a small reserve for those purposes. At least by default, which can of course be overridden by the users if they are willing to take the risk.

comment When reading SSD drive specs, what's the difference between MB/s and IOPS?
You are clearly talking about ZFS-on-Linux. Oracle sells Solaris with enterprise supported ZFS and OmniTI sells commercial support for Illumos (i.e. OpenSolaris) based OmniOS with ZFS.

comment When reading SSD drive specs, what's the difference between MB/s and IOPS?
These days hardware RAID controllers can form the bottleneck of setups with lots of SSDs. Each SSD can handle lots of IOPS, but the RAID controller may be unable to handle the combined IOPS of all SSDs. Software RAID (or ZFS) can be a better solution.

comment What is the difference between iptables -X and iptables -F?
The difference is the same as deleting all files in a directory, or the directory itself.
