comment Wipe is very slow. Too little entropy?
I don't understand why someone would use random/urandom on a modern disk anyway, SSD or not - zeroing would be quicker and just as effective.

Ok Thomas, I've not seen that method used before but essentially Ed's answer above, to update your controller firmware and use JBOD mode stands.

@thomashill - still confused, how do you see the failover clustering working? don't you need shared disk?

@thomashill - I'm confused - a P420i is for internal-only disks, are you looking to connect the internal disks of a server to a second server's HBA for failover clustering or have you got an external disk shelf that you've not mentioned?

comment Mounting Single San Drive on Multiple Hosts
More than happy to help, come back if you need further clarification. One option would be to use the SAN to present a single large LUN to a single server or VM that then uses that as a volume and then re-shares ut using a NAS protocol (NFS or CIFS/SMB) via Ethernet to your clients), it can be a bottleneck and SPOF but it works.

comment Converting IP addresses from Hex to normal format in Splunk
I'm sure you could do it via transforms.conf on the originating forwarder but to be honest it's probably easier to change the original output, what's generating this output?

comment Optimum LUN size for LVM created NFS share
I don't understand the question - can't you just have one 80TB PV, and 80TB VG and then 70TB and 10TB LVs? Why are you considering 'carving' it up like this?

comment Low TCP down speed on network interface
You need to swap the cables and IP's between this suspect port and any of the others to figure out if it is the port that's the problem or the downstream link.
