I'm familiar with that chassis so I'll take a stab at this one. (I own the RPC-4220) I am just only presenting the hard drives to the operating system (ESXi) vanilla, meaning as 4 TB drives for 24 QTY. When using this method, a RAID controller is not required for implementation. A HBA (Host Bus Adapter) will suffice and they are significantly cheaper. ...
As per this document on ESXi 6.0 Configuration Maximums, a single VMFS5 partition has a maximum size of 64TB. There is no limit to the number of devices on the underlying storage as VMware will not be accessing individual disks directly - this will be done by your RAID card. If you will be using RAID0 across all of your 96TB of storage (which is a very bad ...
You are not wasting space. tmpfs has to be used before it will use RAM and paging space. free -h will show you memory use in human readable units. If you were using tmpfs space, that would be under shared.
Recommended disk format size in Azure for any type of disk is 64K not 4K. This is due to the network nature of how storage is delivered to the VM. Try your tests with 64K.
There are some limits in Azure Premium Storage that you should consider to get optimal performance. In particular as you can see here there are IOPS and Throughput limits per premium disk. And they are different for different disk types. Moreover there are some limits per VM Size. So for the best result you should choose right VM Size, disk type and number ...
This does seem kind of round-about, do I have any better options? Your general idea is spot-on. I would personally suggest using ZFS with Solaris or FreeBSD, but mdadm might also work. Maybe though you don't get all the advantages I write about in this post, so take that as a disclaimer. This post will be quite long, I apologize in advance for the wall of ...
