Hard drive recommendations
There are hard drive recommendations to follow if you install Apex software on non-VIAVI hardware.
If you want to use the software version of Apex on your own hardware or to put Apex in a virtual machine, the table below lists the minimum requirements with these changes (as appropriate):
DATA array: Four (4) disk RAID5. The more read speed you have, the better off you will be.
Hard drives: 7200 RPM platter HDDs. 5400 RPM HDDs and solid state drives (SSDs) are not recommended.
