Assume bandwidth is not a concern. I am wondering if this is supported.
Solved! Go to Solution.

Re: EVA8100 and HP-UX 11.23
usually the 8 ports are divided into the 2 redundant fabrics (2x4). If you reduce the number of paths, you are reducing the host performance and also the load balancing features and you can come into the performance or availability problems soon

Re: EVA8100 and HP-UX 11.23
Yes it is supported, but from the FP point of view the downgrade of eva8100 to the eva4100/6100 is a strange idea

Re: EVA8100 and HP-UX 11.23
It would not be ALL systems taht are limited to just 4 of the 8 ports, just hpux.
We are using HP's rebranded Veritas DMP on our DB systems. For LVM based systems, just pvlinks, no securepath-autopath.
I am trying to avoid burning up all my device files for bandwidth that I don't need. Just brainstorming.
I'll have to look up the device file limits rule again, but I remember I was concerned about it.

SolutionAs for redundancy/performance: since PVLinks provides no load-balancing but only basic failover even only two paths per lun per server would be enough, one path to sp-A and one to sp-B.
Using four or all eight ports is only a performance issue and is only worth it when you can use the added performance on the server side (load balancing software)
Supported as in "it works and is allowed by hp" is even a single-path configuration, but this would lack redundancy of course.
