SSD Option for SNS-3695

Damien Miller — Fri, 02 Aug 2019 16:13:14 GMT

The SNS-3695 is built with 8x 600 GB 10k hard drives, and for a PSN I feel that is fine. Has there been any thought put in to offering an option to replace these drives with SSD's? The primary use case I have in mind is for the monitoring nodes.

Since it is not possible right now when ordering, is there a possibility of field replacing the HDDs with SSDs, understanding that there would be RMA implications?

- I wouldn't recommend this on an appliance : 1) Even if some has slightly modified the standard disk driver from the underlying OS, you will probably get into trouble. 2) More important ; the product is no longer certified on modified hardware configurations.

That's why I'm raising the question if it has been considered, support can be added if it becomes a tested configuration or orderable.
Cisco's own super MnT testing numbers on a 2.4 3595 w/ 256 GB of memory demonstrated that the real performance gains are had with SSD storage, and not the just the memory increase.

It's extremely hard to get customers to buy in to 256 GB VM's with 24,000 MHz reservations.

You should be discussing this with ISE-PM team or in the security partner community where the PMs sometimes roam 🙂 since it is a feature request. Us TMEs don't get involved with that too much
