Better SSD throughput on R710

H700 is a 6Gbps controller, the PERC 6 is 3Gbps, so there will be "some" increase there, but there is also a chance that the SSD's won't know how to successfully negotiate the full 6Gbps speeds with the controller.

Migration of PERC 6 VD's to an H700 is supported.

I'm curious how performance gain I would see. If I do just a default run of CrystalDiskMark 5.2.1, I see a max read of 303.6 MB/s    3 Gbps should theoretically be 375 MB/s    

I'm not sure if I would get closer to 500-600 MB/s with a controller upgrade, or not. It's a bit of a pricey experiment for me. I can't find an H700 for less than $200 with shipping, etc.

I missed your most recent response before typing this one. Just consider this me thinking out loud :)

Thanks for the response. I wonder if anyone here has some disk performance numbers for SSD on H700. That would be a very helpful comparison. 

When you say migration is supported, is that simply booting up and following the on screen menus? Or is there a more complicated process?

Thank you!

I don't know of any, but there probably are someplace. Non-certified drives may experience any number of issues. The most common ones are not negotiating the correct speeds and not showing the proper status lights on the tray.

You power down, replace the 6 with the H700, when you power up, it may import the configuration automatically, but if not go to the CTRL-R utility for the PERC, F2, Foreign, Import if it did not import it.

The PERC H700 is on the ESXi compatibility list.  Make sure you update all the firmware on the PERC controller card, and the BIOS. at LEAST 6.4.0    6.5.0 is out and it addresses the Heartbleed/spectre issue.  I have successful test going from PCIe SSD to RAID10 with 15K RPM SAS spindle drive at 700+ MB/s Write speed to the spindle array, which far exceeds the 1GB NIC (120MB/s throughput on the LAN).  Use the Samsung 850 pro or 860 Pro SSD's for OS, you can pickup a CDROM SSD caddy 12.7mm for the OS, it will run at 3.0GB but it's good enough for OS, EVO's won't work they won't know how to handle the RAID. the latest version of the PERC h700 Firmware https://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverid=2948g BIOS 6.5.0 https://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverid=1y3xn I use a Windows installation to update the bios firmware and lifecycle controller. It make is alot easier.  I get phenomeonal performance out of these R710 servers. I've also had great success with Hyper-V 2016 and have since switch myself and my clients from ESXi to Hyper-V. Because with Hyper-v we can use vmotion for free, though hyper-v calls it replication.
