Deploy Dell PowerFlex v3.6.x

Prepare server operating systems for support of large-scale systems (up to 2048 SDCs)

For large-scale systems with up to 2048 SDCs, prepare the operating systems of servers that will host MDM, SDS, SDR, and PowerFlex Gateway components.

1. On servers hosting MDM, SDS, SDR, or PowerFlex Gateway components, do the following:
   1. Run this command:

      cat /proc/sys/fs/file-max

      The output for the command is the number of files that can be opened by the operating system.
   2. If the number is 24576 or higher, go to step 2. If the number is less than 24576, go to the next sub-step.
   3. Open the file /etc/sysctl.conf using vi.
   4. If the following line exists, edit it with vi. If it does not exist, add the full line with the following setting:

      fs.file-max = 24576

2. On servers hosting MDM, SDS, or SDR components, if the following lines exist in the file /etc/sysctl.conf, edit them with vi. If they do not exist, add the full lines with the following settings:

   net.ipv4.neigh.default.gc_thresh1 = 8192
   net.ipv4.neigh.default.gc_thresh2 = 16384
   net.ipv4.neigh.default.gc_thresh3 = 32768

3. Save the file.
4. Apply the changes using the command:

   sysctl -p

5. Repeat this procedure on the next server, until all servers are configured.
