Maximum FA Port utilization Limit on VMAX 20K.
Hi All,
What is the Maximum IOPS in Vmax 20k for FA ports .
Example we have FA -3E ports with utilization as below:
05:32:04 DIRECTOR PORT IO/sec Kbytes/sec
05:33:05 FA-3E 0 359 7390
05:33:05 FA-3E 1 976 21526
05:34:06 FA-3E 0 237 3906
05:34:06 FA-3E 1 907 16248
Any way to find which type of IOPS its read hit/miss or WP etc.
Thanks and regards,
Santosh S

Looking at the output above, you're running a command like:
$ symstat -i 60 -type PORT -sid 1234 -dir 7E
12:37:19 DIRECTOR PORT IO/sec Kbytes/sec
12:38:19 FA-7E 0 51 106
12:38:19 FA-7E 1 212 1970
12:39:19 FA-7E 0 11 16
12:39:19 FA-7E 1 61 586
12:40:19 FA-7E 0 48 94
12:40:19 FA-7E 1 44 560
12:41:19 FA-7E 0 34 56
12:41:19 FA-7E 1 10 92
Which is reporting I/O against the VMAX front-end ports. To see read/writes, change the command from "PORT" to "REQUEST":
$ symstat -i 60 -type REQUEST -sid 1234 -dir 7E
DIRECTOR IO/sec Cache Requests/sec % RW
12:40:26 READ WRITE RW Hits
12:41:26 FA-7E 76 1 54 56 98
12:42:26 FA-7E 102 1 82 84 100
12:44:16 FA-7E 107 3 72 75 99
12:45:16 FA-7E 163 8 129 137 96
12:46:16 FA-7E 125 8 97 105 95
