flow of the hardware check

[Former Member]

Hi Team,

We are trying to test the throughput using the hardware check for the backup file systems.

We have tried three test cases for short , long and very long.

Each of them specifies a data file max size for 5, 16, 32g. Wanted to understand what exactly would it mean will it create a file and then try to test throughput to the backup file system. Also can i increase the number from 32 to a higher value. What all should i be modifying. Can i get some information as to how does the hardware tool function.

hwval_client.py

hwval_master.py

hwval calls the above two python scripts. Wanted to understand if we can customize and test with a higher data file size.

32G is a small number for us since we have about 200 G data file.

Which figure should we be concerned about for backup file system. overwrite or write ones?

Hello,

the only information available about the hwcct is the one attached to the central note:

1943937 - Hardware Configuration Check Tool - Central Note

In the attachment of this note it is also mentioned what the IO test is doing:

"create a file and enlarge it to a certain size, overwrite the entire file and finally read the file. All these operations are performed with blocks of different sizes:

-- Data volume: 4K, 16K, 64K, 1M, 16M, 64M

-- Log volume: 4K, 16K, 1M"

The python coding should not be edited, unless you dare to risk inconsistent results as even the file sizes might have dependencies (e.g. calculations of write I/O and read I/O in bytes per seconds or other KPIs)

BR, Bojan
