Reason and Prerequisites
You want to find out whether your BWA sizing is correct.
Solution
The only relevant measure for sizing is the “Disk Size”.
You can find this measure (column “Disk Size [kB]“) in tab “Usage -> Access Statistics” of the TREXAdmintool.
To be within sizing limits, the following statement needs to be true:
“SUM (”Disk Size [kB]“)” is less or equal than “0.5 * < SUM of main memory of all blades>”
Notes:
Backup blades are not taken into account for sizingAny other measure (like “mem. size”) is not reliable for sizing because it may differ during different times of data loads and does not cover worst case scenarios.
