NBU dimensioning puredisk DSU
Good morning all,
today i need to dimension a new MEDIA for a bunch of servers that are going to be added to the one.
I'm talking of 10 servers someone with SAP db, below detailed:
2.35T of raw space (maximum disk capacity summed for all the servers).
370G Sap db+Arch logs (actually running).
Around (foresight) 500G of new DB (Sharepoint installation for Documentum)
Sap db+arch logs runs everyday.
Disks backup 1Full+6inc.
Sharepoint will run too everyday (i don't know if it will use mssql process or another specific one that can use inc+full).
Retention 2Weeks for all the backups.
I'm thinking about initial 6T of /DSU (PUREDISK with dedup) in order to stay quite for some time, but i would like to have a real and precise measrument to calculate it prior to stay far from reality.
