We are in a transition of our SAN storage from one EMC box to another. Since this requires my relocating 18TB of TSM server storage, I thought I would take this opportunity to revisit FILE devclass vs DISK, which we are using now.
I have been reading through the Linux Server Admin Guide on the "pro's and con's" of both devclasses. Still not sure if it would be better to go with FILE. Here is some info on what this server does,. For the server that would be using this storage, the sole backups are Lotus Notes/Domino servers, so the backup data profile is not your usual data mix (largely Notes TDP). No dedupe and no plans to dedupe. No active storage and no need for it. 4-5TB daily with spikes to 15TB on weekends - 95%+ is TDP When creating/updating the FILE devclass, how do I calculate/guesstimate the values for MOUNTLIMIT and MAXIMUM CAPACITY as well as the MAXIMUM VOLUMES? Unfortunately, the storage they assigned to me on the VNX5700 is broken up into 8-pieces/luns, varying from 2.2TB to 2.4TB, each. Looking for some feedback on which way we should go and why one is preferable than the other. -- *Zoltan Forray* TSM Software & Hardware Administrator Virginia Commonwealth University UCC/Office of Technology Services [email protected] - 804-828-4807 Don't be a phishing victim - VCU and other reputable organizations will never use email to request that you reply with your password, social security number or confidential personal information.
