Managing in the Data Center - 12 Scenario 2 – Running out of File System Space Solutions  Offload non-critical data – Delete non-essential data – Move older/seldom used data to other media  ILM/HSM strategy  Easy retrieval if needed  Extend File System – Operating System and Logical Volume Manager dependent – Management tasks seen in Scenario 1 will apply here as well File System Warning: FS is 66% Full Critical: FS is 80% Full

13. © 2006 EMC Corporation. All rights reserved. Managing in the Data Center - 13 No Yes No Scenario 2 – Running out of File System Space, continued Correlate File System with Volume Group or Disk Group. Is there free space available in the VG? Execute Command to extend File System. Is the File System being replicated? Yes Does the Array have configured LUNs that can be allocated? Allocate LUNs to server Execute Command to extend VG. Yes Does the array have unconfigured capacity? Configure new LUNs Identify/Procure another array No Does the server have additional devices available? No Yes No Done Yes Perform tasks to ensure that the larger File System and Volume Group are replicated correctly

15. © 2006 EMC Corporation. All rights reserved. Managing in the Data Center - 15 Scenario 3 – Chargeback Report - Tasks – Correlate Application  File Systems  Logical Volumes  Volume Groups  Host Physical Devices  Array Devices (Production) – Determine Array Devices used for Local Replication – Determine Array Devices used for Remote Replication – Determine storage allocated to application based on the size of the array devices Example: Array 1 Source Vol 1 Local Replica Vol 1 Source Vol 2 Local Replica Vol 2 LV VG FS Remote Array Remote Replica Vol 1 Remote Replica Vol 2 DB App

16. © 2006 EMC Corporation. All rights reserved. Managing in the Data Center - 16 Scenario 3 – Chargeback Report – Tasks, continued – Determine RAID type for Production/Local Replica/Remote Replica devices – Determine the total raw space allocated to application for production/local replication/remote replication – Compute the chargeback amount based of price/raw GB of storage – Repeat steps for each application and create report – Repeat the steps each time the report is to be created (weekly/monthly) Example: 2 Source Vols = 2*10GB RAID 1 = 2* 20GB raw = 40GB 2 Local Replica Vols = 2*10GB = 2*10GB raw = 20GB 2 Remote Replica Vols = 2*10 GB RAID 5 = 2*12.5 GB raw = 25GB Total raw storage = 40+20+25 = 85GB Chargeback cost = 85*0.25/GB = 21.25
