1 CIFS Share across Multiple File Systems

Question

Hi,

I was wondering if anyone knew if it was possible to have one CIFS share that spanned multiple file systems within the Celerra.

I have a requirement for a single data share that will have 2 or 3TB of data contained inside. I remember reading somewhere that it was recommended to keep File Systems around the 500GB mark but I am stumped about what to do when I need something bigger than this. I think 500GB is a good value for manageability and for backup's etc.

Would be helpful to hear the Forum's thoughts.

Many Thanks,

Dave.

Dave,you can create file systems up to 16 terabytes. I keep my file systems around 2T so that i can back them up in reasonable time. Take a look at documentation about nested file system, that was you can have multiple component file systems presented trough one share. How do you currently run your Celerra backups ?

What is your NAS Model and what version of NAS code you are running - which determines the maximum size of a file system.

However, as dynamox suggested, if you are not running too old NAS code (prior to 5.4), you can safely create any file system upto 2 - 3 TB considering the backup/restore time required for larger file system.

Thanks,

Thanks, I will take a look at that.I have inherited this environment so still trying to figure out how it has been put together. The backup solution is Networker via NDMP. The library is connected through a Brocade switch.

lots of customers are using 2TB or 3 TB file systems

my opinion - Just take a look how long your current backup of the 500GB file system takes - and if you can live with the backup taking proportionally longer then go with the large file system
