Needs Your Advise on 64-bit AGGR

Good Morning NetApp Gurus,

My FAS3160  DOT 8.0.1 upgraded was done last night.

Would you be kind enough to advice?

  1. The suggested RAID Group Size for the new 64-bit AGGR ?
  2. Volume data migration from 32-bit to 64-bit AGGR procedure ?
  3. LUN data move procedure from 32-bit to 64-bit AGGR non-disruptively ?

Thanks in advance & Good Sunday

Henry

Hi there,

1) default values like on 32bit apply, be aware tho that you can rise the max raidsize for S-ATA drives up to 20 now

2) qtree snapmirror, snapvault or ndmpcopy

3) same as 2), there is a downtime involed tho, there is NO way to do it nondisruptive

Regards

Thomas

Would you be kind enough to also advice the pros/cons on using qTree snapmirror or ndmpcopy ?


Good Sunday

Henry,

qtree snapmirror can be updated several times as every snapmirror transfer can. and you can deceide when to update & break it.

ndmpcopy only allowes to be updated for 3 times (level 0/1/2 copy) thus cannot be that easily updated several times and it blocks the console during transfer, not allowing you to control the data flow etc.

I prefer qtree snapmirror BUT you can only transfer qtree & non-qtree data into a qtree eg:

filer1:/vol/data/dataqtree1 -> filer2:/vol/data/dataqtree1 for qtree to qtree data

filer1:/vol/data/- -> filer2:/vol/data/dataqtree2 for non-qtree to qtree data

filer1:/vol/data/- -> filer2:/vol/data/- will NOT work
