Storage Pools possible for AX4-5F8?

Hi All,

I have a CLARiiON AX4-5F8 that is attached to a Celerra NX4

I am looking to see if I can somehow create a storage pool with this setup? I am very new to EMC and don't know much about it.

Basically what I have now is two disk pools, 1 with 16 drives and 1 with 8 in a RAID10. I need these disk pools to come together in a storage pool so that I can increase spindle count and IOPS in a Citrix writecache LUN.

Is this possible with this model?

Hi,

Use of Storage Pool is available from FLARE 28.5, which is available for CX4 Models

There is no storage pool or virtual provisioning available for CLARiiON AX4 Models.

You may refer....http://www.emc.com/collateral/hardware/white-papers/h5512-emc-clariion-virtual-provisioning-wp.pdf for more details

Thanks

Madhu

On the AX4, what you can do is create LUNS or Virtual disks ( based on your requirements) on the two disk pools you already have and then assign them to the server whcih in this case will be the Celerra NX4.

And then from the celerra NX4, for each data mover run the folowing command so that each data mover can see the newly created virtual disks :

#server_devconfig server_x -create -scsi -disks

where x =2,3 etc depending on data mover slot number.

After that run nas_disk -l command to se the list of availbale disks :

#nas_disk -l

id inuse sizeMB	storageID-devID type name	servers
1	y	11263 SL7E9083600100-0000 CLATA root_disk	1,2
2	y	11263 SL7E9083600100-0001 CLATA root_ldisk	1,2
3	y	2047 SL7E9083600100-0002 CLATA d3	1,2
4	y	2047 SL7E9083600100-0003 CLATA d4	1,2
5	y	2047 SL7E9083600100-0004 CLATA d5	1,2
6	y	32767 SL7E9083600100-0005 CLATA d6	1,2
7	y	1811980 SL7E9083600100-0010 CLATA d7	1,2
8	y	1811980 SL7E9083600100-0012 CLATA d8	1,2
9	y	5631999 SL7E9083600100-000B CLATA d9	1,2
10	y	5631999 SL7E9083600100-000A CLATA d10	1,2
11	y	5631999 SL7E9083600100-0009 CLATA d11	1,2
12	y	5631999 SL7E9083600100-0008 CLATA d12	1,2
13	n	5631999 SL7E9083600100-0007 CLATA d13	1,2
14	n	5631999 SL7E9083600100-0006 CLATA d14	1,2

You should see thenewly created virtual disks ( in the above e.g. d13 and d14) that are not neing used.

Used those disiks to create a storage pool on the celerra Nx4. The Celerra automated volume manager will automaticall stripe the pool acroos all the volumes you specify which in the backened will be across both the disk groups.

see the nas_pool command for more details .

but I would use some this like this ( using d14, and d14 as an e.g)

#nas_pool -create -name -desc -volumes d13,d14 -default_slice_flag y

To make it simple you can't have this feature in an AX4-5.

The reason being you need to have FLARE 28.5 or later to avail this cool feature.

Thanks and regards,
