SAN for small buisness |
|
|
I work for a small company that is thinking about migrating to a SAN
solution for our storage problems.
Our situation is this:
1. We have ~10 HP servers, some of which use 15000 Ultra 320 SCSI
disks, others of which use ATA disks (DL140 servers).
2. These HP ProLiant servers must be able to boot from the SAN.
3. I definitely want to use all (or at least most) of the SCSI disks
from our servers. Problem is that some are different capacities. Most
are 72.8s, but some are 146.8s. I know that as a general rule putting
drives of different capacities onto the same RAID array will truncate
the space, and I want to avoid that.
4. I want to go iSCSI for the networking, as the fibre gets so
expensive when adding additional servers. I realize that iSCSI can be a
performance hit, but I doubt that the disk IO will be the limiting
factor in our company for some time to come (I plan to run some disk
activity tests, haven't made it that far yet).
Any suggestions would be appreciated. My current thoughts are below.
1. Using a SANRAD V 3000 combined with a HP500 RAID controller for the
disks, and emBOOT to provide booting capabilities.
2. Possibly something like the DS300 from IBM. The DS300 is appealing,
but the rep from IBM said the disks we have couldn't be used the way
I want to. Could the IBM controller possibly be used with a HP drive
bay for the disks? |

Instead of telling what you want to implement, why not tell what your goal
is? Why do you think you need a SAN? Why do your servers need to boot from
it? Tell us what you want to accomplish, not what you want to tie together..

Well... depending on what you have in those servers for controllers...
the smart-array based controllers should be able to move disks
interchangeably with the HP StorageWorks MSA arrays. The MSA is a
smart-array based SAN storage array. Your host-based disks in a
smart-array could move somewhat transparently to the MSA, keeping all
data, raidsets, etc. intact.
To do ISCSI, you'd implement the HP StorageWorks IP Storage Router
2122-2.
Disclaimer: I do work for HP in the storage consulting practice.

Rob is 100% correct, what are you're storage problems? Maybe a SAN is
not the answer...
There's a lot of talent and experience in this forum, tap into it.

I would drop the older drivers and go with a proven NAS/ISCSI/SAN
solution like NetApp. this way no matter what you want to do the
storage will be able to meet the need. Mixing up the drives will in
the end cause you to take a performance hit and you will have to think
about hot spare issues with multiple drive sizes. |

As much as I love NetApp for NAS I do not recommend them for SAN. The
OP gave nowhere near enough info for anyone to really help.
For instance, if most of the requirements are satisfied by SAN then go
with HDS/HP/EMC/IBM/whatever and just front-end some NAS.
If NAS is the primary solution then determine if you really need block
access. If no, problem solved. If yes then maybe iSCSI would fit the
bill. In which case NetApp is great.
Need more info though. Specifically the actual problem to be solved.
