MSA1500 + 2 X MSA30 SCSI
The old msa30 contains 10K 300GB disks.
I need to divide the storage between 3 hosts. These hosts are connected via FC.
The MSA1500 has two active/active controllers but has only one IO module which connects to the msa30. The new cabinet has a dual channel scsi IO module.
What should I do :
Divide the cabinets over two IO modules on MSA1500 (need to buy another IO module) or connect trough the dual channel msa30 ?
If I create the volumes should i divide the mirrors on both cabinets and the raid6 only on on cabinet. In case of powerfailure at least the raid6 stays consistent ?
Every advice is welcome.
Thanks in advance

Re: MSA1500 + 2 X MSA30 SCSI
1) you need 2 more MSA1500 I/O modules and connect one to each MSA30 port.
2) buy a single bus I/O module for the MSA30 and buy 1 MSA1500 I/O module and connect them together.
Option 1 would be better since you will then be utilizing 3 SCSI buses for I/O instead of 2. I would create your arrays across the SCSI Buses, then create you R1, R5 or R6 Logicals

Re: MSA1500 + 2 X MSA30 SCSI
So the more IO Modules the better ?
Is it wise to devide the disks between the 2 cabinets ? If a powerfailure occurs i will loose my RAID6 ? or better to place every RAID6 on each msa30 ?
Thanks in advance

Re: MSA1500 + 2 X MSA30 SCSI
So i resume :
Buy 2 IO modules for the msa1500.
Is it wise to buy a third io module and a dual io module for the existing msa30 ?
Then the performance is devided between 4 io-modules?
hanks in advance.
