iSCSI vs SAS (SMB3 vs Block Storage)
Posted on 2014-02-28
We are coming up to the hardware selection for our ERP (Dynamics AX 2012 R2) implementation and we have almost chosen what we need. The shopping list is below:
P2000 (12 disks, one RAID 10 Array) [10gigbit iSCSI dual port controller -OR- 6Gigbit SAS]
2 * HP G8 (2650-v2, 64GB Ram, 2gb RAID controllers, etc.) [10Gigbit iSCSI -OR- 6Gigbit SAS]
The above servers will be in running Windows Server 2012 R2 in a two node cluster configuration with the usual back-end storage setup [iSCSI or SAS].
However, we wanted to know what would be a more appropriate setup for us.
1. 10gigbit iSCSI configuration with the complexities of IP management and Block Storage
2. 6gigbit SAS setup with standard attached storage with replication or a simple cluster
In both cases 6gig or 10gig is more then enough for the back-end bandwidth but we were mainly thinking which would be easier to run long term and more appropriate. There is no real future expansion needs and two nodes would be the maximum the setup will ever be. We are trying to keep things simple yet redundant. Does SAS require clustering?
