Baby SAN (Storage Area Network)

This is my new baby SAN (Storage Area Network), it’s a MSA 1000 (Modular Storage Array) with Active/Active Dual Controllers, Dual SanSwitch 2/8 connected to a MSA30 external storage box. Currently filled with 18.2 and 36.4GB disks to test and configure before moving any data.

This will replace my aging ’s which are , connected to host VMware servers at 1 Gbit/s to provide shared storage. using Compaq/HP Smart Array 5300 with modules. Although the MSA1000 is now discontinued, it’s a real SAN, and can be connected to HBAs at 2Gbit/s, so potentially faster than iSCSI or NFS even with jumbo frames over gigabit networking, until I get some 10Gbit/s LAN switches! No longer supported by HP or VMware for vSphere 4.0, but then again neither are my RA4100’s!

The manual states, “Migration from RA4100 to MSA1000, removed all the discs from the RA4100, re-insert in MSA1000 in correct order, it will recognise the array configuration, and mount the volume, it should then be ready to present this LUN to your servers” – sounds too easy to me!

it uses a slightly unusual variation of an RJ45 connection, which further research indicates is called an RJ45Z. A normal RJ45 cable doesn’t work, because the Rj45Z has a special notch on it!
