[nvelis] “I’ve just ordered a 2TB Lacie SATA 4 Disk Array and after reading this I’m thinking about canceling it. I don’t know anything about the SATA to Fibre option. Are there any brands/models you can point me to? I’m not sure if the seagate model you referenced is Sata to Fibre but I would like to investigate this before my drive ships.”
Well, I wouldn’t cancel your order just because there are RAIDs/JBODs with Fibre Channel interfaces and SATA drives in them. Fibre is nice because you can use optical cabling and put the array in another room, but you definiterly pay a price premium for Fibre connectivity, both for the host adapter card and for the interface on the array. Basically, if you get into Fibre interfaces, you’re in a whole new price bracket.
I got pricing quotes for the Rorke Data Qubex, which is a desktop (not rack-mounted) array with 6 SATA drives, a 4Gb Fibre Channel interface and a hardware RAID controller. The pricing is:
1.5TB for $5045.00
2.4TB for $6999.00
3TB for $7699.00
I think the Huge Systems arrays are a bit better in terms of pricing if you’re interested in RAIDs with a Fibre Channel interface. Huge’s MediaVault 4105 1.25TB array has 5 ATA drives and a hardware RAID controller that can be configured as RAID 0 or RAID 3. It has a single channel 4Gb Fibre Channel interface. B&H lists it for $4183.00.
Medea sells a 1TB 5-drive RAID 3 array with a single channel 2Gb Fibre Channel interface for $3698.50 at B&H.
For the convenience of Fibre Channel, you’re probably going to pay an extra $1K to $2K over a similarly-sized array with a SATA interface.
Several manufacturers are now offering SATA JBOD arrays with Infiniband ports, which carry 4 SATA channels over a single connector. They usually bundle a SATA to Infiniband PCI card with the array. While the maximum cable length isn’t nearly as long as what you can get with fiber optic cables using Fibre Channel, the single Infiniband cable is an improvement over using multiple SATA cables.
