Обсуждение: Off-topic - Hardware recommendation
I apologize for the slightly off-topic question.
I will be building a new PostgreSQL server running 8.4 on FreeBSD 7.2 64-bit.
The nature of the application dictates that we use shared storage to provide high availability (in case one of the servers has a failure).
After doing some research in the various lists, it is apparent that an iSCSI SAN is NOT the way to fo, so we are looking at getting a Fibre Channel SAN (a Hitachi).
My question deals more than anything on the Fibre Channel host adapter – is anyone using a Finre Channel adapter on FreeBSD which they can recommend?
My biggest concern is to get one that is definitely supported.
TIA,
Benjamin
You are probably best off asking this on a FreeBSD list.

At the risk of starting a flame war, I'd suggest that you compare the cost and benefit of the proposed solution to replication onto multiple servers. In my experience, SAN solutions have had more down time, worse performance, and more lost data than directly attached storage. The only thing that matched with the sales pitch was the higher price. Don't sign off on any solution without doing your own testing. -Kevin

We have two HP DL 385 accessing a Fibre Channel Subsystem http://www.starline.de/infortrend-eonstor-s12f-G1433-R1432/index.htm which has redundant controllers, each with 2 ports. In the HP we plugged FC controllers from QLogic: # lspci: Fibre Channel: QLogic Corp. ISP2432-based 4Gb Fibre Channel to PCI Express HBA (rev 03) Each of these controllers has 2 ports, so we have redundant access from each server to each controller. On the servers, we run XenServer 5 HP edition (booting from USB) and just had to select "use multipath" and everything worked automatically. We tried removing a single connection, and it still works like a charm. The reason why we didn't buy a HP DSA storage is that the disks are way too expensive from HP, we now use Fujitsu 15k disks and they are very fast and save a lot of money. mfg zmi -- // Michael Monnerie, Ing.BSc ----- http://it-management.at // Tel: 0660 / 415 65 31 .network.your.ideas. // PGP Key: "curl -s http://zmi.at/zmi.asc | gpg --import" // Fingerprint: AC19 F9D5 36ED CD8A EF38 500E CE14 91F7 1C12 09B4 // Keyserver: wwwkeys.eu.pgp.net Key-ID: 1C1209B4
