I'm looking at putting together a new box, mostly for storage. But it will probably run some virtual machines, and be used for some regression testing of backup software and for developing various website. The box will be sitting in my basement, not in a data center.
I've been looking at the components, I'm looking to order within the next week or two. The system will be running FreeBSD 9. The main OS will be installed on two SSDs and the main storage will be spread across 8x2T HDDs clustered together into a raidz2 ZFS array.
Here are the components I'm considering. The links below are all Newegg, and I like dealing with them.
The SYBA SD-PEX40054 PCI-Express 2.0 x4 SATA III (6.0Gb/s) HyperDuo 4-port RAID Controller Card is a solid budget-price choice. It has a true port-multiplier for attaching many drives in JBOD mode as well as a new feature called Hyper-Duo. This feature allows you to use an SSD and a HDD together with the operating system installed on an HDD and the SSD is used as a cache for all frequently accessed material including the operating system, applications and any data that's "hot". Use of a 60GB or larger SSD is ideal and will make the system faster and more responsive. All original material remains on the HDD and is, of course, saved/updated as you work.
