I'd like to set up a machine with 10 or 12 discs, but SATA controllers which supports that amount of drives are hard to get for a "reasonable" price. However, I've recently learned about port multipliers, and that certain SATA controllers with, say, 2 ports can support more than the actual number of ports.

However, how do I connect 10 drives to a SATA controller with only 2 ports? Which cable to I use for this? For instance, the HighPoint RocketRAID 620 supports up to 10 drives but has only 2 SATA ports...how do I physically connect 10 drives to this controller?

Oh god. Please don't use RocketRAID or SATA in a server. –  MDMarra Jan 3 '13 at 21:13
Get a SAS card and Expander. A LSI SAS HBA can be found on eBay for at little at $50 for older models or a 2911 model for ~$250. HP's SAS Expander (widely used in hobbiest storage arrays) can be found for <$300. Add cables and whatnot... For <$650 you can have 24 or more SAS ports (which support 6Gb SATA as well) and an aggregate throughput where the PCIe bus is the bottleneck. SATA Port Multiplies are notable for being slow and prone to compatibility problems. –  Chris S Jan 3 '13 at 21:22
To expand a bit on why to MDMarra's comment: Most SATA disk + failure of a single drive on a port multiplier == all drives on that PM unusable. Not nice for a server. –  Hennes Jan 3 '13 at 21:22
@Hennes : thanks for elaborating MDMarra's answer. I didn't know that. Thanks. –  sbrattla Jan 3 '13 at 21:31
@MDMarra : thanks for your comment. It's is indeed a server, but it's a server where storage is the only concern. That's why I'm looking into port multipliers. Howevever, I'll have a look at what Chris S wrote. –  sbrattla Jan 3 '13 at 21:32
