Coniguration
There is no one-step guide to configure these multipliers. Some need to be configured
using software in Windows or Linux, while others may have DIP switches that
configure the multiplier to a specific configuration.
Addonics is a well-known and fairly easy-to-source multiplier. You will need to
search around on the Internet, online auctions, and shops for these. The prices are
around the same as the Pi; but if you are looking for redundant storage, then these
are the cheapest options you will find.
Massive storage
If you are looking to create a really massive storage, you can easily daisy chain a
multiplier with another, sometimes up to three or four times. Recently, Addonics
developed another device that can be daisy chained infinitely!
Let's assume that we can daisy chain up three levels and we use 2 TB hard drives.
We configure all the multipliers to span data across all drives with no redundancy;
that is, 5 times 5, times 5. We end up with 125 usable SATA ports and a total of 250
terabytes of storage. This figure is highly impractical for home users, because all
those hard drives consume a lot of power. There are people who have hard drive rigs
like these at home, so I would think using six multipliers to achieve 25 SATA ports
would be a completely viable and cheap option for some readers! The following
figure is a simple example of how to replicate 1 SATA port into 5 more Ports using
SATA port multipliers:
