Hi everyone,
i need suggestions and hints about an redundant
storage-system.
My requirements are:
a Storage that is available via Network, flexible in scalation,
and must be redundant, and cheap if possible....
My Own suggestion was this scenario:
2 boxes very cheap for ~300$
2 or more SATA-II-Controller ~30$(SIL)
4 or more Disks with 200-250GB ~100$/piece
You've obviously chosen to prioritize cheap above anything else with these
recommendations. :-) You simply can't spend less than a grand and expect
to get even one decent fileserver, much less a pair of machines.
Do not get a Silicon Image SATA controller.
If you want to value redundancy and the ability to scale, you ought to look
at NAS or SAN systems, such as NetApp filers, or maybe even an Apple Xserve
and a Fibre-channel switch.
Even if you're not willing to pay that much, you should at least consider
what those solutions offer for their pricepoints, and then decide what your
data is worth to you and what your requirements should be.
At the very least, get a multiport SATA RAID controller with a decent-sized
RAM cache of its own and an internal battery to keep the drives going until
that cache can be flushed. As well as an external UPS, right...?
