The good news is that even though the answer to your question is "no", it doesn't matter because it sounds like what you are doing is a piece of cake :)
Given how cheap hardware is, and how modest your requirements sound, I expect you could build multiple custom systems for the cost of an EMC system. Even that pogolinux stuff is overshooting the mark compared to what a custom system might be. Price is typical too, considering they're trying to sell 1TB drives for $260 when similar drives are less than $150 for regular folks. The manageability of nexentastor software might be worth it to you over a solaris terminal, but for a small shop with one machine and one guy who knows it well, you might just do the hardware from scratch :) Especially given what there is to know about ZFS and your use case, such as being able to use slower disks with more RAM and a SSD ZIL cache to produce deceptively fast results. If cost continues to be a concern over performance, also consider that these pre-made systems are not designed for power conservation at all. They're still shipping old inefficient processors and other such parts in these things, hoping to take advantage of IT people who don't care or know any better. A custom system could potentially cut the total power cost in half... > <div id="jive-html-wrapper-div"> > <div dir="ltr">Hi everyone,<br><br>We're a small > Linux shop (20 users).
