We are looking for a ~32T external storage solution for two 48-core AMD servers. These will be used for a small Linux OpenVZ cloud for CPU intensive web-servers and data warehousing. Dual path with automatic fail-over is pretty much a must. Hopefully the enclosure and the SAS controller would cost around $9k and 16 drives around $4k.
Promise and Infortrend
We initially looked at Promise's VTrak E610sD: http://www.promise.com/media_bank/Download%20Bank/Manual/VTrak_E-Class_PM_v3.2.pdf (page 35 shows the topology that we would want)
A college suggested Infortrend's EonStor DS S16S-R2240: http://www.infortrend.com/products/models/ESDS%20S16S-R2240
Has anyone had experience with these systems?
What are some alternatives to the above Promise and Infortrend SAS product for a two server web+db cloud application?
This could be a good option: http://www.raidinc.com/xanadu_230.php
Would something like this also work? https://www.thinkmate.com/System/STX_JE16-0300/14991
