Exclusive product review: Infortrend EonStor B12S delivers big with small-form-factor drives
Built around 2.5-inch drives, EonStor B12S storage array yields space and energy savings without skimping on performance and featuresFollow @infoworld
Power performancePerformance-wise, the EonStor B12S fared well, rivaling results I've seen from arrays with 3.5-inch drives that use similar technology. This didn't surprise me in the least. I was, however, surprised by just how low the B12S's power consumption proved to be. When idle (i.e., while neither reading nor writing data), the B12S consumed a mere 235 watts, remarkably less than the 380 watts I have measured on arrays with 3.5-inch drives and similarly redundant, 12-drive configurations. Another interesting fact is that the workload doesn’t add much to the baseline, only a few watts more. In fact, the increment is almost perfectly linear with the block size increase, with a few spikes when the cooling modules of the array start spinning the fans faster, which happened, for example, when the room temperature would temporarily rise a degree or two above 75 F. Even at the highest stress level I measured -- during sequential writes of 64K blocks -- the B12S drew a mere 254 watts. See my Iometer results at various block sizes and their corresponding power consumption figures.
Infortrend offers an interesting approach to pricing: Unlike other vendors' arrays, Infortrend's enclosure doesn't mount drives with proprietary connections. Thus, you can purchase the enclosure (the one I tested costs just under $8,000), then procure your own drives separately.
I enjoyed reviewing the Infortrend EonStor B12S and I would not hesitate to recommend it for consideration for shops where its capacity and other features fit your requirements. Boasting performance in the same ballpark as traditional arrays, a power draw that is roughly 60 percent less, and an overall form factor just half the size, the B12S can be an offer too good to pass on.
