A common misconception is that Nimble Storage cannot be very fast because they use 7200 rpm HDDs, however their proprietary CASL filesystem uses ‘slow’ HDDs like no other system does. The CASL uses a number of techniques to optimise HDD performance to achieve up to 10,000 IOPS from a single 7200 RPM HDD! Therefore a Nimble Storage array consisting of only twenty-one 7200RPM drives and only six SSDs can deliver up to 270,000 IOPS. All flash array performance without the compromise in capacity over cost.
Yes, we know what you are thinking and it does sound unbelievable, so we request you let us demonstrate this amazing feat and explain exactly how this is achieved.
