Building Private Cloud Storage – HCI or Dedicated Array?

Last week Martin and I had a great conversation with Kieran Harty, CTO of Tintri Inc.  Tintri sells a range of storage appliances that deliver VM-focused shared storage.  Rather than talk exclusively about products, we discussed how storage arrays are evolving to meet the needs of private cloud. Requirements The NIST definition of public cloud… Read more »

Fixing the Problem of I/O With Parallel Computing – DataCore MaxParallel

The idea of improving the performance of applications through the use of parallel computing isn’t a new concept.  Look back 50 years and we can see that Amdahl’s Law shows how to predict the performance improvement that can be achieved by using multiple processors.  You can find details of Amdahl’s Law on Wikipedia, but essentially… Read more »
