The modelling software predicts the impact both in terms of performance and capacity, below is an example of running through thisĪlso modelled is the impact on CPU and cache As a storage admin I really like the sound of this as so often we don’t know what the impact of an additional workload will be until it’s deployed. Nimble Resource planner allows load modelling. The Nimble storage platform also benefited from a couple of InfoSight enhancements. We’ve discussed this in detail previously including how to implement it, but in short this is free for customers and allows deep insights into your VMware environment such as being able to find VMs with the highest resource utilisation. First up was 3PAR performance insights which allows a performance view of not only your storage but also the VMware layer. There was a number of announcements around the InfoSight platform. Phillip Sellers has written an in-depth piece looking at the addition of SCM to Nimble and 3PAR. The additional cache creates quicker response times and also reduces the load on back end disks as the amount of IO served served here is reduced. Other vendors such as Pure have added NVMe drives into the system but HPE have focused on adding the NVMe storage within the controller as they believe that the key bottleneck in flash systems is at the controller level and not disk. The Intel Optane device will be NVMe connected and act as an extension to the onboard controller cache. Intel have developed their Optane product which sits in this middle ground of performance and cost between SSD and NAND flash. DRAM is fast memory but does not scale and is expensive, NAND flash does scale but does not deliver the same performance. Storage Class Memory memory (SCM) was intended to bridge the gap between DRAM and NAND flash found in current generation SSD’s. Storage class memory has been announced for 3PAR and Nimble. In this post we will run through the announcements. Last week at HPE Discover there was a series of storage announcements for the 3PAR and Nimble platform plus more.
