Nutanix VirtIO for Windows

Nutanix has released VirtIO for Windows. I am still seeing people finding versions off the web which is fine but it could lead to other support issues. The Nutanix version is a qualified distribution of Windows drivers for AHV’s paravirtual devices. The automatic installer makes it pretty easy for anyone to get started. Both an ISO and MSI are available.

You can download the drivers from the support portal.


STAY-FIT: Getting Ready For What Is Next in Prism

Nutanix Engineering has been working at a blistering speed to further the ease of use of the XCP platform. Nutanix was accepted to present at the BayLearn Symposium this last October to highlight it’s new machine learning algorithm being used in search and capacity trending. I sat in a engineering meeting getting an overview but lets be honest, a lot of it was over my head. Like most things at Nutanix it’s great that the end user doesn’t need to know the inner working to use the product; however, we are always willing to share, case in point the Nutanix Bible.

From a high level – “STAY-FIT: Seasonal Time Series Analysis and Forecasting using Tournament Selection” is an algorithm to forecast “yearly”, “quarterly”, “monthly” and “other” time series. We also used STAY-FIT to forecast our customer data. STAY-FIT predictions outperformed the best existing algorithm (THETA) with testing demoed at the Baylearn conference.

• Self learning from data and capable of optimally choosing the right set of models for forecasting;
• Scalable to handle web-scale applications;
• Capable of online real-time predictions.

STAY-FIT is the core algorithm for predictive analysis that’ll be shipped as part of Capacity Analytics on Prism Central in the next release. You can check out the below demo that was presented live at our first user conference. More Nutanix goodness to come.
