Two weeks ago I had the pleasure to have an one to one phone call with Alex Bakman, Founder and CTO of VKernel.com. We discussed about a new FREE tool that VKernel was about to release called StorageVIEW.
The news was under embargo until Monday, June 21st so I could not publish anything yet about it but Alex kindly sent me a copy of the tool few of days before the announcement and I could play with it enough time in my home lab to come back with a series of blog posts. This is the first part.
First let me give you a bit of a background here. VKernel has been founded in April 2007 and they shipped their first product in April 2008. Since then the company released many tools for each stage of a VM life cycle:
- Deployment -> Capacity Modeler – shows optimal VM deployment location,
- Production -> Capacity Analyzer – Analyzes current and future performance issues,
- Optimization -> Optimization Pack – Optimize environment to delay additional hardware purchases
- Cost Visibility -> Chargeback – Cost visibility and reporting,
- Retirement -> Optimization Pack – Locate abandoned VMs and reclaim all resources.
VKernel has a culture of free tools as well, some of them I’ve been using for years now at customer sites and also in my own home lab, name it: Capacity View and AppVIEW. Even the famous Kendrick Coleman’s Top 10 Free vSphere ESX Tools and Utilities rank two of the VKernel Free Tools; Capacity Modeler at 6th place and Search MyVM at 5th place.
So now let’s talk about StorageVIEW. The goal of this free tool is to provide you with latency information as indicator of problem with host/datastore pair connected through FC, iSCSI and also NFS for up to five host to datastore links with the greatest latency.
For those of you still running ESX3.x and/or vSphere4.x and are not willing to upgrade to vSphere4.0 Update2 just to get the ESXTOP’s NFS statistics, you can use VKernel’s StorageVIEW to get statistics for your NFS datastores. The granularity is even a step further than ESXTOP in the way you can see NFS statistics per VM!
