iSCSI strikes back in Nutanix storage

30 June 2015
5 comments

Reading Time: 3 minutesHistorically, Nutanix was built around iSCSI but then they have add the ability to run NFS as well as other front-end IP based protocols. Starting from version 2.5, NFS/NDFS has become the preferred protocol for the Nutanix cluster. Although the Nutanix Distributed File System (NDFS) is stretched across all nodes and build on the pool of each local storage resource, all I/O for a VM is served by the local CVM. The storage can be presented via iSCSI, NFS or SMB3 (introduced in NOS 3.5) to the hypervisor from the CVM (not only the local, […]

Nutanix Erasure Coding-X

Reading Time: 3 minutesOne of the big announces at the .NEXT Conference, was the introduction of erasure coding across nodes (in RAIN configuration) in Nutanix Operating System (NOS) version 4.1.3 (actually it’s a tech preview). Nutanix Erasure Coding–X (EC-X) is a proprietary, native, patent pending, implementation of Erasure Coding. With EC-X, Nutanix customers are able to increase their usable storage capacity by up to 70%. As written in a previous post, Erasure Coding (EC) is a way to implement data proctection in storage systems instead of using RAID techniques.

Reading Time: 4 minutesWhen you talk about data protection against hardware failure in storage system, probably RAID (Redundant Array of Independent Disks) is the first technology that you think. RAID could be hardware or software based, and in the second case it can be implemented (with functions similar to RAID, but not necessary the same) also at the filesystem level (think about ZFS, for example). But with the new hard disk drive (HDD) capacities edging upwards (6TB HDDs are now available) the traditional RAID is becoming increasingly problematic both for the rebuild time and the bottleneck related to each single […]

Book review: VMware vRealize Orchestrator Cookbook

24 June 2015

Reading Time: 3 minutesOrchestration in VMware environments is something still not so well explored and explained. Historically there was only vCenter Orchestrator from one side (if you are looking something at high level) and scripting from the other (if you know PowerShell or other scripting languages). Now for the first part there is vRealize Automation, but still the Orchestrator part could be necessary (for example to use vRealize Automation with VMware NSX). The book “VMware vRealize Orchestrator Cookbook” has the ambition purpose to explain how to master the configuration, programming, and interaction of plugins with Orchestrator to efficiently […]

Reading Time: 4 minutesVMware vCenter Server is a critical component in a vSphere environment, because is needed to provide some cluster functionality. A good design and deployment (that are different from version 5.x and 6.0) are important to avoid possible issues. And, of couse, a good availability of this kind of service. Troubleshoot this component is not always simple and there are a lot of VMware KB articles, but not a good single resource from where start in this kind of tasks. The purpose of this book is really clear from the title itself (vCenter troubleshooting) and the […]
