Microsoft MVP award reconfirmation

Reading Time: 2 minutes

According to Microsoft, Microsoft Most Valuable Professional (MVP) award is given to “exceptional, independent community leaders who share their passion, technical expertise, and real-world knowledge of Microsoft products with others”.

The awarded are people who “actively share their … technical expertise with the different technology communities related directly or indirectly to Microsoft”. An MVP is awarded for contributions over the previous year.

Is more than an award (or accreditation) instead of certification and is quite similar (in the concept) like other “community” award, like the VMware vExpert.

iSCSI strikes back in Nutanix storage

Reading Time: 3 minutes

Historically, 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, but also from all CVMs).

One 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.

Erasure Coding and RAIN

When 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 disk.

Parallels is a well know company in the virtualization ecosystem and has some interesting solutions: Parallels Desktop 10 for Mac (to run Windows and other OSes on your Mac), Parallels Access (a simple remote access to your Windows or Mac computer from anywhere), Parallels Mac Management for Microsoft SCCM (able to extend your existing SCCM infrastructure to discover, enroll, and manage Mac computers the same way you do PCs, all through a single pane of glass), all 2X Software solutions and products (Parallels has acquired this company on Feb 2015) and Odin (formally the cloud service called Parallels Service Provider Business).

If you have a Mac, probably it’s a vendor that you have to consider for their solutions and products.

Book review: VMware vRealize Orchestrator Cookbook

Orchestration 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 automate your VMware infrastructure.
