Memory Management in ESXi 6


Post by Joseph Griffiths (thank you)

A good friend recently reviewed the what’s new in vSphere 6 course and has some questions.  That generated a number of really great discussions and this blog article.   At about the same time I had a customer asking why their virtual machine was showing ballooning even thou there was no memory pressure.   This generated some research and though organization into this article

VMware VSAN for ROBO Two Node 10 GbE cross-connect support


Good post by Vladan Seget (thank you)

I somehow ignored this information but I think that it’s very useful to share, especially if you’re navigating the SMB or very SMB sector. In fact VMware VSAN for ROBO Two Node 10 GbE cross-connect support. So you have the possibility to cross connect ROBO nodes, via low cost 10GbE option and have a great performance because you’ll have dedicated VMkernel interface for VSAN traffic.

Protecting NFS storage on vSphere using Veeam virtual proxies

Good post by Luca Dell’Oca (thank you)

Since Patch 3 of Veeam Backup & Replication v7 (build there has been a new mode to manage hotadd backups over NFS, available via a registry key. Per the original release notes:

“Intelligent load balancing can now be configured to give preference to backup proxy located on the same host using the EnableSameHostHotaddMode (DWORD) registry value.”

I’ve kept this post on hold for a while, since with the upcoming v9, DirectNFS will be a much better option than virtual proxies to backup virtual machines running on NFS shares. But there are situations where this key may be still needed, like people still wanting to use virtual proxies against NFS. So, what is this key, and what you can do with it?

New Microsoft Exchange 2013 on Virtual SAN 6.1 Reference Architecture

Good post by Rawlinson Rivera (thank you)

A new Microsoft Exchange 2013 on Virtual SAN 6.1 is now available on the VMware Virtual SAN product Resource page.

This new VSAN-Exchreference architecture walks through the validation of Virtual SAN’s ability to support Microsoft Exchange 2013 designed to satisfy high IOPS mailbox configuration with Exchange Database Availability Groups (DAGs). The reference architecture is based on a resilient design that covers VMware vSphere clustering technology and Exchange DAG as well as data protection and recoverability design of Exchange Server 2013 with vSphere Data Protection and vSphere Site Recovery Manager.

Pure gives its flash boxes some 3D TLC

Post by Chris Mellor (thank you) over at El Reg

Pure Storage wants to be its flash array customers’ best friend forever with announcements lowering flash storage cost and improving its availability.

The Silicon Valley biz is now supporting 3D TLC flash, the three-bits-per-cell stuff that has an endurance long enough for enterprise use. Other flash array suppliers using this technology include HP Enterprise, Kaminario, and Dell.

Backup is not Archive

Good post by Joseph Ortiz (thank you)

In order to protect their data while dealing with explosive data growth, many organizations have started backing up their data to the cloud in an effort to reduce their storage and data center costs as well as obtaining data redundancy without the need to maintain a separate physical DR site. Many also mistakenly believe that these additional backup copies qualify as archive copies. Unfortunately, they do not.

VMware Metro Storage Cluster Overview

Good post by Derek Hennessy (thank you)

VMware Metro Storage Cluster

VMware Metro Storage Cluster (vMSC) allows vCenter to stretch across two data centers in geographically dispersed locations. In normal circumstances, in vSphere 5.5 and below at least, vCenter would be deployed in Link-Mode so two vCenters can be managed as one. However, with vMSC it’s possible to have one vCenter manage all resources across two sites and leverage the underlying stretch storage and networking infrastructures. I’ve done previous blogs on NetApp MetroCluster to describe how a stretched storage cluster is spread across two disparate data centers. I’d also recommend reading a previous post done on vMSC by Paul Meehan over on The idea behind this post is to provide the VMware view for the MetroCluster posts and to give a better idea on how MetroCluster storage links into virtualization environments.

Image-level backups can be done even without CBT

Good post by Luca Dell’Oca (thank you)

Lately, different bugs involving VMware CBT in vSphere 6 have created some justified concerns among users. But there are ways to guarantee successful backups even in these conditions.

Image-level backups are still the way to go

Yes, vSphere 6 is having some issues with CBT in vSphere 6.

Since its introduction back in the days of vSphere 4.0, CBT has been the cornerstone to allow fast incremental backups. CBT (change block tracking), as the name says, is a log of changed blocks of a virtual machine that vSphere registers in a file. Different data protection solutions can read this file, list which blocks have been changed since a given timestamp (usually the previous job execution), and thanks to this easily retrieve only those blocks from the storage instead of having to do a full backup every day.

The Storage Requirements for 100% Virtualization

Post by George Crump (thank you)

After a rapid move from test to production, virtualization of existing servers in many companies seems to slow down. While it is true that most data centers have adopted a virtualize first philosophy, getting those older, mission critical workloads virtualized seems to be a thorny issue. These applications are often at the heart of an organization’s revenue or customer interaction and tend to be unpredictable in the resources they require. This is especially true when it comes to storage and networking.
