A closer look at Maxta

maxtaMaxta are another storage vendor that I managed to get talking to at this years’ VMworld conference in San Francisco. Although they were present at last year’s VMworld, they only announced themselves in earnest last November (11/12/13) with the release of the Maxta Storage Platform (MxSP). I spent some time with Kiran Sreenivasamurthy, Director of PM & PMM at Maxta, and he was very open in sharing details on the Maxta product.

If you read the blurb on Maxta on the VMworld sponsor/exhibitor list, it states that they eliminate the need for storage arrays, provide enterprise class data services and has full virtualization integration from UI to data management.

So on the face of it, Maxta is another converged solution, similar in many respects to VMware’s own Virtual SAN, Nutanix, Simplivity, etc. So what makes Maxta so different? Kiran shared his views with me here.

VSAN Troubleshooting Case Study

vsan-vmware-virtual-san-boxI have been doing a bunch of stuff around disaster recovery (DR) recently, and my storage of choice at both the production site and the recovery site has been VSAN, VMware Virtual SAN. I have already done a number of tests already with products like vCenter Server, vCenter Operations Manager and NSX, our network virtualization product. Next up was VCO, our vCenter Orchestrator product. I set up vSphere Replication for my vCO servers (I deployed them in a HA configuration) and their associated SQL DB VM on Friday, but when I got in Monday morning, I could not log onto my vCenter. The problem was that my vCenter was running on VSAN (a bit of a chicken and egg type situation), so how do I troubleshoot this situation without my vCenter. And what was the actual problem? Was it a VSAN issue? This is what had to be done to resolve it.

VMworld 2014 – Storage News Part 1

vmworld-2014-active-banner-v4Yesterday was my first day at VMworld 2014. As usual with this event, there are simply so many interesting announcements that it is hard to keep track. However, for me, there were a few things which stood out in the storage space worth calling out. These are specifically VMware focused products and features. I know that many of our partners have also made announcements in the storage space, but for today I concentrated solely on VMware. There are the two that really caught my attention.

Storage Vendors to check out at #VMworld 2014 (SFO)

Last year I published a list of storage vendors and partners that I was planning to check out at VMworld 2013. This year is no different, with a number of new arrivals on the storage scene, as well as some super new cool products from many of VMware’s partners. Whilst this is no means a definitive list of what’s on show, these are the ones that I am particularly interested in checking out this year.

VSAN Part 26 – Does Disk Size Matter?

I was involved in an interesting thread recently with one of our VSAN partners regarding disk sizes used in VSAN, and what impact smaller drives may have. In an earlier post, I discussed reasons why VSAN would stripe a VMDK storage object even though a stripe width was not requested in the VM Storage Policy – Why is my Storage Object striped?

In that post, I highlighted the fact that if the VMDK storage object is too big to fit onto the free space of a single hard disk, then it will automatically be striped across multiple hard disks. However there is another VSAN object that disks size may also impact – the VM Home Namespace.

Network Virtualization (NSX) and vSphere Data Protection Interop

NSX-300x206In this third article in the series of backing up the vCloud Suite, we turn our attentions to NSX, VMware’s Network Virtualization product. Before starting, I should point out that NSX has a recommended way of backing up and restoring configuration information via the use of an FTP server, which you need to configure in your infrastructure to hold this exported metadata. However this exercise looks at how you might be able to use VDP to back up and restore an NSX configuration using image level backups. Once again, I wanted to see whether I could restore the NSX environment to a particular point in time, in-place and also by restoring to a new location. This is the same infrastructure that I used for backing up and restoring vCops and backing up and restoring vCAC and VCO. On this occasion, I was using NSX version 6.0.4, vCenter 5.5U1 and VDP version 5.5.6.46.

Heads Up! VASA Storage Providers disconnected – VSAN Capabilities Missing

I’m a bit late in bringing this to your attention, but there is a potential issue with VASA storage providers disconnecting from vCenter resulting in no VSAN capabilities being visible when you try to create a VM Storage Policy. These storage providers (there is one on each ESXi host participating in the VSAN Cluster) provide out-of-band information about the underlying storage system, in this case VSAN. If there isn’t at least one of these providers on the ESXi hosts communicating to the SMS (Storage Monitoring Service) on vCenter, then vCenter will not be able to display any of the capabilities of the VSAN datastore, which means you will be unable to build any further storage policies for virtual machine deployments (currently deployed VMs already using VM Storage Policies are unaffected). Even a resynchronization operation fails to reconnect the storage providers to vCenter. This seems to be predominantly related to vCenter servers which were upgraded to vCenter 5.5U1 and not newly installed vCenter servers.
