Quick Thought: VMUG is now part of DTUC

I awoke this morning to the news that an announcement was made at DELL|EMC World that VMUG had been rolled into a the recently formed Dell Technologies User Community (DTUC – doesn’t quiet roll off the tongue now does it?) …I also awoke to a lot of VMware community backlash on Twitter not only in response to the news but also in the way in which it was not communicated to the existing local VMUG leadership and steering committee members.

From the reaction i’ve seen, most people are fairly ticked off with the fact that almost everybody found out about this through public channels…mainly Twitter. It’s worth watching the video below to get an overview of the changes from the VMUG President and CEO as it does go some way to clarifying the what’s what of the announcement.

Just to clarify, VMUG is not changing it’s name to DTUC.

My Take:

I think everybody knew that VMUG was in trouble from an organisational standpoint with a lot of changes during the first few months of 2017 and some interesting moves around the removing of Nutanix staff from leadership role. So this news isn’t a total surprise however for me, the one key ingredient that VMUG offered is now well and truly in danger of being wiped away…and that is it’s relative independence.

The VMUG community was born out of the technology ecosystem that grew around VMware’s success in the virtualization market and it meant that all of VMware’s technology and alliance partners where given a seat at the table in terms of event sponsorship and presentations. It was a place equally where smaller startup’s could come and talk about their new technology solutions and where the more established vendors could talk around why there where still cool and relevant.

Now, with DELL|EMC plus VMware product portfolio my fear is that finding sponsors will become even more of a challenge as it has been worldwide for the last 12 to 18 months. This is an interesting move but again, but not a surprising one given what I’ve seen with my involvement in VMUG over the past two years. It’s not all doom and gloom though as I feel the VMUG UserCons are still brilliant events as was the case with the recent ones held in Sydney and Melbourne.

Time will tell how this plays out, but there is one thing I believe the wider VMware community doesn’t want to see drop off or disappear…and that is the community it’s self!

vCloud Air and Virtustream – Just kill vCloud Air Already?!?

I’ve been wanting to write some commentary around the vCloud Air and Virtustream merger since rumours of it took place just before VMworld in Auguest and I’ve certainly been more interested in the whole state of play since news of the EMC/VMware Cloud Services spin off was announced in late October…the basis of this new entity is to try and get a strangle hold in the Hybrid Cloud market which is widely known to make up the biggest chunk of the Cloud market for the foreseeable future topping $90 billion by 2020.

Below are some of the key points lifted from the Press Release:

  • EMC and VMware  plan to form new cloud services business creating the industry’s most comprehensive hybrid cloud portfolio
  • Will incorporate and align cloud capabilities of EMC Information Infrastructure, Virtustream and VMware to provide the complete spectrum of on- and off-premises cloud offerings
  • The new cloud services business will be jointly owned 50:50 by VMware and EMC and will operate under the Virtustream brand led by CEO Rodney Rogers
  • Virtustream’s financial results to be consolidated into VMware financial statements beginning in Q1 2016
  • Virtustream is expected to generate multiple hundreds of millions of dollars in recurring revenue in 2016, focused on enterprise-centric cloud services, with an outlook to grow to a multi-billion business over the next several years
  • VMware will establish a Cloud Provider Software business unit incorporating existing VMware cloud management offerings and Virtustream’s software assets — including the xStream cloud management platform and others.

I’ve got a vested interest in the success or otherwise of vCloud Air as it directly impacts Zettagrid and the rest of the vCloud Air Network as well as my current professional area of focus however I feel I am still able to provide leveled feedback when it comes to vCloud Air and the time was finally right to comment after yesterday evening comming across the following LinkedIn Post from Nitin Bahdur

It grabbed my attention not only because of my participation in the vCloud Air Network but also because the knives have been out for vCloud Air almost before the service was launched as vCloud Hybrid Services. The post its self from Nitin though brief, was suggesting that VMware should further embrace it’s partnership with Google Cloud and just look to direct VMware Cloud customers onto the Google Cloud. The suggestion was based on letting VMware Orchestrate workloads on Google while letting Google do what it’s best at…which was surprisingly Infrastructure.

With that in mind I want to point out that vCloud Air is nowhere near the equal of AWS, Azure or Google in terms of total service offerings but in my opinion it’s never been about trying to match those public cloud players platform services end to end. Where VMware (and by extension it’s Service Provider Partners) does have an advantage is in the fact that in reality, VMware does do Infrastructure brilliantly and has the undisputed market share among other hypervisor platforms therefore giving it a clear advantage when talking about the total addressable market for Hybrid Cloud services.

As businesses look to go through their natural hardware refresh cycles the current options are:

  • Acquire new compute and storage hardware for existing workloads (Private – CapEx)
  • Migrate VM workloads to a cloud based service (IaaS – OpEx)
  • Move some application workloads into modern Cloud Services (SaaS)
  • Move all workloads to cloud and have third parties provide all core business services (SaaS, PaaS)

Without going into too much detail around each option…at a higher level where vCloud Air and the vCloud Air Network has the advantage in that most businesses I come across are not ready to move into the cloud holistically and for the next three to five years existing VM workloads will need a home as businesses work out a way to come to terms with an eventual move towards the next phase of cloud adoption which is all about platform and software delivered in a cloud native way.

Another reason why vCloud Air and the Air Network is attractive is because migration and conversion of VMs is still problematic and a massive pain (in the you know what) for most businesses to contemplate undertaking…let alone spend the additional capital on. A platform that offers the same underlying infrastructure as what’s out there as what vCloud Air, the vCloud Air Network partners and what Virtustream offers should continue to do well and there is enough ESXi based VMs out there to keep VMware based cloud providers busy for a while yet.

vCloud Air isn’t even close to being perfect and has a long way to go to even begin to catch up with the bigger players and VMware/EMC/DELL might well choose to wrap it up but my feel is that that would be a mistake…certainly it needs to evolve but the platform has a great advantage and it, along with the vCloud Air Network should be able to cash in.

In the next part I will look at what Virtustream brings to the table and how VMware can combine the best of both entities into a service that can and should do well over the next 3-5 years as the Cloud Market starts to mature and move into different territory leading into the next shift in cloud delivery.

Quick Tip: Re-IP VNX5300 …or any VNX

Our Operations Team where faced with an unfamiliar situation a few weeks back where we needed to re-ip an EMC VNX5300 that had it’s warranty extended and was relocated to a new Availability Zone. Generally once warranty terms and finance expire old SANs like this get returned to sender to be replaced by a newer model or new storage of some description.

As a change of topic on this blog I thought it would be good to document the process as there isn’t a lot of info out there on what needs to be done apart from the official EMC VNX Documentation locked away behind the EMC Client Portal.

In the example below we are initially concerned with the Control Station and Storage Processors of the VNX and we will change their IPs via SSH and not via Serial as suggested in the EMC guides. I would still suggest doing this via Serial if you have easy physical access to the SAN however in my case it was at the other side of the country. Networking wise I had a dual homed VM which had Network Adapters in each VLAN/PortGroup to allow the change from old to new.

 Component IP Address Values  Existing IP  New IP
Control Station 0 IPv4 IP Address:
IPv4 Subnet:
IP4v Gateway:
10.1.4.5
255.255.255.0
10.1.4.1
10.2.5.50
255.255.255.0
10.2.5.1
Control Station 1 IPv4 IP Address:
IPv4 Subnet:
IP4v Gateway:
10.1.4.6
255.255.255.0
10.1.4.1
10.2.5.51
255.255.255.0
10.2.5.1
Storage Processor A IPv4 IP Address:
IPv4 Subnet:
10.1.4.6
255.255.255.0
10.2.5.6
255.255.255.0
Storage Processor B IPv4 IP Address:
IPv4 Subnet:
10.1.4.7
255.255.255.0
10.2.5.7
255.255.255.0

Change IP Address of Primary Control Station:

  • SSH to CS0
  • Change CS0 IP to the new value

Change IP Address of Secondary Control Station:

  • Failover CS0 to force CS1 as Primary

  • This Operation can take about 15 minutes to complete and can be monitored on CS1 by running the command below

  • During the failover you will see the status of slot_0 and slot_1 swap over while slot_0 goes offline
  • Once slot_0 comes back online SSH into the new IP to confirm access of CS0
  • SSH to CS1
  • Change CS1 IP to the new value

  • Failover CS1 to force CS0 as Primary

  • After another 15 minutes both CS IPs have changed and CS0 is again Primary

Change IP Address of Storage Processor A and B from CS0:

  • The script below will do all the work and the output given is extremely useful as it goes along.
  • Once that’s finished, check the status of the Storage Processors

From here you can access Unisphere from the new SP IP Addresses and go on to reconfigure the rest of the VNXs settings.
