vSphere Metro Storage Clusters
Duncan Epping
HA protects against:
- host failure
- host network isolation
- permanent loss of datastore
- VM crashes
- guest OS crash / hang
HA is OS and application independent
HA Agent is now called Fault Domain Manager and moves to a single master, multiple slave model (from 5 master model). In the event of loss of single master, slaves elect a new master. Heartbeating is still over the network, but now uses the datastore as an additional heartbeat to monitor. Network heartbeat is checked first, when this is lost the datastore heartbeat is checked.
vSphere Metro Storage Cluster (essentially a stretched storage cluster)
- hardware needs to be on the HCL
- HCLs for iSCSI, NFS and FC
- network is stretched across sites
- storage is stretched across sites
- essentially a federated HA solution
- single vCenter (which can be a VM in the stretched cluster of course, and this is a common use case)
- quicker than SRM to recover machines because it is essentially an HA activity
- max supported network latency is 10ms round trip time (RTT)
- vSphere Enterprise Plus licencing is required
- max supported storage replication is 5ms RTT
- good for relatively local failover across sync sites
- most storage hardware will support an async 3rd copy of the data
- uses DRS affinity groups per site to maintain multi-tier application performance using the "should" rules, not the "must" rules.
Capgemini Public and Hybrid Cloud - Service Brokering
Thoughts: Looks like a great idea to offer pre-packaged services. From what we saw today it looks like there's still a little way to go in completing the development and getting a real service offering to market. It has real potential, CG will need to focus on the largest market first to prove the model works, then they will have an extremely complex job building and maintaining all those interfaces and changes to those interfaces over time. I hope they can make it work as this has potential to be game changing in the market.
Introduction to Network Virtualisation with NSX
Eric Lopez
Straw poll of audience asking what type of cloud infrastructure is in place. No VCD users in the room, but a few using OpenStack.
Service providers (internal or external) want to:
- deploy applications at scale with little pre-planning
- have mobility to move workloads across geographies and providers
- flexibility to create and add L3 - L7 services
Currently VMs are linked to physical network features such as ACLs, IP addresses, VLANs etc. This means it is slow to make changes, placement of workloads is limited, there are hardware dependencies, operationally intensive and therefore expensive.
Treat NSX as though it is a network hypervisor equivalent to ESX - it places an abstraction layer between VMs and the physical network switches underneath. Brings hardware independence, allows VMs to be moved around without changing the underlying physical host network config and brings the operational benefits of virtualisation.
In and NSX network every host server only has 1 IP and 1 MAC address per server.
The NSX controller planer is an HA cluster on x86 servers and is out of the data path. Controls "thousands" of devices - but this was not quantified.
The NSX data plane is based on software switching in the host servers - vSwitch for VMware (NVS) and Open vSwitch for CloudStack and OpenStack (OVS). Every host in the NSX environment needs a vSwitch of the correct flavour and works with vSphere, KVM and XenServer hypervisors.
NSX manager is a vAppliance
Physical servers are connected through an host running Open vSwitch NSX Gateway
NSX is a tunnelling overlay using STT, GRE and VXLAN. It effectively adds another layer of L2 headers to each packet. Jumbo frames are required.
High Power Graphics And Virtualization - Testing The Protocols
The following types of GPU options are (or soon will be in the case of vDGA) be available for vSphere:
Throughout the discussion the terms VMware / PCoIP were interchanged freely, as were Microsoft / RDP and Citrix / HDX, with each solution being aligned to one vendor.
First to note is that RDP7 did not perform well under any circumstances other than a LAN.
For current formats (including RDP8), the results are VERY DEPENDENT ON THE PROTOCOLS AND CONNECTIVITY in use. It's not really possible to say "x is better than y" because it very much depends on the application protocols in use. Note that versions of protocols are important too. For example the latest version of HDX produces much better synchronisation between voice and video, but to achieve this it freezes occasionally to allow the catch up - so the video only element is now not as smooth as the previous version.
On a LAN all the protocols will take as much bandwidth as they can get access to. (e.g. up to 80Mbps for PCoIP, but RDP more efficient at 50Mbps).
Discussion: Lync video testing - nothing to done to date, but looking into it. Simulating users "is hard".

The Big Party
The format is now familiar - a very large room, 5 or 6 bars serving complementary drinks, pool tables, pinball machines, retro arcade games and then something a bit different, which this year was the option to go roller-blading alongside the hired dancers. Great mix that, roller-blading and free beer!
The bars offered plenty of choice - including cocktails mixed to order. I stuck to a few beers, being mindful of the need to get to the 9am sessions the next day. A big improvement, I thought, was keeping the party on site at the conference venue. There was a 90 minute gap between the end of the sessions and the start of the party - ideal to ensure that folks filled their time by walking the solutions exchange booths, and not wasting time on travelling between venues. The party was from 7pm to 10pm so there was no excuse for staying up too late! Well, not a VMWORLD excuse anyway. Food was burgers / wraps, sushi and puddings. Plenty of it too.
Entertainment was provided by dancers on roller skates, stilts or unusually dressed in interesting costumes or with ipads for faces, all backed by tunes from a DJ. First act was an all girl group called High on Heels that comprised DJ, vocalist, sax, violin and percussion. They did a really good job of covering classic and contemporary R&B, dance, soul etc., from Emile Sande to Black Box via Chaka Khan. Good stuff, and, for me at least, somewhat more talented that the main act. They also had a guy on stilts, covered in lighting and resembling Iron Man firing fire extinguishers just for the sake of it. Better than it sounds!
I lost my specs to Taio Cruz. Not sure if that's entirely true, but Cruz was up as the headline act. He sang to a backing track provided by a DJ. He did all 6 songs but I confess to not really spotting much difference between them. The crowd were hyped up by his presence, but at the beginning of pretty much every song I thought he was launching into Dynamite, but I was wrong until the last track. Still, I think I was in the minority as the crowd were very much enjoying themselves. There was a great part of the set when large illuminated balls were passed out over the crowd (these were balls, not balloons) and it was great fun to bat them around overhead. Except when one of them hit me on the back of the head, removed my specs and that was the last I saw of them as they were trampled underfoot by 2000 bouncing geeks. Ho-hum, the hazards of partying! Made the rest of my trip a bit tricky though, must remember to carry spares in the future.
VMware Virtual SAN
First fully attended session I've attended, and it is being repeated several times during the week.
Scale out storage in the hypervisor natively, not a virtual appliance
HDD, SSD, but requires SSD to perform well
Behaves just like shared storage with all the usual sphere features
Can apply policy based storage management
Distributed RAID, no RAID of physical disks required
Perf and capacity scales linearly as you add nodes to the cluster
Writes to multiple vmdk copies for HA
When deploying a VM:
- vsan checks where there is space for the number of images neede to be created in the array, keeps images separated according to policy
- writes go to all images simultaneously to the SSDs. All writes must complete before it is acknowledged
- data move to HDD a sync later
- if replication is required it is copied from SSD or HDD from the fastest available location
vMotion
- no change, VM moves around the cluster
- if a vMotion cases a performance issue then storage location automatically moved across vSAN whilst maintaining policies
Fault Tolerance
- loss of host - HA will restart vm as normal, waits 30 mins to see if host comes back up, if not vSAN will start creating new copies in the background whilst managing network traffic
Need min 3 servers in cluster.
Min 1 SSD and 1 HDD per host
Recommend 10Gb network
Assumption that virtual networking is in use
Server needs to be on HCL
<Suggested Workloads
- VDI
- Dev / test
- DR target
Performance
- claiming vSAN can deliver same VDI density as all SSD array
Thoughts:
- Great for workloads where compute : storage ratio is fairly constant, e.g. VDI
- if it performs as claimed it will be a game changer for some workloads
VCloud Hybrid Service
Deploying a VM is now straightforward, but adding the network, storage, firewall etc creates delay.
Extract, pool, automate is the mantra of the week
VMware services in 3 US data centres
UK available in Q1 2014
Focussing on virtual private cloud
5GHz CPU
20GB RAM
$2 per hour
10Mbps standard connection over secure tunnel or 1Gbps for virtual private cloud 10Gbps for dedicated cloud are available as dedicated lines
Data protection is an add-on service
DR as a service is available
Portal to make services available to business, including dynamic, status reports.
Shopping cart approach to purchase- multiple different pricing models
Data migration at start up is normally via physical NAS transfer.
For the hosting only you can manage using a browser. If you have existing comprehensive internal VMware environment then it is claimed to be easy to migrate vms to VMware vCloud Hybrid Services.
Thoughts: I remember asking VMware folks if they would be providing their own cloud services when they announced vCD - they said no as all the service providers would be buying vCD - this could be VMware's recognition that the service providers have largely chosen other routes?
Wednesday General Session
There are echoes of the previous 5 years of promises to move IT costs from 70% run to 70% investment. Virtualization was just the first step - as many of us knew at the time, vitualization solved a small part of the problem (space, power, hardware reduction, agility, hardware refresh etc.). Now all this can be automated.
NSX
- in addition to vitalizing the network the intention is to make server to server traffic more direct and efficient
- can move existing VMs by using motion
- someone should advise US companies about how scripted conversations are far too obvious. Maybe it works in the US, but not very cool in EMEA
VSAN
- demo of how easy it is to deploy
- adding a host to a cluster adds the storage in that host
- policies allow copies of vmdks and writes go to all copies. No ,mention of performance impact
- for DR the data is replicated off site. No mention of recovery method - needs further investigated
- in beta now, no mention of GA date
User Self Service
- IT need control through policy, security and automation
- one click user access to apps regardless of how it is delivered including XenApp in Horizon workspace
VCops
- automation of responses to predicted events based on policies, eg add VMs to a service that is maxed out
- connections into many other vendors' management tools
- can move workloads across service levels using vMotion and Storage vMotion
- health of system exposed to business through vCAC
Thoughts: after a few years of more of the same and lots of acquisitions that sat alongside rather than as part of the suite, VMware seem to have started to make significant steps into new areas and better integration- . IF it delivers on the promises and IF the licensing makes sense. OpenStack probably has a better chance than Microsoft to respond quickly.
Personally, there are still a couple of elephants in the room - adding the automation tools adds more stuff to manage, change control and maintain, and is the infrastructure really the bottleneck in most IT projects? I can see that infrastructure can be a bottleneck on doing more or less of what is already being done, but for the development of genuinely new business IP implemented on IT, infrastructure is much less likely to be a project delay.

Making the Most of Hybrid Cloud
Starting with a level setting.
Making analogies with how containerisation of the shipping industry.
vApp is the standardized container.
These vApps run on vmware based clouds: Att, blue lock, colt, csc, loch, singhtel, t-systems are available providers with services across 24 countries
Application choice when moving to the cloude is important- data security and location to meet compliance, service levels required - crucial to provide right sizing for security and service level requirements as over specifying is an expensive mistake
the closer to commodity the application stack is, the easier it will be to move to the cloud, eg email, sharepoint, web, ecomm
Ensure splitting of components can still perform over a link to other components in the cloud
Costs to migrate
- understanding internal tco is complex
- need to add bandwidth costs
- migration effort
- easiest if you have vApps of course
- use feasibility analysis (vmware consultancy service) including internal costs for comparison
Business value?
- give devs quick access and less time building environments
- agility ( particularly in agile dev env or peaky workloads)
- potentially lower cost of ownership
- avoid the grey economy of cloud outside IT control (survey says somewhere between 37 and 58%, depending on who you ask suspect or know this happens in their business.
Thoughts - the need to work out what is right to provision via a cloud seems to be the obvious analysis to do before making a decision. I think what is lacking is a clear methodology for making these decisions. Need cloud centre of excellence to manage this, design solution, deliver solution and manage contracts.
Of course Dell Multi-Cloud Manager will help once you have decided what steps to take into the cloud.
And to answer my earlier question, apart from recognising that out of control cloud services exist, the solution is very VMware focussed. The principles of making decisions applies generically.
Opening General Session
More interestingly, compared to the messaging when VCD was released VMware's messaging has changed from multiple VMware clouds to just managing multiple clouds (but this isn't reflected in the creation of VMware Hybrid Cloud Services).
Sanjay Poonan on EUC
Claiming that VMware will reduce TCO.
VMware acquires Desktone to and portal management layer - mainly targetting service providers offering DaaS
Software Defined Data Center
Vitualize everything, not just servers
Automate processes
Compatible Hybrid Cloud
Bring program ability and policy-based approach to all of IT
Align storage to apps requirements
Virtualize network for agility and speed
CEO AtoS Thierry Breton
AtoS have adopted the SDDC
Manage largest number of DCs in EU
Intend to eradicate internal emails
Focus is now moving from cost reduction to value add in as and data. Infrastructure should just be a given.
Big Data will form a key part of value add.
TB now a member of EU Cloud advisory group helping Europe to bring standards to cloud services.
vsphere 5.5
More of everything - cores, memory, storage
GA at the end of this week
Leader in delivery of cloud foundry
Emphasising apps moving to scale out with less dependency on infrastructure resilience.
Software Defined Storage
VSAN distributed shared storage across servers for resilience and performance, simple mgmt
New backup capability - vshphere data protection advanced 5.5 much more compression and quicker recovery
Flash cache now available. Virt so now included in 5.5 functionality

Introduction
Hotels are booked and a 7am flight out of Liverpool on Monday morning will take me there on a big orange plane. Looking forward to catching up on all that is VMware and their partners. This year I'll be looking to see how VMware intend to keep ahead of the game, deal with competition from Microsoft and OpenStack, and to more deeply understand Software Defined Data Centres and Networks. And there'll be the usual entertaining time finding the new and different solutions that third parties can bring to market, spotting who are likely to progress well in the future and who's no longer on the show floor.
First question is the slogan for the event: "Defy Convention". For me that would've worked 5 or 10 years ago, but VMware IS convention now, so we'll see how that one pans out during the conference.
I'll try and post reasonably regularly, but will also be tweeting along the way - follow me @NeilHAtDell to keep up to date.
Here's a first glimpse of the Fira Grand Via getting dressed up for the occasion (courtesy of VMWORLD Twitter account):
