Improved webclient. Unfortunately it's still not in HTML5.
So it’s finally here!
The long-awaited release of vSphere 6.0, has been released, and will ready for download medio March we’ve been told. I’ve done a small write-up of some of the new features in this release.
Release cycles
As seen at VMworld, where many customers thought that VMware would release vSphere 6.0, VMware has adopted a strategy of longer release cycles of the core component vSphere. So instead of a yearly release we are most likely to see roughly 18 months release cycles instead. This is because the hypervisor needs to be stable all the time, and not something you’d need to upgrade all the time. On the other hand products like vRealize Operations or vRealize Automation Center will see shorter release cycles. I’m really liking this approach, as the hypervisor really is in the center of your data center core, and as such we need the absolute most stable product here.
Multi-processor Fault Tolerance
We’ve seen multiprocessor Fault Tolerance demoed at a few VMworlds so far, but now finally it’s here. with vSphere 6.0 you can now have Fault tolerance on VM’s with up to 4 vCPU’s. This finally opens up for the useful Fault Tolerance VM’s. I haven’t seen many critical VM’s with only 1 vCPU, even vCenter Server needs more than 1, so the use cases for the old Fault Tolerance were few and far apart.
A lot of older applications, haven’t been built with High Availability in mind and for this FT comes into play, and with the new 4 vCPU limit a lot more of older applications can be protected by FT as well. I’m guessing a lot of costumers will use this feature in their data centers. However the Bandwidth requirements for this will be quite steep, so cross data center FT might not be feasible just yet :). As with the old FT this won’t save you if your application corrupts, then both instances will be corrupt. For this you really need applications that were built for High Availability in mind.
Inter vCenter vMotion
This I think is one of the biggest new features of vSphere 6.0. The ability to vMotion between 2 vCenters is one thing a lot of people have been looking for, for a looong time. Moving VM’s without downtime to a new vCenter with newer vSphere, wasnt that easy if you deployed distributed switches. But now that really should be a thing of the past. A whole new set of design architectures should be set up now because of this feature.
Long distance vMotion
Another really nice new feature is long distance vMotion, where before you were limited to 5ms latency or 10ms in Enterprise+, you can now vMotion across links with up to 100ms of latency. For us Europeans that means we should vMotion vm’s across borders to neighboring countries or at last across the country. This opens up quite a few new scenarios for highly available infrastructure. In Denmark fx. we could vMotion between Seeland and Jutland, which would solve some of the Power issues we have :).
Web client
The last thing I will write about is the client. The new Webclient is much improved over the previous ones, and both looks and feels more like the C# client, which still is available in vSphere 6.0. Unfortunately its still not in HTML5, which would have been preferred, so the webclient could work on OS’s

VMware vSphere 6.0 features "brain-dump"
Originally posted at vcdx133.com.
The amazing VMware vSphere 6.0 has just been announced and will be released in March 2015! Michael Webster wrote a great article about the significance of vSphere 6.0 that is worth reading. This a “brain-dump” of the impressive new features and improvements:
- Enhancement of vCenter Server architecture – SSO has evolved to the multi-service Platform Services Controller (SSO, Licencing, Certificate Authority, Certificate Store, Service Registration).
- vCenter Server Appliance – supports large (1000 hosts, 10,000 VMs) environments and Linked Mode
- Enhanced Linked Mode for vCenter – Microsoft ADAM has been replaced with a VMware “native Replication Technology” where vCSA is supported and Policies and Tags are also replicated.
- IP version 6 – Static IPv6, DHCPv6 with FQDN for 100% management of hosts and iSCSI, NFS, VMFS IPv6 support.
- Availability – Improvements to the Watchdog Remediation features of vCenter (SSO, vCenter, vCenter DB).
- Content Library – an Administrator’s multi-vCenter central repository for all VM Templates, ISO images, scripts and vApps.
- vSphere Client – is only used for direct connection to the ESXi host and for connecting to vSphere Update Manager, all other tasks must be performed with the vSphere Web Client.
- Enhanced vMotion – Cross vCenter vMotion supported and Long-Distance vMotion of up to 100ms RTT.
- vSphere Fault Tolerance supports 4 vCPUs and 64 GB RAM – with VADP support and any vDisk provisioning on different datastores.
- Increased Scalability – 64 Nodes per Cluster (incl. VSAN), 8,000 VMs per Cluster, 480 Logical CPUs per Host, 1,024 VMs per Host, 12TB RAM per Host.
- Virtual Data Center and Policy Based Management – Automates VM provisioning based on capacity and capability. Intelligently place VMs based upon policy. Monitor VM policy adherence with automated remediation. Automate initial VM placement without writing complex policies. Ongoing operational efficiencies via policy-based remediation throughout VM lifecycle.
- NFS Client version 4.1 with Kerberos – NFS benefits from Session Trunking and Multipathing, improved Security and improved Locking, Error Recovery and NFS Protocol efficiencies.
- Virtual SAN – All Flash datastore with SSD persistence. 2x more IOPS with VSAN Hybrid (up to 40K IOPS/host). 4x more IOPS with VSAN All-Flash (up to 100K IOPS/host). 64 Nodes per Cluster. 150 VMs/host (Hybrid), 200 VMs/host (All-Flash). VSAN Snapshots and Clones. H/W-based checksum and encryption support. Blade architectures supported (DAS JBOD). Rack awareness (tolerate rack failures). Flashing LEDs to detect failed disks.
- Virtual Volumes (VVols) with Storage Policy-Based Management (SPBM) – removes the need for management of LUNs and NFS volumes via enhanced VASA APIs. A single VVol is the equivalent of a VMDK file. Extends SDS control plane to monolithic storage.
- Storage I/O Control – Per VM reservations.
- Network I/O Control – Per VM and Distributed Switch bandwidth reservations.
- Support for FreeBSD 10.0, Asianux 4 SP3.
- Security Enhancements – Increased Flexibility of Lockdown mode, Added Smart Card Authentication to DCUI, Improved password and account management, Enhanced Auditability of ESXi admin actions, Added full certificate lifecycle management, Added certificate based guest authentication.
NOTE: This is based upon the information and features provided in the RC version of the vSphere 6.0 (Beta 2). There may be some differences between the features of the RC and GA versions.

Hopefully Long-Distance vMotion is only going to get better.
One of the major new features of vSphere 6 is the ability to vMotion over very long distances. With previous releases of vSphere the maximum network Round Trip Time (RTT) was 10 ms which equates to a distance of almost 400 miles. With Long-Distance vMotion the RTT has been increased to a whopping 100 ms which increases the distance to 4,000 miles – far enough to move a VM from London to New York.
Of course you do still require a L2 stretched network (L2 adjacency) which is where technologies like vSphere NSX come in, but what about the storage?
vSphere 5.1 introduced Enhanced vMotion which combined vMotion and Storage vMotion into a single operation so that shared storage was no longer required – essentially Long-Distance vMotion moves all of the storage for a given VM along with its memory.
This does not sound ideal as you would need to move an awful lot of data between London and New York – it is one thing to move a few GBs of RAM, but 100s of GBs of disk per VM is another matter. The answer to the problem is to combine Long-Distance vMotion with asynchronous storage array or vSphere replication.
For vSphere Replication this should be relatively straight forward as it is integrated into the hypervisor and it works at the VM level, storage array replication will be much more of a challenge as typically it replicates an entire datastore containing many VMs.
This is where Virtual Volumes comes in to play as they should allow replication to be controlled at the VM level. Long-Distance vMotion would need to synchronise the replication and switch the active site – sounds like a complex task, but it would bring tremendous advantages and make Disaster Avoidance available over almost any distance.
I am quite sure that this is something that VMware is currently working on with the likes of EMC and NetApp – so watch this space as hopefully Long-Distance vMotion is only going to get better.

This server class product is very stable, but expensive.
Valuable Features:
This server class product is very stable, I have been using it for more than 7 years, previous versions were named different with less bugs. No downtime.
Room for Improvement:
Pricing can be considered as measure block small and mid range companies. Company needs to think in this direction as well.
Disclosure: I am a real user, and this review is based on my own experience and opinions.
@Radu and Carlos,
If you are installing Vsphere 5.1, it comes with a web interface, just be sure to install it, the software runs on port 9443, it is called VMware Vsphere Web Client. Most of the time, people select the default installation items instead of installing this aspect of the program.

Allows us to create or clone a virtual environment in a short period of time and has good stability and support
Pros and Cons
- "The ability to create or clone a virtual environment in a short period of time for testing is most valuable."
- "An improvement could be in terms of keeping up with the upgrades. The upgrades could be set in an automated way so that the newer features don't require you to manually update, or you get an option to update automatically. This would be a useful enhancement."
What is our primary use case?
We use it to create virtual machines and things like that.
What is most valuable?
The ability to create or clone a virtual environment in a short period of time for testing is most valuable.
What needs improvement?
The enhancements that come out from time to time usually surpass what we need. We tend to upgrade because we do not want to be behind, but our needs don't continually grow. We are not very fast in terms of appetite for new things. However, we do appreciate that there is a continuous improvement, and for us, it is just a matter of being able to spin up a new environment quickly.
An improvement could be in terms of keeping up with the upgrades. The upgrades could be set in an automated way so that the newer features don't require you to manually update, or you get an option to update automatically. This would be a useful enhancement.
For how long have I used the solution?
I have been using this solution for three years.
What do I think about the stability of the solution?
It is very stable.
How are customer service and technical support?

A straightforward setup with good documentation and excellent stability
Pros and Cons
- "The documentation is very good."
- "Sometimes you can't find items and you need to log onto different physical servers to do technical tasks. I don't fully understand why this is the case."
What is our primary use case?
The solution is primarily used to house VMs, virtual machines.
How has it helped my organization?
Virtualization changes radically the IT landscape. Rare are our customers who have not implemented it. vSphere is #1 in hypervisors and offers the flexibility and the fastness our customers need.
What is most valuable?
VM models is a great feature. It allows to create VMs very fast and already patched with the different configurations that the are needed.
The ease to move a VM from a host to another or even to another storage/DC is very convenient. That all this can be done while users work on the VMs is awsome.
What needs improvement?
The graphical vSphere vCenter interface is now in HTML. I'm not very found of it. Sometimes you can't find items and you need to log in to the different hosts.
Some work has to be done with this admin console.
For how long have I used the solution?
I have many years (lost the count...) of experience with this solution, beginning with version 4.0, then 5.0, 5.5, 6.7 and finally 7.0 and use it daily.
What do I think about the stability of the solution?
The stability has been very, very good. I didn't have any crashes. There aren't bugs or glitches. I find it to be a very, very strong architecture.
What do I think about the scalability of the solution?
In terms of scalability, I haven't really had the opportunity to address this as my customers are not very big companies and we have relatively small data centers.
How are customer service and technical support?
I've never had to call VMware. You basically can find everything on the web. VMware's website is very good and there is a lot of information everywhere about vSphere on the web with real experts of the product.
Which solution did I use previously and why did I switch?
No
How was the initial setup?
The setup is straightforward, only a few questions to answer, and you have your hypervisor ready !
What about the implementation team?
Always in house.
What's my experience with pricing, setup cost, and licensing?
The cost of the solution is relatively low. VMware proposes the Essentials kits which are very affordable for SMB companies.
Which other solutions did I evaluate?
I didn't really evaluate any other solutions. I haven't even really looked at Hyper-V, although my clients sometimes ask about it.
What other advice do I have?
We are implementors and our customers don't sometime have any dedicated IT guy. But, as vSphere works well once implemented, there's relativally less to do.
Which deployment model are you using for this solution?
On-premises

We can see that C# client is fading away(I would say its gone).. Some features like edit virtual machine with vHW 10 cannot be done with C client.. NSX Management cannot be done.. Same with products like RPVM.. and you cannot do LACP configs with C client.. And I am with you - webclient is much improved.. But need more :)
