Building a next-generation on-premises infrastructure

As much as the cloud is having a significant impact on how IT is deployed, on-premises infrastructure is here to stay. Over the last few years the industry has made huge progress with regard to Storage Performance, Systems Availability and Operational Simplicity – let’s take a look at some of our solutions that enable you to take advantage of these and build a next-generation infrastructure: Hyper-Converged Infrastructure We have several options available that: Combine compute and storage into a single scale-out solution Enable simplified provisioning, management and upgrading HCI solutions are taking over from separate compute and storage as they promise to deliver the simplicity of the cloud. Continuous Availability We have several options available that: Automate disaster recovery fail-over Achieve zero downtime even Continue reading

VMworld 2015 key announcements summary

Now that the dust has settled I thought it would be useful to review the key announcements: Virtual SAN 6.1, key enhancements include support for: Stretched Clustering with Zero RPO 2 node ROBO configurations vSphere Replication with a 5 minute RPO (exclusive to Virtual SAN) Multi-Processor Fault Tolerance (SMP-FT) Intel NVMe and Diablo Ultra Dimm The Stretched Clustering feature will require the Advanced licence, which also includes support for All-Flash. The beta of the next release was also announced – this will include some hugely important enhancements: Disk Group based de-duplication (All-Flash only) Erasure coding (RAID 5 or RAID 6) End-to-end checksums with a background scrubber I have written quite a bit about Virtual SAN, it always felt to me that it was very early generation Continue reading

VMware changes EVO:RAIL licensing but still gets it all wrong

My view on EVO:RAIL has always been that it is a nice piece of technology, but it is way too expensive with a deeply flawed licensing model (more thoughts at VMware EVO:RAIL or VSAN – which makes the most sense?). It has just been “improved” because you can now use existing vSphere licenses which will dramatically reduce the cost of the appliance (more details here). Even though VMware had a great chance to really make things so much better they have wasted the opportunity – amazingly they are still forcing you to use Enterprise Plus whereas Essentials Plus would be more appropriate in most cases. It is also not clear if the vSphere licences can be moved, or if Virtual SAN and Log Insight Continue reading

Exploring Long-Distance vMotion in more detail

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 Continue reading

How can VMware provide more value to its customers in 2015?

Competition is essential as it ensures that vendors focus on the value proposition of their products, the good news for the hypervisor market is that it is now very competitive with Hyper-V, KVM and XenServer challenging the market leader – vSphere. As VMware is put under pressure from its competitors it tends to respond in one of two ways: Increase the technology lead between its products and the competitors through innovation Increase the value of its products by bringing high-end features down to lower editions An example of the latter happened when Hyper-V 3.0 was released and VMware responded by adding features like vMotion and Storage vMotion to vSphere Standard. So what can VMware do to provide more value to Continue reading
