Now that we have officially launched Virtual SAN, its time for everyone to get up to speed with the some of the latest and greatest changes with regards to the new design and sizing considerations guidance for Virtual SAN.
Yesterday, we announced the official release time frame for the general availability of the product the week of March 10th as well as the items listed below:
3 to 32 node cluster support
Maximum support of 3200 Virtual Machines
2 Million IOPS performance capability
4.4 Petabytes of Storage Capacity
Along with those changes and updates there are also some significant changes in the recommendation for the sizing of the flash layer for Virtual SAN. I highly recommend reviewing the white paper as the new sizing guidelines can have an impact on the overall investment and performance of the flash layer for Virtual SAN. The new design and sizing guide can be found and downloaded from the VMware Virtual SAN product page or directly from the link provided below:
VMware is excited to collaborate with Fusion-io, a leader in flash solutions with deployments by more than 6,000 customers, to provide customers a range of 15 enterprise-class PCI-E SSDs certified for Virtual SAN™ (see the VSAN Compatibility Guide). Virtual SAN™ leverages the speed and power of server-side flash to deliver a high-performance cache in front of direct-attached disks to provide scalable and cost-effective shared storage solutions.
SanDisk is actively supporting VMware in our Virtual SAN™ launch, providing high-performing, high-endurance flash drives that enable enterprise-class scalability while minimizing IO storage latency for read and write operations.
Many of you have now kicked the tires with vSphere 5.5 either in your home lab or on some servers at work and you’re anxious to get all the new goodies running in your production environment. Perhaps some of you early adopters are already running in full production, but we’re guessing many of you are just contemplating your major upgrade now.
VMware’s Tech Support staff tend to see a surge during the month of March in number of calls to support. But guess what? Many of the issues we’re anticipating are already resolved, and we’ve been busy compiling and documenting solutions to common problems that you can handle yourself.
Those of you installing or upgrading your vSphere hosts, and vCenter Server instances to version 5.5 will find the following KB articles and Support Insider posts of great interest.
I’ve been involved recently in a couple situations in which the ‘perferHT’ advanced setting has been implemented, but for the wrong reasons. I want to re-clarify how and when it should be used. As with many advanced settings, it can be helpful or hurtful.
“PerferHT exposes Hyper-Threading to the guest operating system” – False!
A great question crossed my desk today from a customer. “Can a VI Admin who has root access to ESXi “abuse” their privileges and “peek” inside the guests of VM’s hosted on the server?”
The short answer? If your ESXi admin has root or full administrator privileges, they can do anything. Nobody should be surprised by this! HOWEVER, you can mitigate, limit and monitor what is being done.
But first, let’s quickly review what is meant by “peek inside the guest”. In the human world, Continue reading →
The Virtual SAN team has been running a public beta program for the past six months with more than 12,000 people registering online. We have received a lot of feedback during that period and wanted to share with you the experience of a few of them.
This is the first post of a series of customers talking about their experience with Virtual SAN.
VMware vSphere Data Protection (VDP) Advanced is able to perform true application-consistent backup and recovery of tier-1 applications – specifically, Microsoft SQL Server, Exchange, and SharePoint. This functionality is enabled by the VDP Advanced application agents for these applications. With these agents, administrators can back up and restore individual databases, enable multiple backup streams, truncate database logs, and restore individual Exchange mailboxes. Up until now, these agents were only supported for applications running in virtual machines. I am happy to report that it is now possible to offer the same level of data protection for these applications running on PHYSICAL servers! I repeat – VDP Advanced can now backup and restore SQL Server, Exchange, and SharePoint running on physical servers. Keep reading for more details…
