Storage VMotion now supported for iSCSI

Posted on June 26th, 2008 in SAN, esx3.5, iSCSI, stor vmotion, storage by Rich

Earlier this week the VMware VI Team Blog reported that as of ESX version 3.5 Update 1 Storage VMotion is now officially supported for iSCSI SANs. This means that administrators can reorganize virtual machines without down time in order to match any storage needs. The Storage VMotion and 10Gb Ethernet support for iSCSI SAN’s post explains:

“Although Storage VMotion is designed to work with any type of storage, it was initially supported only with Fibre Channel SANs. As of Update 1, Storage VMotion is supported with iSCSI SAN’s for moving virtual machine disk files in the following scenarios:

- From iSCSI SANs to other iSCSI SANs

- From iSCSI SANs to FibreChannel SANs

- From FibreChannel SANs to iSCSI SANs

In addition, we now support the use of 10Gb Ethernet for iSCSI in a VMware Infrastructure environment.”

In my experience Storage VMotion has worked great, but be careful with VMs that have higher I/O utilizations.

VI3.5 New Feature Summary

VI3.5 what's new summary

VMware VI3.5 is scheduled to be generally available by the end of 2007. Based on a public .pdf released by VMware, this post is my summary of the new features. I’m guessing this .pdf is really a .ppt presentation that VMware is delivering, but I have not attended this presentation myself.

The screen shot is from the document and shows the new features in the defined layers.

After some sales and marketing slides the document classifies the VI3 features today across 3 layers. These layers are then used to group the new features for the rest of the presentation.

The features are divided into 3 layers:

ESX 3.5 features announced!

Just when you thought the competition was catching up VMware does it again. Monday VMware announced the new features of the latest version of Virtual Infrastructure 3, which will be ESX 3.5 and VC 2.5. The new versions will be generally available later this year.

A description of the new features can be found in VMware’s news release

Here is the description of the new features from VMware’s announcement:

Virtualization platform enhancements help deliver new levels of performance, scalability and compatibility for running the most demanding workloads in virtual machines:

  • Expanded storage and networking choices such as support for SATA local storage, 10 Gig Ethernet, and Infiniband expand storage and networking choices for virtual infrastructure
  • Support for TCP Segment Offload and Jumbo frames reduce the CPU overhead associated with processing network I/O
  • Support for hardware nested page tables such as in processor assists for memory virtualization
  • Support for paravirtualized Linux guest operating systems enables higher levels of performance through virtualization-aware operating systems
  • Support for virtual machines with 64GB of RAM and physical machines with up to 128GB of memory

New virtual infrastructure capabilities help deliver increased infrastructure availability and resilience:

  • VMware Storage VMotion enables live migration of virtual machine disks from one data storage system to another with no disruption or downtime. VMware VMotion has become an indispensable tool for many infrastructure administrators to dynamically balance their server workloads and eliminate planned downtime for server maintenance. Storage VMotion extends VMotion to storage resources of a virtual machine, namely virtual disks. Using Storage VMotion, administrators can dynamically balance the storage workload and address performance bottlenecks by migrating virtual machine disks to the best available storage resource. Administrators can minimize service disruption previously incurred for upgrading storage arrays and free storage administrators to improve and manage the storage infrastructure without having to co-ordinate extensively with application and server owners.
  • VMware Update Manager automates patch and update management for VMware ESX Server hosts and virtual machines. Update Manager addresses one of the most significant pain points for every IT department: tracking patch levels and manually applying the latest security/bug fixes. Patching of offline virtual machines enforces higher levels of patch standards compliance than physical environments. Integration with VMware Distributed Resource Scheduler (DRS) enables zero-downtime VMware ESX Server host patching capabilities.

New virtual infrastructure management solutions help deliver increased automation for streamlined managed of IT environments.

  • VMware Distributed Power Management is an experimental feature that reduces power consumption in the data center through intelligent workload balancing. Working in conjunction with VMware DRS, Distributed Power Management is designed to automatically power off servers not currently needed in order to meet service levels, and automatically power on servers as demand for compute resources increases.
  • VMware Guided Consolidation, a feature of VMware VirtualCenter enables companies to get started with server consolidation in a step-by-step tutorial fashion. A wizard discovers physical servers, identifies consolidation candidates, converts them to virtual machines, and leveraging intelligently places them onto the best VMware ESX Server or VMware Server hosts. Guided Consolidation helps to make the consolidation process quick and easy for users with little knowledge of virtualization.

Thursday 9.13.07 Keynote - what I missed :(

Posted on September 15th, 2007 in appliance, availability, gen session, stor vmotion, vmware, vmworld by Rich

Unfortunately I slept late Thursday morning. Waking up at 7:30 am in Hayward, CA meant that there was no way short of a helicopter I was going to make it to San Francisco before 9. I’m pretty sure my company would not let me expense a helicopter so I decided to catch up on some email from the hotel until traffic burned off. I also had “Smash Head” from the party Weds night!

blog.scottlowe.org has some great notes on this session. Here’s my thoughts on what I missed.
