Today EMC’s Chad Sakac blogged about a significant update to Oracle’s support policy for VMware ESX environments – Oracle no longer explicitly excludes Oracle RAC from being virtualized. It should also be noted that Oracle’s support is limited to “issues that either are known to occur on the native OS, or can be demonstrated not to be as a result of running on VMware.” In other words, if it’s not a known bug, customers may be asked to reproduce problems on the bare metal.
Like Chad, this is an issue I have blogged about repeatedly over the last couple of (Read more...)
Today the Wall Street Journal reported “VMware in Talks to Buy Novell Unit.” The rumor likely comes as no surprise to those who have followed the recent VMware/Novell OEM agreement. The agreement resulted in VMware including a SUSE Linux Enterprise Server (SLES) subscription with vSphere licenses. VMware and Novell first started talking about an extended partnership in June. At the time, VMware noted that it would include SUSE Linux with its vSphere hypervisor as well as train its support organization to offer SUSE Linux support. The fact that VMware was making an investment in its support organization (Read more...)
Once upon a time an IT user named Goldie Locks tried to access her company’s applications…
I’ll spare you the rest of the analogy. Some devices are too big, others too small, and some are just right. Of course, “just right” often depends on the application being consumed. I talk a lot with clients about user-centric computing and the fact that many in today’s mobile workforce do not want to be tethered to a single physical device. “Give me my apps on my terms” may represent a Utopian user viewpoint, but it’s still one that’s a priority for many IT (Read more...)
I have three sessions at this year’s VMworld North America conference and thought I would post them here in the event you’re interested in attending one of them. Each session will run two times, and the session descriptions, times, and locations are listed below. I hope to see you at the conference. The in-depth discussions I have with fellow attendees has always been one of my favorite parts of the conference.
Server-Hosted Virtual Desktops: What the Vendors Aren’t Telling You (DV8044)
Many organizations are beginning to implement or plan server-hosted virtual desktop solutions. Vendor platform assessments in the emerging client (Read more...)
Today I was working with a client on their next generation data center architecture. They are building a highly virtualized data center with the goal of offering cloud IaaS to other departments within the organization. While talking about VM templates we discussed a favorite topic of mine – virtual hard disk structure.
For several years, I have recommended to clients that they use at least two virtual hard disk files per VM. One virtual disk file is used for the OS and application files, and a second virtual hard disk is used for paging, swap, and temp files. Alternatively, a (Read more...)
On Monday VMware announced the release of vSphere 4.1. VMware published a document describing the new features, and I also recommend checking out VMware CTO Steve Herrod’s post as well as Eric Siebert’s great vSphere 4.1 links post. I was planning to link to several good perspectives on the vSphere 4.1 release, but Siebert’s “links” post has them all and I suggest you take a look.
Granted, I’m a little late to the vSphere 4.1 discussion, but I thought I’d add my two cents nonetheless.
First, the release doesn’t feel like a ‘”.1” update. The feature additions and (Read more...)
On Tuesday at the Microsoft Worldwide Partner Conference, Microsoft announced the availability of the Windows Azure Platform Appliance. Since Azure was first announced, I had been advising clients that an on-premise Azure offering was only a matter of time. With Tuesday’s announcement, Microsoft took a first step toward an Azure platform that is capable of driving internal cloud service delivery.
To be clear, Azure isn’t available to anyone who wants it. Instead, only very large enterprises (i.e., eBay) and providers (e.g., SugarCRM, GXS, and Siemens PLM Software) have access to the “appliance” at this time. The Azure appliance isn’t (Read more...)
I recently confirmed all of the speakers for the server virtualization track at Catalyst North America, and am very excited about the participants. The conference runs the week of July 26th, with workshops on Monday and Tuesday and conference breakout sessions from Wednesday to Friday. Wednesday we’ll have a full day of cloud coverage, and I’m chairing the track “Virtualized Data Centers: Servers, Storage, Networks, and Security,” which runs all day on Thursday. The conference concludes on Friday with an outstanding client virtualization track. Speakers in that track include: Harry Labana – CTO – Citrix, Scott Davis – CTO (Read more...)
As a follow-up to my previous post on Synergy 2010, I wanted to take a moment to reflect on the cloud and server virtualization announcements. Citrix made the following product announcements at the conference:
- Citrix Unveils Open, Extensible, Turnkey Cloud Solutions
- Citrix Unveils Next XenServer Release as Reports Show Server Virtualization Market Share Growth
- NetScaler Delivers Industry’s First Virtualized Delivery Infrastructure for Microsoft 2010 Apps
- Citrix NetScaler Pay-as-You-Grow “Burst Packs” Make Networking More Elastic
Citrix announced the release of XenServer 5.6, which includes several significant feature improvements:
- Hypervisor-level role-based access controls (RBACs)
- Dynamic memory support
- Dynamic workload balancing
- Automated site (Read more...)
I submitted four proposals for this year’s VMworld conference and learned that three of them are up for voting. I think the fourth is in a VMworld black hole. I wasn’t notified that it was accepted and it’s not up for voting either. I guess I’ll know soon enough… If you’re curious, that proposed session was titled “Private Cloud Security: Vendor Secrets and Hypervisor Competitive Differences.”
Anyway, if you’re not tired of my jokes and would like to see more of me at VMworld North America or VMworld Europe, you can vote for my sessions online. Note that you will need to register for a VMworld.com account if you don’t have one already.
Here are the descriptions of my sessions that are up for voting.
Server-hosted Virtual Desktops: What the Vendors Aren’t Telling You
Many organizations are beginning to implement or plan server-hosted virtual desktop solutions. Vendor platform assessments in the emerging client virtualization market are often difficult due to a lack of defined acceptable standards. In this session, Burton senior analyst Chris Wolf and analyst Simon Bramfitt share Burton Group’s benchmark for evaluating server-hosted virtual desktop solutions, including criteria for evaluating a solution’s deployment, management, performance, integration, and user experience capabilities. The session concludes with a breakdown and scorecards of popular vendor solutions, including the current Citrix and VMware products.
Simon Bramfitt and I will repeat and expand on our session from Citrix Synergy and will include analysis of Microsoft VDI and Quest vWorkspace in addition to VMware View and Citrix XenDesktop. If time permits we will assess more products too. You can vote for this session here. If you search for “Simon Bramfitt” you will find the session. I’m note sure why my name isn’t listed, but assume the voting system only accommodates one speaker.
Extreme Makeover: Data Protection Edition
Applying legacy data protection architectures to today’s heavily virtualized modern data center comes at a significant price in terms of both performance and consolidation density. We are at a time where organizations should reevaluate existing data protection practices and leverage new technologies to improve data recovery and lessen or eliminate the performance tax posed by many existing data protection architectures. This session breaks down modern VM data protection solutions, including VMware’s vStorage API for Data Protection, array-level snapshots and replication, and third party enterprise backup software solutions. Attendees will be exposed to common data protection pitfalls as well as successful blueprints for modern VMware data protection architectures. Chris Wolf has been architecting data protection solutions for enterprise virtualization environments since 2002 and includes an abundance of lessons learned and best practices drawn from real world implementations in this session.

Cloud Futures: The Infrastructure Authority
To realize the potential of private cloud, infrastructure must be capable of not just dynamically provisioning and optimizing systems, but also not violating any security, regulatory, or organizational policy constraints in the process. In many enterprise environments, dynamic IT consists of several disjointed solutions and oftentimes blind faith that policy, security, or regulatory constraints will not be broken. The bottom line – someone has to be in charge. The infrastructure authority (IA) is the future nerve center of cloud infrastructure as a service (IaaS) operations. Among the many roles the IA possesses are:
- Provides a central metadata store
- Leverages common data models to request or offer services
- Maintains physical, virtual, and policy dependency maps
- Ensures security and regulatory compliance
- Ensures that service level requirements are met
- Stores and enforces organizational policy
- Ensures accurate capacity forecasts
- Integrates with third party management and orchestration tools to authorize IT operations such as provisioning or relocation before they proceed
Typical questions answered by the IA include:
- Are security zoning rules checked before live migrating a VM?
- Do any policy restrictions prevent VMs from migrating to different data centers or to public cloud infrastructure?
This session takes a practical look at the emerging role of the IA, and details how existing management frameworks such as VMware vCenter and industry standards such as OVF can be used in this capacity moving forward.
