Today was the first day to become a VCP on VMware vSphere 4. I wanted to become one of the first VCP’s on vSphere 4 within our company and tried to schedule the exam last week but due to voucher problems I didn’t succeed.
A colleague did manage to schedule and take the exam today and he became the first Centric VCP on vSphere 4. Congratulations Johan!
Just now, I was able to schedule the exam and just to put the pressure on, I expect to be a VCP on vSphere 4 coming Friday at 11:30 AM.
Last week Iomega announced a new NAS appliance called the Iomega StorCenter ix4-200d. It is based on EMC storage technologies and contains four SATA-300 drivebays. With a storage capacity of 2, 4 and 8 TB it is the ideal NAS appliance for small businesses, distributed offices and home office networks that require advanced data storage and protection features without the need for a dedicated IT staff.
By default the Iomega StorCenter ix4-200d is configured as a RAID 5 array but RAID 10 or JBOD is also possible. Free disk space can be monitored on the front LCD display.
The Iomega StorCenter ix4-200d is equipped with two gigabit ethernet ports which support link aggregation, network failover and subnetting. It also supports various protocols like iSCSI, NFS, DLNA, uPnP, Bonjour, SNMP, FTP, HTTP and Samba so it can be used with Mac-, Windows- or Linux hosts.
On the site www.vReference.com I came across a post announcing the “vSphere 4 reference card”. Wondering what this was I started reading the post.
It seems that Forbes Guthrie made a document containing hard limits for the vSphere 4 products. I found the list of items very wide and should come in handy when looking for limits of the vSphere 4 products.
The reference card is refreshed every now and then, so check out the site periodically. Or subscribe to the RSS feed of the site.
Hopefully this card can help you as future reference. I found it to be very helpful.
But today, Virtual Geek, Chad Sakac posted some pictures frm inside the Moscone Center where the VMworld crew is busy setting up all hardware for next weeks VMworld 2009.
There will be 3 datacenters which will support all the hands-on labs, e-mail stations, booths, etc. The largest datacenter consists of 16 racks, each containing 4 Cisco UCS blade chasis, with 8 blades each. This totals 512 blades(!) so computing power won’t be a problem.
Last weekend VMware launched a new course called ‘VMware View: Design Best Practices’. It’s a hands-on training course which explores the foundations of designing VMware View architectures and is meant for System architects, system administrators, IT managers, and individuals responsible for designing VMware View architectures.
the recommended design process;
the layered architecture design model and the reference framework for a View design;
design considerations to meet business needs;
VMware’s best practices for a View deployment.
Before you can attend you should have completed the VMware View: Install, Configure, Manage course or have equivalent experience with VMware View.
We’re now 1 week from the start of VMworld 2009 at the Moscone Center in San Fransisco. Unfortunately the VMGuru.nl-crew won’t attend but many of our fellow blogger will. According to our info, Gabrie van Zanten from Gabe’s Virtualworld and Eric Sloof from NTPro.nl will attend as will many others.
We will be monitoring all the VMworld 2009 news next week and will try to keep you informed as much as possible.
vSphere 4 HA may not work with certain IP addresses
Filtering through my e-mail after a short, one week, holiday I ran into an e-mail from one of my colleagues pointing me to VMware KB Article 1013013. This KB article describes one of the first patches for vCenter Server 4.
The problem is that High Availability in a vSphere 4 virtual environment may not work when a host failure occurs and the node failure detection algorithm fails when using certain IP addresses. VMware found out that this is due to the fact that all of the Service Console Port(s) or Management Network IP address(s) on an ESX host fall within the following range:
3.x.x.x – 9.x.x.x
26.x.x.x – 99.x.x.x
Note: You are not affected if one of Service Console Port(s) or Management Network IP address(s) on your ESX host falls outside of this range.
The problem can obviously be solved by changing (one of the) Service Console Port(s) or Management Network IP address(s) or install vCenter Server 4.0 Patch 1.
To get a new project funded is often hard work. You have to calculate how much it costs to build your virtual infrastructure and how fast you can save money so you can justify the investment. Even after you started the project and you are building the infrastructure you still have to keep an eye on your wallet. The same goes for virtualizing desktops. We calculate what it costs to create the virtual infrastructure for the virtual desktops.
But what do we do when the infrastructure is in place? We simply put the total cost for maintaining the infrastructure on the IT budget. Wouldn’t it be more sensible to let the ‘user’ pay for the resources he is using, like in the old days with shared computers/mainframes?
‘Virtualization increases risk of data loss?‘ Let it be very clear that this is not my opinion but a quote from an article published today by the ‘Automatiserings Gids’ (NL) in which it quotes James Lyne, security specialist at Sophos. Lyne made his statements during this podcast.
Normally I don’t respond to articles like this but this one is too ridiculous not to.
First of all, James Lyne is working for a Security/Antivirus manufacturer making these claims? Not very trustworthy. Do they have a new product to promote? The situation is identical to what Anne Jan wrote about on March 24th, ‘IT personnel lack communication skills‘.
Second of all, the claims made in the article do not show a very good understanding of reality.
I will try to translate and quote as precise and realistically as possible.
‘There is a bit of an unrecognized risk with the shift to virtualization that is compromising the security model that was traditionally in place. When you had a physical server, it was locked down in the data center and you controlled access to that resource using the operating system. You define access control lists that said that HR had access to this resource here or sales had access to these portions of data. With that physical system those access controls were very much a gate to getting access to the data because the only you could access it was over the network. With a virtual system we’re taking that physical hard drive and you’re putting it in a convenient file and that file, as it is the normal design of virtualization infrastructure, is placed on a SAN or some kind of shared storage, where people go to access data. And people are now not thinking about how they define controls over access to that file system. They’re not thinking about the fact that anyone who has access to the virtualization infrastructure now has raw access to the files that contain their most sensitive data.’
Usually everybody is on holiday during this period and because of that we lack new projects and great news. ‘Komkommertijd‘, as we call it in the Netherlands. Fortunately (for us) Duncan Epping, known from Yellow-Bricks, isn’t on holiday (yet) and he pointed me to some great new VMware whitepapers.
Today we’ve updated WordPress to its latest version. There was a serious bug in a previous version and we already had some nice people testing our security. So, from this spot, I’d like to thank them all for their work of probing our site about 5 to 10 times on a daily basis for securityholes, as well as testing our spamfilter for postings for 1.836 times.
Anyway, we’re up-to-date again and we hope to stay safe!
VMware announced yesterday that they are into a definitive agreement to acquire privately held SpringSource, a leader in enterprise and web application development andmanagement.
SpringSource is the innovator and driving force behind some of the most popular and fastest growing open source developer communities, application frameworks, runtimes, and management tools. In just five years, SpringSource has established a presence in a majority of the Global 2000 companies, and is rapidly delivering a new generation of commercial products and services. VMware plans to continue to support the principles that have made SpringSource solutions popular: the interoperability of SpringSource software with a wide variety of middleware software, and the open source model that is important to the developer community.
Together, VMware and SpringSource plan to further innovate and develop integrated Platform as a Service (PaaS) solutions that can be hosted at customer datacenters or at cloud service providers. These solutions will allow customers to rapidly build new enterprise and web applications and run and manage these applications in the same dynamic, scalable and cost-efficient vSphere-based internal or external clouds that can also host and manage their existing applications, providing an evolutionary path to the future. Forrester Research expects the emerging and rapidly growing PaaS market to expand to $15B by 2016. (Platform-As-A-Service Market Sizing, July 13, 2009)
