TV Guide for March 30

March 30th, 2010 at 11:01 AM  1 Comment

This is the introduction post to the TechVirtuoso Guide, what we hope will become a daily breakdown of important IT tidbits from the previous day, and what we expect to happen that day.

Yet again, someone has come forward with another rumor that a CDMA iPhone is coming this summer. This time, it comes from the Wall Street Journal. The new iPhone would work on Verizon Wireless, as well as Sprint Nextel in the United States and a handful of carriers in other countries including South Korea and Japan. The current iPhone is designed to work on the vast majority of carriers world-wide, including AT&T and T-Mobile in the US, using a signaling technology called GSM.

It would seem that SSL isn’t as secure as once thought. The problem isn’t the encryption, but the certificate providers. Ars has a breakdown of how governments are working with the CAs to “subvert the entire system to allow them to spy on anyone they wish to keep tabs on.”

Apple has released a major update to OS X 10.6 “Snow Leopard” — fixes in version 10.6.3 include enhancements to USB, OpenGL, DNS, QuickTime X, AirPort, iCal, Mail, MobileMe, Time Machine, and numerous other areas of the operating system. Choose Software Update from the Apple menu to check for the latest Apple software via the Internet, including this update.

Future versions of the Ubuntu Linux operating system will change the way units are measured in the operating system and enforced throughout applications used in the OS. Starting in Ubuntu 10.10, coming this October, SI prefixes (base-10) will denote 1 kB as 1000 bytes, 1 MB as 1000 kB, 1 GB as 1000 MB, and so on. This is similar to the way OS X started measuring data in Snow Leopard. Neowin has a full breakdown of the measuring guidelines.

You will soon be able to jailbreak an iPhone over the air, instead of having it tethered to a computer. Your move Apple.

Need help running Linux as a guest OS in Microsoft Hyper-V? Sounds strange, but Microsoft has released a best practices guide to do just that. Download it off their website. Don’t blame us if you create a black hole in your datacenter though. In related news, has a great article on anti-virus exemptions in Hyper-V. Proper configuration of your antivirus can prevent performance issues, but also keep your VMs from being eaten alive by an aggressive scanning engine.

Great overview of VMWare vs Microsoft server virtualization options

January 16th, 2010 at 1:40 PM  1 Comment

Up until this last year, the virtualization options available from Microsoft lagged woefully behind VMWare. This is led people like me to really ignore Microsoft’s virtual offerings. However, Redmond is quickly playing catchup with the release of Windows Server 2008 R2 and the upgrades to the integrated Hyper-V virtualization options, as well as other platforms such as MED-V, Virtual PC and App-V. This is causing a lot of other administrators to take a second look.

Over at the blog Clustering For Mere Mortals, David Bermingham has a great write up comparing the features, pros and cons of  the latest version of Hyper-V vs VMWare vSphere (previously ESX)

How do I recover my virtual machines in the event of a complete site loss? The good news is that virtualization makes this process a whole lot easier since a virtual machine is just a file that can be picked up and moved to another server. While up to this point VMware and Microsoft are pretty similar in their availability features and functionality, but here is where Microsoft really shines. VMware offers Site Recovery Manager which is a fine product, but is limited in support to only SRM-certified array-based replication solutions. Also, the failover and failback process is not trivial and can take the better part of a day to do a complete round trip from the DR site back to the primary data center. It does have some nice features like DR testing, but in my experience with Microsoft’s solution for disaster recovery they have a much better solution when it comes to disaster recovery.

Head on over to his site to get the full rundown.

HP_logoHP is announcing  today HP Converged Infastructure, a group of new and revitalized HP products that will revolutionize the way IT looks at their datacenter solutions.  This virtualized collection of network, storage and shared servers can be virtualy allocated to meet the growing needs of the business faster and easier than ever before.

TechVirtuoso was able to speak to Lee Johns on a conference call earlier today about the Storage Works products that would fall under the HP Virtual Resource Pools category.  The three products that the call focused on were the HP StorageWorks X9000 Network Storage System FamilyHP StorageWorks SAN Virtualization Services Platform v3.0 andHP StorageWorks Cluster Extension EVA software with Microsoft Hyper-V Live Migration.

The HP StorageWorks X9000 family leverages technology from the aquisition of IBRIX and can scale up to 16 PetaBytes.  HP is planning on an inital release of three revisions from the X9000 family available for shipment November 16th for as low as $1.50 a GB.  The X9000 family includes the X9300 Network Storage Gateway; a 2 unit rack mount solution that brings scale out services to HP or 3rd Party arrays or sans, the X9320 Network Storage System; a highly available scale-out storage solution and the X9720 Network Storage System which will serve and store hundreds of terabytes or petabytes of file based data.  The X9720 will ship on January 4th.

The HP StorageWorks SAN Virtualization Services Platform v3.0 (or just SVSP v3) allows IT to simplify management of HP and 3rd party SAN devices.  V3 brings some major improvements to the platform including simplifing the creation of LUNS.  SVSP V3 is currently available starting at $31,032 for an entry 1 terabyte configuration which includes the hardware and the SVSP VM license.

The HP StorageWorks Cluster Extension EVA software with Microsoft Hyper-V Live Migration is a new product which will give a high availability solution to Hyper-V users currently utilizing multiple EVA units.  It will allow for auto-failover of  application services as well as read and write enabling of remotely mirrored mir-range storage over your MAN.  The HP StorageWorks Cluster Extension EVA software with Microsoft Hyper-V Live Migration will be available on November 25th for a U.S. list price of $5280.

Note:  Some links may not work until HP officially announces these products.  They are scheduled to release the announcement at 9:00AM 11/4/2009.
