Virtualized Geek The more I think about it the strategy of VMware joining OpenStack is starting to make more and more sense.  I wrote an earlier piece on how vCloud Director vs. OpenStack wasn’t the debate.  Similar I don’t believe VMware and OpenStack compete at even the datacenter layer or Cloud layer for that matter.  An argument could be made that before VMware and EMC spun off Pivotal that OpenStack and VMware were direct competitors but since the spinoff I’m thinking VMware really does want OpenStack to succeed. My basic argument is OpenStack is doing for VMware what open source is designed to do at it’s core.  Which is to give contributors and users a jump start on the product and services based on the core distribution.  The “traditional” players use of OpenStack has been an obvious and I’d argue intended use case.  Rackspace, Dell and HP are all Cloud providers that were looking for a Cloud OS.  While players like IBM may or may not use the code to pro

Dell VRTX- First Impressions
whiteboardninja

On Tuesday, 6/4/13, Dell unveiled its new PowerEdge VRTX converged system during the opening keynote at the 2013 Dell Enterprise Forum in San Jose, CA. The VRTX comes in a Tower or Rack mounted form factor covering 5RU. Inside, you will find slots for 4 of Dell’s M520 or M620 blades, the same servers found in their M1000 Blade Chassis. An onboard CMC provides iDRAC and remote management for the chassis. Each blade maps up to 4 GigE ports on an integrated switch, and there are 8 additional PCIe slots that can be mapped directly to the blades for more IO and accessory options such graphics adapters. In addition to the shared PCIe slots, there is a shared PERC controller (SPERC) that controls access to up to 25 integrated 2.5 inch or 12 3.5 inch drives. Both Howard Marks and Kevin Houston have done great posts on the details and specifications of the VRTX. Being a vSphere-centric kind of guy, my first thoughts about the VRTX were that it could replace the commonly deployed “3-

How Many Tools Does a Man Have to Have Before You Call Him a Man?
Shmuel Kliger

Last week VMWare announced adding yet another tool, Log Insight, to the collection of tools called vCOPS. In the last two decades IT management is in a race to nowhere. A race to discover more, collect more and present more. More reports, more graphs, more views, more alerts. If there is an IT asset out there, there is a tool to discover it. If there is a metric that can be collected, there is a tool to monitor, graph it and alert on an exception. How many management tools do you have in your environment? Which one do you use when? How many different reports/views/alerts are you looking at each day? How much time do you spend investigating these reports? Are you in control? Do you sleep better? IT environments are complex. Managing these environments can be challenging. Many different moving parts with very complex interactions make it very difficult to effectively track, monitor and control the environments. For years, trying to address the broad range of pain points, we kept throwing

Tech Round-up for 6/18/13
The Gotham Blog

Here are some of the technology stories that caught our eye today: BlackBerry issued a security advisory to customers yesterday concerning a bug in the Z10 smartphone that may allow unauthorized access to the device over Wi-Fi. According to security researchers, the increase in SSL internet traffic will negatively impact firewall performance, as firewalls have to decrypt and re-encrypt data with more complex encryption. Google is testing a new way to provide Internet access to isolated, poor, and underserved areas by using high-altitude balloons to beam data to antennas on the ground. Adobe has released their Creative Cloud to the general public, one month after announcing that the Creative Suite software would now be offered via the cloud.

What’s With All The Linux, I Thought We Were Talking About The Cloud
Perspectives on Cybersecurity from Learning Tree International

As Larry Ellison has famously observed, people use “cloud computing” to mean everything, and therefore nothing. In with the buzzwords in, out with the meaning. Take anything that involves two computers and a network connection, and someone is going to call it cloud computing. Or if you are going to use virtualization: some people rationalize this as “Cloud computing must be based on virtualization technology, therefore our rack of blades running vSphere is a cloud.” Yes, and my stove, just like a true cloud data center, runs on electricity. But I don’t call it a cloud platform. In Learning Tree’s Cloud Security Essentials course we take a narrower view. That course is aimed at people considering the use of what I think even Larry Ellison would call major cloud services — Amazon Web Services, Google Cloud, Microsoft Windows Azure, and so on. The security technology is precisely the same as in any other computing environment, the difference is in who h

Flash Memory Summit 2013 Session: Differentiate or Die – Marketing Flash-Based Storage Systems
marketing storage

I am delighted to be chairing what may be the first ever marketing-oriented session at the annual Flash Memory Summit in August 2013. A lively panel of experts, editors, and analysts will be discussing product differentiation in a growth market in a session called: Differentiate or Die – Marketing Flash-Based Storage Systems on Wednesday, August 14, 9:50-10:50 am. This is an Open Session so you can register for free up until 8/11/13. Product differentiation is a strategically important topic for businesses who develop products using using flash memory. It’s important because there are many ways to position such products, competition is fierce, and the process of positioning (or repositioning) is difficult, costly, and time consuming. To succeed, these flash-based products must appeal to as many customers as possible. They must also appeal to the press, analysts, and investors. Are these constituencies looking for the same things? Are they still responding to technology unde

Cloning a virtual machine in vSphere fails with the error Number of virtual devices exceeds the maximum for a given controller
叶子

KB:(1016221) Symptoms When cloning a virtual machine or deploying from a template, cloning fails at approximately 90% on the vSphere Client with this error: Number of virtual devices exceeds the maximum for a given controller Cause This issue occurs when the Edit Virtual Hardware (Experimental) checkbox is selected as a cloning option in vCenter Server 4.0 and vCenter Server 4.0 Update 1. Resolution This is a known issue which is resolved in VMware vCenter Server 4.0 Update 3, for more information see the vSphere 4.0 Update 3 Release Notes. To resolve this issue, clone the virtual machine again without selecting the Edit Virtual hardware (Experimental) option. PS. vSphaer 4.1 still experience this kind of issue , the resolution still work.

Best Practices – Live Migration on Oracle VM Server for SPARC

Best Practices – Live Migration on Oracle VM Server for SPARC By jsavit on Jun 14, 2013 Ref: https://blogs.oracle.com/jsavit/entry/best_practices_live_migration Oracle VM Server for SPARC has supported live migration since 2011, providing operational flexibility for customers who need to move a running guest domain between servers. This can be extremely useful, but there’s confusion about when it is the right tool to use, when it isn’t, and how to best make use of it. This article will discuss some best practices and “do’s and don’ts” for live migration. Background Oracle VM Server for SPARC (originally, and still often called Logical Domains) provides live migration, which non-disruptively moves a running guest domain from one SPARC server to another. As with most things, this requires planning and has several technical requirements: Servers running compatible versions of Oracle VM Server for SPARC and firmware. Common network accessibility. N

IPv6 in XCP 1.6
Jeff Loughridge's Blog

The intent of this post is to document how to enable IPv6 in XCP 1.6 and manage the host using IPv6 transport. I hope Google leads many people to this page, as I wasn’t able to find anything else on the web on the subject. I’d like to see more people experimenting with IPv6 on XCP hosts. XCP 1.6 is built on an optimized Centos 6 dom0 kernel. Enabling IPv6 is not as simply a matter of editing files in /etc/sysconfig/ as you would for a typical Centos server. XCP takes over network configuration during system start-up. Fortunately, the process is very straightforward. To manage IPv6 networking on an XCP host, you must be comfortable with the ‘xe’ command line tools, as this cannot be performed using XenCenter. Here are the steps for enabling IPv6 and configuring an IPv6 address. Log in to the XCP host as root and execute ‘/opt/xensource/bin/xe-enable-ipv6 enable’. Reboot. Verify that an IPv6 link-local address appears on xenbr0 using ‘ip -6 addr

Licensing Syamatec Netbackup Client (7.x) for Virtualized Environment
VirTechGeek....

1. Using Symantec Netbackup 7.x for Virtualized environment. With the Symantec Netbackup 7.x release, it provides better virtual machine protection. Utilizing VMware‟s new vStorage API for Data Protection, NetBackup 7.x can perform a clientless backup that truly provides all the capabilities that normally require client software installed inside the system to be backed up (Windows). Efficient block level incrementals are now possible and there is no longer any requirement for a Backup Proxy or additional staging storage 2. Underlying Principles – Symantec Netbackup 7.x Virtual Infrastructure 3 provided a “quasi” backup API called VMware Consolidated Backup (VCB). It was not a true API in the traditional sense but it did provide for off-host virtual machine backups. With the vSphere 4 release, VMware made considerable modifications and renamed it the “vStorage API for Data Protection”. These new features worked well with existing NetBackup virtual machine protection technologies g

Six Reasons why 2014 might be the year of desktop virtualization in Financial Services
Theconfusedpundit's Blog

and two why it might not be (smiley) 1. The continuing low interest rate/low margin business environment is driving more focus in opportunities in reducing cost. Desktop virtualization solutions based on RDS/Xenapp can demonstrably save 25 per cent TCO, and more if the target community has second, Business Continuity desktops. This solution fits a lot of financial service communities such as branch, back office, call centres, and managers/executives/executive assistants. 2. The emergence of cloud based hosting of RDS/Xenapp and VDI will radically improve enterprise desktop virtualization ROI by solving the “two for one” problem. For Disaster Recovery reasons most firms are forced to provision two virtual desktop solutions (one in each data centre) for each physical desktop, which radically reduces ROI benefits. With Citrix merging Xenapp ands Xendesktop into Excalibur, a solution that prefers to be hosted on virtual servers, and demonstrating their solutions on the  Amazon
