Intel to acquire McAfee for 7.68 billion.

Nathan Simon Nathan Simon Profile: Nathan Simon

Something quite interesting… looks like Intel will use McAfee to scan at the bit level with vPro.

In a statement, Intel said the acquisition reflects that security is now a fundamental component of online computing. Intel wants to bring computing security down to the chipset level, calling it “hardware-enhanced security,” and Intel will make security a strategic priority for the company alongside performance and energy-efficiency.

They say that McAfee will still act as its own company reporting to Intel’s Software and Services Group.

Hints to Troubleshooting iSCSI and ESX issues

Nathan Simon Nathan Simon Profile: Nathan Simon

Hey everyone, recently I Ran into an issue where an iSCSI datastore became disconnected from one of my ESX Hosts. All other hosts could see them fine. The datastores reside on an HP All-in-One Storage Server. Once of the most important things to do is first check physical connections to the iSCSI network, if you have it VLAN’d that way. Second goto the service console, be it directly or using the VMCLI(VMware Command Line Interface) and see if the vmkernel port assigned to you ESX host can ping the iSCSI target host, the command is vmkping. VMkping will send a ping request solely from the vmkernel port to the iSCSI target. If the communication is working OK, then you know its the Windows host. I had to go into the HP Aio and remove the iSCSI target and re-add it, make sure you document all settings! Once that was done, I ran a rescan on the configure>storage tab and I was good to go. Another quick way to see that the host is having errors is hitting F12 on an ESX Host, this will show you a multitude of information that you don’t necessarily need, but it will also show you the most recent errors as well. Good Luck!

Windows 7 and DirectX 11

Nathan Simon Nathan Simon Profile: Nathan Simon

We all do it, PC gaming, well finally there is a graphics format that will improve on performance while starting to make games look more real.

AMD has been aggressively shipping DirectX 11 GPUs in almost every price category, while cards based on Nvidia’s new GTX 470 and GTX 480 DX11 parts are finally becoming available. Meanwhile, Windows 7’s sales ramp has been extraordinary—the fastest-selling Microsoft OS in history. Given that Windows 7 is what Vista should have been, it’s also arguable that DirectX 11 is what DX10 should have been.

When DirectX 10 games hit the streets, the new API gave users marginal improvements in image quality alongside huge performance decreases. The tiny gain in visual fidelity didn’t really make up for the performance hit. On the other hand, DirectX 11 brings users some very cool potential eye-candy improvements, but also promises better performance—even if you don’t have a DirectX 11 GPU.

My buddy just got an Nvida GTX 470 card, I cant wait to see Dirt 2 on it! Check out the full story here along with great visual comparisons of games with and without tessellation.

Enhanced Vmotion Capabilities and You!

Nathan Simon Nathan Simon Profile: Nathan Simon

Sometimes you need to enable EVC to make sure vMotion plays nice with your ESX Hosts, I used this document as a reference point to make sure everything would work once EVC was enabled. Check it out.

For those questioning, “Can I enable this on the fly without downing any ESX Hosts or VMs?” The answer is yes you can enable it on the fly, just make sure to comply with the compatibility results when selecting your processor type, be it Core2Duo or Core2Duo 45nm etc…

Nathan Simon Nathan Simon Profile: Nathan Simon

ILO2 has been update a little while back, if you are still running an older version of ILO2 I would recommend upgrading as it fixes some ASR shutdown issues amongst other enhancements.

Added the following new features:

  • New HP Intelligent Power Distribution Unit 
  • Fully Qualified Domain Name (FQDN) for imported certificates
  • A Recovery Payload that will help users recover iLO 2 from a failed firmware upgrade via FTP. Additional details can be found in the new User Guide which can be found at http://www.hp.com/go/ilo
  • “IPMI over LAN” functionality. The IPMI 2.0 RMCP+ (or Linux ipmitool “lanplus”) protocol is supported with this release.
  • IPMI Serial Over LAN (SOL)
  • Data Center Manageability Interface (DCMI) v1.0 specification
  • Enhanced the “in band” Intelligent Platform Management Interface (IPMI) to comply with the IPMI specification version 2.0

Go here to download the firmware, extract to a folder then upload the firmware via ILO2, yes you can do the upgrade live, only ILO will be reset.

Veeam and Consolidate Helper- 0

Nathan Simon Nathan Simon Profile: Nathan Simon

A lot of people run into issues with Veeam and the cause can sometimes be the Consolidate Helper. Here is an explanation from Veeam.

“it is automatically created by ESX host during snapshot management process. Whether the job fails due to an error, or manually stopped, Veeam Backup goes through the same (and only) cleanup procedure that would remove snapshot we have created during backup (“VEEAM BACKUP TEMPORARY SNAPSHOT”) – you can easily confirm this snapshot appearing first, and then disappearing.”

So basically you should disable any Veeam jobs that are scheduled and remove the offending “snapshot” Be wary though that when removing a snapshot, it can hog the disk on the ESX host, and in-turn may cause issues with any servers on that host.

Veeam Restore Issue and Resolution

Nathan Simon Nathan Simon Profile: Nathan Simon

When you go to restore a VM using Veeam Backup 4.x.x you may get the following error.

Failed to validate command “OpenPortIn for firewall port xxxx”

The resolution is simple and as follows.

Under the ESX Host properties you are trying to restore to, enable “Elevate to Root” and “Add account to sudoers file automatically

Once you have completed this step you should be good to go.

New Blackberry 9800

Nathan Simon Nathan Simon Profile: Nathan Simon

I’ve been noticing a lot of stories popping up about Blackberry’s device that should help businesses keep away from iPhones. Here is an insert with some information and specs on the new phone.

RIM is expected to announce details of the iPhone-esque BlackBerry 9800 next week. Don’t hold your breath that for the BlackBerry smartphone to blow the iPhone or Android smartphones out of the water, but as long as the device can hold its own it should be a winner for RIM.

The phone will be having a 3 inch display touch screen with 360 x 480 pixels having 65K colors, 5 megapixel camera with Liquid lens technology, Touch sensitive optical track pad, HSDPA and GSM facility, 3.5 mm audio jack, micro SD slot that can handle up to 16 GB of files, GPRS, EDGE, Bluetooth, microUSB v2.0 and Li-Ion 1050 mAh battery. It also includes Wi-Fi 802.11n, a 4GB on board storage for more space for downloaded files, 512 MB RAM. It also has a media player, pod cast apps and Upgraded Web kit browser that is really cool and entertaining stuff that fits any user, ensuring happy and comfortable use.

Currently I have been using my Bold 9700 with a hybrid operating system, some of OS 5 and some of OS 6. I must say that there are some key benefits to OS 6.
