VMware has released the next major update on VMware ESX 4.0 with the release of VMware ESX 4.0 Update 2.

The following information provides highlights of some of the enhancements available in this release of VMware ESX:

  • Enablement of Fault Tolerance Functionality for Intel Xeon 56xx Series processors— vSphere 4.0 Update 1 supports the Intel Xeon 56xx Series processors without Fault Tolerance. vSphere 4.0 Update 2 enables Fault Tolerance functionality for the Intel Xeon 56xx Series processors.
  • Enablement of Fault Tolerance Functionality for Intel i3/i5 Clarkdale Series and Intel Xeon 34xx Clarkdale Series processors— vSphere 4.0 Update 1 supports the Intel i3/i5 Clarkdale Series and Intel Xeon 34xx Clarkdale Series processors without Fault Tolerance. vSphere 4.0 Update 2 enables Fault Tolerance functionality for the Intel i3/i5 Clarkdale Series and Intel Xeon 34xx Clarkdale Series processors.
  • Enablement of IOMMU Functionality for AMD Opteron 61xx and 41xx Series processors— vSphere 4.0 Update 1 supports the AMD Opteron 61xx and 41xx Series processors without input/output memory management unit (IOMMU). vSphere 4.0 Update 2 enables IOMMU functionality for the AMD Opteron 61xx and 41xx Series processors.
  • Enhancement of the esxtop/resxtop utility— vSphere 4.0 Update 2 includes an enhancement of the performance monitoring utilities, esxtop and resxtop. The esxtop/resxtop utilities now provide visibility into the performance of NFS datastores in that they display the following statistics for NFS datastores: Reads/s, writes/s, MBreads/s, MBwrtn/s, cmds/s, GAVG/s(guest latency).
  • Additional Guest Operating System Support— ESX/ESXi 4.0 Update 2 adds support for Ubuntu 10.04. For a complete list of supported guest operating systems with this release, see the VMware Compatibility Guide.

Resolved Issues In addition, this release delivers a number of bug fixes that have been documented in the Resolved Issues section.

Hardware monitoring on ESXi servers

June 2, 2010

With the introduction of VMware ESXi, VMware had to provide a new way to monitor hardware resources. With the removal of the service console it is no longer possible to install dedicated agents to monitor hardware resources. To solve this problem VMware has leveraged the industry standard CIM technologies to enable interoperable remote hardware health monitoring on both the ESX and ESXi platforms.

CIM stands for Common Information Model and is is open standard that defines how computing resources can be represented and managed. CIM providers are used as the mechanism to provide management access to device drivers and underlying hardware. The following figure shows the CIM management model.

Hardware vendors, which include both the server manufacturers and specific hardware device vendors, can write providers to provide monitoring and management of their particular devices. VMware also writes providers that implement monitoring of server hardware, ESX/ESXi storage infrastructure, and virtualization-specific resources.

To enable specific hardware monitoring of your ESXi servers you can install the CIM provider of your server hardware vendor. You can download the latest versions of these providers here:

HP ESXi Offline Bundle for VMware ESXi 4.0 Update 1 (Version 1.3a)

Dell OpenManage offline bundle for VMware ESXi 4.0 Update 1 (Version 6.2.0)

To install the CIM provider you can use the vSphere Management Assistant (vMA). Use the following instructions to install the CIM provider:

  1. Log on to the vMA as an administrator and provide the password when prompted.
  2. Copy the CIM provider file to a directory on the vMA.
  3. Put the ESXi 4.0 host in maintenance mode.
  4. In the vMA, execute the following command:
    vihostupdate –server <IP address of ESXi 4 Host> -i -b <path to CIM provider file>
  5. Enter the root username and password of the ESXi 4.0 host when prompted. The command output displays a successful or a failed update.
  6. Restart the ESXi 4.0 host system.

After a successful installation you should see the additional sensors provided by your vendors CIM provider in the hardware status tab of your ESXi server (through the vSphere Client).


VMware Certified Advanced Professional

June 1, 2010

VMware has announced a new certification program to further prove your technical VMware knowledge. The new certification program is called VMware Certified Advanced Professional (VCAP) and is launched with two designations:

– VMware Certified Advanced Professional on vSphere 4 – Datacenter Administration (VCAP4-DCA)
The VCAP4-DCA is directed toward System Administrators, Consultants and Technical Support Engineers who can demonstrate their skills in VMware vSphere and VMware vCenter technologies in relation to the datacenter, as well as their knowledge of application and physical-infrastructure services and their integration with the virtual infrastructure.

 

 

 

 

 

– VMware Certified Advanced Professional on vSphere 4 – Datacenter Design (VCAP-DCD)
The VCAP-DCD is directed toward IT Architects and Consulting Architects who are capable of designing VMware solutions in a multi-site, large enterprise environment.  They have a deep understanding both of VMware core components and their relation to storage and networking, and also of datacenter design methodologies. They also possess knowledge of applications and physical infrastructure, as well as their relationship to the virtual infrastructure.

 

 

 

Both VCAP-DCA and VCAP-DCD certifications require to be a VMware Certified Professional 4 (VCP4).
