vSphere 6 Finally Arrived !!
After a long time in Beta its there for us, vSphere 6 is released for public. More details are in the press release.
vSphere 6 is packed with 650-plus new features and innovations that will empower users to virtualize applications with confidence by delivering increased scale and performance, breakthrough availability, storage efficiencies for virtual machines (VMs), and simplified management for the virtual data center. vSphere 6 is purpose-built for both scale-up and scale-out applications including newer cloud, mobile, social and big data applications. Following is a sample of the new features:
• Increased Scalability – Increased configuration maximums: Virtual machines will support up to 128 virtual CPUs (vCPUs) and 4TB virtual RAM (vRAM). Hosts will support up to 480 CPU and 12TB of RAM, 2,048 virtual machines per host, and 64 nodes per cluster
• Instant Clone* – Technology, built in vSphere 6.0, that lays that foundation to rapidly clone and deploy virtual machines, as much as 10x faster than what is currently possible today.
• Transform Storage for your Virtual Machines – vSphere Virtual Volumes* enables your external storage arrays to become VM-aware. Storage Policy-Based Management (SPBM) allows common management across storage tiers and dynamic storage class of service automation. Together they enable exact combinations of data services (such as clones and snapshots) to be instantiated more efficiently on a per VM basis
• vMotion Enhancements – Perform non-disruptive live migration of workloads across distributed switches and vCenter Servers and over distances of up to 100ms RTT. The astonishing 10x increase in RTT offered in long-distance vMotion now makes it possible for data centers physically located in New York and London to migrate live workloads between one another.
• Replication-Assisted vMotion* – Enables customers, with active-active replication set up between two sites, to perform a more efficient vMotion resulting in huge time and resource savings – as much as 95 percent more efficient depending on the size of the data.
• Fault Tolerance (up to 4-vCPUs) – Expanded support for software based fault tolerance for workloads with up to 4 virtual CPUs.

VMware vCloud Hybrid Service Now Generally Available in Europe
After a long time in beta phase finally vmware launched its GA version of their public cloud offering. Last year I was able to do an evaluation of this service, it was pretty good. In less than a year since launch, vCloud Hybrid Service has made substantial ground in the compliance space. To date, VMware has successfully attained ISO 27001 certification, completed examinations for HIPAA / HITECH, SOC 2 Type 1, SOC 1 (SSAE 16 / ISAE 3402) Type 2, and SOC 2 Type 2 on vCloud Hybrid Service.
Choose between a Dedicated Cloud or a Virtual Private Cloud
VMware vCloud Hybrid Service is available in two service options, giving you the flexibility and scalability you need to meet your organization’s requirements. A dedicated cloud provides you with a physically isolated infrastructure, giving you your own private cloud instance and the most control over your resources. A virtual private cloud provides you with logically isolated infrastructure, with fully private networking and resource pools. Below is the spec of the two service offerings Both the Dedicated Cloud and Virtual Private Cloud begin with a core subscription model. What is included in a “Core” package?
vCloud Hybrid Service Core packages include all the service components required to provision your service, but the capacities are different for Dedicated Cloud and Virtual Private Cloud. The capacities for each are as follows:
When I need more capacity than what is included in a Core or how do I add it? For that we need to add the resource as a UNIT, an UNIT is a predefined capacity like the below
VMware vCloud Hybrid Service — Data Protection is a simple yet secure policy-based backup and recovery solution for virtual-machine data and content that is hosted exclusively on VMware vCloud Hybrid Service.
Key Highlights:
24-hour recovery point objective (RPO)
Image-level restore granularity objective (RGO) per virtual machine
Fixed 30-day retention (onsite)
Industry standard AES-256 image-level encryption
Off-peak backup schedule (0000-0600 UTC-8)
No artificial limits on the number or size of registered virtual machines
Unlimited restore-operation requests
Install Emulex CIM Provider in VMware ESXi
As a part of VMware vSphere administration, you all will came across this term “CIM Provider” let see what it is …
The Common Information Model (CIM) system: CIM is the interface that enables hardware-level management from remote applications via a set of standard APIs.
The CIM is an open standard that defines how computing resources can be represented and managed. It enables a framework for agentless, standards-based monitoring of hardware resources for ESXi. This framework consists of a CIM object manager, often called a CIM broker, and a set of CIM providers. CIM providers are used as the mechanism to provide management access to device drivers and underlying hardware.
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. These providers run inside the ESXi system and hence are designed to be extremely lightweight and focused on specific management tasks.
The CIM object manager in ESXi implements a standard CMPI interface developers can use to plug in new providers. The CIM broker takes information from all CIM providers and presents it to the outside world via standard APIs, including WS-MAN (Web Services-Management). Figure 3 shows a diagram of the CIM management model.
So the Hardware vendors like Brocade, HP, DELL, IBM, EMC, Qlogic, Emulex etc will provide these modules and we have to install in the ESX/ESXi hosts.
Now let’s see how we can implement Emulex CIM in the vSphere infra. There are 3 main components in the Emulex Software solution for device management in the vSphere environment.
1- Emulex CIM Provider : This we have to install on the ESX/ESXi hosts, it will be available in offline bundle in ZIP format or in the VIB format.
2- Emulex OneCommand Manager (OCM) : This we can install in any windows virtual machine or in the vCenter server itself
OCM for VMware vCenter Server and Emulex CIM provider for ESX/ESXi host is free to download from the Management tab on the following pages.
3- Emulex vCenter server plugin : Once every thing configured and ready, you can see the OCM plugin in the vSphere console and just enable the plugin.
Installation Steps
1- Download the corresponding CIM provider for the ESXi based on your version, in my case it is vSphere 5 update 2 and download the file “CIM Provider Package 3.8.15.1” and extract the ZIP file.

The release notes and user manual are there for more information
2- Upload the offline bundle ZIP file (VMW-ESX-5.0.0-emulex-cim-provider-3.6.12.1-01-offline_bundle-799300.zip) to any of the Datastore via Putty or vSphere Client Datastore browser, to an ESX/ESXi host.
3- Login to the ESXi shell via SSH, and first check the files are copied correctly and their location
~ # cd /vmfs/volumes/Templates/emulex/
/vmfs/volumes/50bd9d4d-adf00e08-78e9-002655e66551/emulex #

ESX/ESXi – Administration TIPS
How to disable or Stop the CIM agent on the ESX/ESXi host ?
Note: The CIM agent is the process providing hardware health information. Disabling this service will disable the hardware health status.
To disable the CIM agent on an ESXi host: Log in to the ESXi shell as the root user.
chkconfig sfcbd-watchdog off
chkconfig sfcbd off
/etc/init.d/sfcbd-watchdog stop
Note: Changing the chkconfig disables the sfcbd service and is persistent across reboots.
To re-enable the CIM agent on the ESXi host, run these commands:
chkconfig sfcbd-watchdog on
chkconfig sfcbd on
/etc/init.d/sfcbd-watchdog start
Note: To check the status of the agent on ESXi, run the below command.
/etc/init.d/sfcbd-watchdog status
For troubleshooting purpose you can use the below commands to restart the CIM related services in ESXi host
#/etc/init.d/wsman restart
#/etc/init.d/sfcbd-watchdog start
Disabling a Single ESXi CIM provider when it fails or is unstable.
To see the CIM providers installed on your ESXi host:
- Log in to the ESXi shell as the root user.
- Run the command:
esxcli system settings advanced list | grep CIM - You see output similar to:
Path: /UserVars/CIMEnabled
Description: Enable or disable the CIM service
Path: /UserVars/CIMLogLevel
Description: Set the log level of the CIM Service
Path: /UserVars/CIMWatchdogInterval
Description: Set the watchdog polling interval for the CIM Service
Path: /UserVars/CIMvmw_sfcbrInteropProviderEnabled
Description: Enable or disable the CIM vmw_sfcbrInterop provider
Path: /UserVars/CIMvmw_hdrProviderEnabled - Disable a CIM provider by running the command:
esxcli system settings advanced set -o /UserVars/CIMProviderName -i 0
Note: To re-enable the CIM provider, run the command:
esxcli system settings advanced set -o /UserVars/CIMProviderName -i 1 - To allow the changes to take effect, restart the SFCBD agent by running the command:
/etc/init.d/sfcbd-watchdog restart
I will post a details blog regarding the use of OneCommand manager
