ESXi includes a firewall between the management interface and the network. To ensure the integrity of the host, VMware has reduced the number of firewall ports that are open by default. The ESXi firewall is enabled by default. At installation time, the firewall is configured to block incoming and outgoing traffic, except traffic for the default services. The firewall also allows Internet Control Message Protocol (ICMP) pings and communication with DHCP and DNS (UDP only) clients.
From the host Security Profile panel, you can configure firewall properties for this host. The Secuirty Profile panel lists the incoming and outgoing connections for the firewall and the port each service uses. The panel also displays the IP addresses that are allowed to connect for each service. You can modify the list of services and the allowed IP addresses for each service.
You can add supported services and management agents that are required to operate the host by adding ruleset files to the ESXi firewall configuration file directory /etc/vmware/firewall/. You open or close ports for these services by enabling or disabling the service on the host's security profile in the vSphere Client.

vSphere 5 Video - iSCSI User Interface support
I've recorded a video which will show you the new vSphere 5 iSCSI UI support and some other usability improvements. In vSphere 5 you'll have the ability to configure dependent hardware iSCSI and software iSCSI adapters along with the network configurations and port binding in a single dialog box using the vSphere Client. Full SDK access is also available for these configurations.
If you use the software or dependent hardware iSCSI adapters, you must configure connections for the traffic between the iSCSI component and the physical network adapters. Configuring the network connection involves creating a virtual VMkernel interface for each physical network adapter and associating the interface with an appropriate iSCSI adapter.
If your host has more than one physical network adapter for software and dependent hardware iSCSI, use the adapters for multipathing. You can connect the software iSCSI adapter with any physical NICs available on your host. The dependent iSCSI adapters can be connected only with their own physical NICs.

vSphere 5 Video – The vSphere Web Client
The vSphere Web Client, the Next-generation browser-based vSphere Client. A browser-based, fully-extensible, platform-independent implementation of the vSphere Client based on Adobe Flex. The vSphere 5.0 release includes both the new browser-based client and the Windows-based client available in prior releases. In this release, the browser-based client includes a subset of the functionality available in the Windows-based client, primarily related to inventory display and virtual machine deployment and configuration.
In this video I’ll show you how to log in to vCenter Server using the vSphere Web Client and manage your vSphere inventory. Before you can start to use the Web Client you first have to verify that the vCenter Server system is registered with the client. Just open a Web browser and enter the URL for the vSphere Web Client: http://server_name:8443/vsphere-client
The vSphere Web Client has improved immense comparing to the old Web Access interface and is completely rewritten in Adobe’s Flex. It’s supported on the following browsers:
- Microsoft Internet Explorer 7 and 8
- Mozilla Firefox 3.5 and 3.6
To deploy virtual machines in the vCenter Server inventory, you can create a virtual machine or clone an existing virtual machine. It’s also possible to deploy a Virtual Machine from a Template with the vSphere Web Client. Deploying a virtual machine from a template creates a virtual machine that is a copy of the template. The new virtual machine has the virtual hardware, installed software, and other properties that are configured for the template.
USB devices attached to the client computer running the vSphere Web Client or the vSphere Client can be connected to a virtual machine and accessed within it.

vSphere 5 Video - Storage DRS
- Configure a Datastore Cluster
- Set Storage DRS Automation Level
- Set Storage DRS Runtime Rules
- Create a Storage DRS Scheduled Task
- Using Storage DRS Rules
- Edit Virtual Machine Settings for a Datastore Cluster
- Apply Storage DRS Recommendations
- Add Storage to a Datastore Cluster
A datastore cluster is a collection of datastores aggregated into a single unit of consumption for an administrators. When a datastore cluster is created, Storage DRS can manage the storage resources comparable to how DRS manages compute resources in a cluster. As with a cluster of hosts, a datastore clusters is used to aggregate storage resources, enabling smart and rapid placement of new virtual machines and virtual disk drives and load balancing of existing workloads. When you create a VM you will be able to select a Datastore Cluster as opposed to individual datastores. Storage DRS provides initial placement recommendations to datastores in a Storage DRS-enabled datastore cluster based on I/O and space capacity.
During the provisioning of a virtual machine, a datastore cluster can be selected as the target destination for this virtual machine or virtual machine disk after which a recommendation for initial placement is done based on I/O and space capacity. Initial Placement in a manual provisioning process has proven to be very complex in most environments and as such important provisioning factors like current I/O load or space utilization are often ignored. Storage DRS ensures initial placement recommendations are made in accordance with space constraints and with respect to the goals of space and I/O load balancing. Although people are really excited about automated load balancing, it is Initial Placement where most people will start off with and where most people will benefit from the most as it will reduce operational overhead associated with the provisioning of virtual machines.
Ongoing balancing recommendations are made when one or more datastores in a datastore cluster exceeds the user-configurable space utilization or I/O latency thresholds. These thresholds are typically defined during the configuration of the datastore cluster. Storage DRS utilizes vCenter Server’s datastore utilization reporting mechanism to make recommendations whenever the configured utilized space threshold is exceeded. I/O load is evaluated by default every 8 hours currently with a default latency threshold of 15ms. Only when this I/O latency threshold is exceeded Storage DRS will calculate all possible moves to balance the load accordingly while considering the cost and the benefit of the migration. If the benefit doesn’t last for at least 24 hours, Storage DRS will not make the recommendation.
