vSphere Storage Appliance (VSA) licensing information

(VSA) VMware vSphere Storage Appliance provides virtual shared storage volumes without the hardware. vSA runs as a virtual machine on vSphere, in multiple hosts. vSA is only compatible with vSphere 5.

Licensing Details
•vSA is licensed on a per-instance basis. Each vSA instance supports up to 3 node.
•At least two nodes needs to be part of a vSA deploymen.
•vSA is supported by all vSphere 5 edition.
•There are no upgrades in vS.
•vSA can only run with Essentials Plus or any vSphere Edition.
•vSA must be purchased for the vCenter Server edition that it will run on – vCenter Essentials (sold only with Essentials Plus), vCenter Foundation, or vCenter Server.
•If you apply the old vCenter Server license key after installing vSA, the vSA disappear.
•You must reapply the vSA key if you upgrade from vCenter Foundation to vCenter Standard. You have to contact the Licensing Support team to get a new vSA key compatible with the new vCenter Server edition. This exchange is at no charge.
•The vRAM used for vSA factors in to your vRAM entitlement.
•vSA must be deployed on the same vCenter Server.
•The vSA virtual machine counts as a protected virtual machine.

vSphere 5 – Using Multiple Network Adaptors for vMotion

vSphere 5 adds a multi–network adaptor feature that enables the user to utilize multiple network adaptors for vMotion.

In the screen shot below, you can see that there are multiple vMotion vmkernel ports, with 1 active vmnic, and 3 standby nics.

Test results, show that migration times can be dramatically reduced when using this feature.

The VMkernel will transparently load balance vMotion traffic over all of the vMotion-enabled vmknics to saturate all of the connections. In fact, even where there is a single vMotion, VMkernel uses all of the available network adaptors to spread the vMotion traffic

VMware vCenter Server 5.0

Below is a list of new features in vCenter Server 5.0

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. 

vCenter Server Appliance.

A vCenter Server implementation running on a pre-configured Linux-based virtual appliance. This appliance significantly reduces the time required to deploy vCenter Server and associated services and provides a low-cost alternative to the traditional Windows-based vCenter Server.

The vCenter Server Appliance has the following limitations:-

  • No Update Manager
  • No Linked-Mode
  • No support for the VSA (vSphere Storage Appliance)
  • Only support for Oracle as the external database
  • Embedded database, DB2, only supports 5 hosts and 50 VMs
  • No support for vCenter Heartbeat

Inventory Extensibility.

VMware customers and partners can extend vCenter Server in multiple ways, including the inventory, graphical user interface, and agents. vCenter Server includes a manager to monitor the extensions. By deploying extensions created by VMware partners, you can use vCenter Server as a unified console to manage your virtualized datacenter.

Solution Installation and Management.

The vCenter Solutions Manager provides a consistent interface to configure and monitor vCenter-integrated solutions developed by VMware and third parties. It provides a simpler installation, configuration, and monitoring interface for managing solutions. Using the new vSphere ESX Agent Manager, you can deploy, update, and monitor vSphere agents on ESXi hosts. vSphere agents inter-operate efficiently with other vSphere features such as maintenance mode and distributed power management.

Enhanced logging support.

vSphere 5.0 adds several enhancements to system message logging. All log messages are now generated by syslog, and messages can now be logged on either local and/or one or more remote log servers. A given server can log messages from more than one host. Log messages can be remotely logged using either the Secure Sockets Layer (SSL) or TCP connections. The vSphere syslog listener is available as an optional plug-in to vCenter on Windows; in the vCenter Virtual Appliance (VCVA), logging is accomplished using the native syslog-ng facility. With vSphere 5.0, log messages from different sources can be configured to go into different logs for more convenience. Configuration of message logging can also be accomplished using ESXCLI in addition to the vSphere client.

VMware Announcement VSphere 5

Was on the #vmwarecloud webinar today. VMware announced VSphere 5 has been released, and will be on G A in around 30 days’ time from today. Already blogged on features previously, but a few features were discussed in detail. VMware Storage Appliance looks to be good for SMB market, to leverage the cost of local disk on ESX hosts. Also SRM 5 application level replication looks to be good.
New Licence model, using pooled VRAM. No Advanced edition in the new edition, and existing customers will get enterprise edition.

Will be blogging in detail on features once i digest it all myself.
