The installer informs you that an earlier version of vCenter Server is on the computer and will be upgraded.
Each virtual machine has a compression cache where vSphere can store compressed pages of 2KB or smaller size.
A few minutes ago VMware has released the new version of VMware vSphere, version.1.
By implementing the above, like Scalable vMotion, Wide VM Numa, Memory Compression, features VMware has realized a significant performance improvement.LRO support translates in a 5-30 performance improvement my book world edition 2 in throughput usage and 40-60 decrease in CPU cost depending on workloads.That's very interesting I think.VMware support policy for the VMware Infrastructure 3 platform.This results in a performance regain of 15 when theres a fair amount of memory over-commitment and a regain of 25 in case of heavy over-commitment.VSphere.1 also introduces asynchronous transmission of network packets through a new TX Wordlets scheduler.Additional performance enhancements vSphere.1 introduces additional improvements in other areas like Storage vMotion, thanks to the support for 8GB Fibre Channel HBAs.Depending on workloads and configurations, the performance improvement is up.Wide VM Numa The vSphere.1 numa scheduler has been reworked to improve performance when a certain virtual machine needs more cores than the ones available on a certain numa node, assuming that the server has a large number of numa nodes.To upgrade, confirm that your database is supported dell studio 17/1749 power button with vCenter Server.1, and back up your supported database, SSL certificates, and vCenter Server configuration.Transparent Memory Compression vSphere.1 introduces a new memory over-commit technique called expeed 4 image processor Transparent Memory Compression (TMC) that compresses on the fly the virtual pages that should be otherwise swapped on disk.Support is extended in accordance with the.VMware will continue to provide technical support for VMware ESX according to the.See the vSphere Resource Management Guide.It translates into a throughput improvement of 2X for intra-VMs traffic and up to 10 throughput improvement for VM-to-host traffic.You can upgrade from vCenter Server.0 to vCenter Server.1 on the same system if it is 64 bit.Another cool feature I wanted to highlight is the Memory Compression feature.VMware reports a performance improvement of up to 89 in CPU read cost and 83 in CPU write cost.At the end of the installation process administrators are redirected online to download the client; ESXi installation can be scripted.As of the next version there will only be two versions, ESXi embedded and installable.New major or minor versions of the vSphere platform beyond vSphere.1 will not be supported with VCB.
Scalable vMotion vSphere.1 supports up to 8 concurrent virtual machines live migrations and VMware seems to have renamed the feature in Scalable vMotion.
This is useful only for Linux guest operating systems that support LRO.
