Windows 7初探 - VHD支持 - [虚 拟 化]
Windows 7 增加了对 Virtual Hard Disks (VHD,虚拟磁盘)的支持,也就是说我们可以直接在 Windwos 7 中创建一个 VHD,并将其载入到当前系统中,使之操作起来像是在一个真实的硬盘之中。当然,我们也可以增加一个已经存在的 VHD,整个操作非常灵活!VHD 应用面越来越广,Windows 7 也将开始直接支持对 VHD 的使用,这意味着什么呢?也许,在未来我们存储文件不单单是放在一个文件夹中携带走,而更多的可能会创建一个 VHD,将相关的文件存储在其中,使我们能更加方面的携带,并且将其挂载到任意的 Windwos 7 系统上,甚至是在虚拟机种将其打开。该功能意义重大,微软360度虚拟化应用正在渗透到每个角落……
在 Windows 7 中创建或添加 VHD 非常简单,真个操作都在磁盘管理中进行,根据如下图所示我们可以轻松的创建一个自定义大小的虚拟磁盘,他可以是动态扩展的虚拟磁盘,也可以是一个固定大小的虚拟磁盘!当然我们也可以通过"Attach VHD"将一个现有的 VHD 添加进来。不过需要注意的是,在实际测试中发现,如果 Attach 的 VHDs 是一个之前 Virtual PC 或 Server 创建的会被拒绝使用。具体原因还有待官方资料解释! -

HA Advanced Options - [虚 拟 化]
http://www.yellow-bricks.com/2008/10/06/update-ha-advanced-options-2/
- das.failuredetectiontime - Amount of milliseconds, timeout time for isolation response action(with a default of 15000 milliseconds).
- das.isolationaddress[x] - IP adres the ESX hosts uses for it’s heartbeat, where [x] = 1‐10. It will use the default gateway by default.
- das.usedefaultisolationaddress - Value can be true or false and needs to be set in case the default gateway, which is the default isolation address shouldn’t be used for this purpose.
- das.poweroffonisolation - Values are False or True, this is for setting the isolation response. Default a VM will be powered off.
- das.vmMemoryMinMB - Higher values will reserve more space for failovers.
- das.vmCpuMinMHz - Higher values will reserve more space for failovers.
- das.defaultfailoverhost - Value is a hostname, this host will be the primary failover host.
- das.failuredetectioninterval - Changes the heartbeat interval among HA hosts. By default, this occurs every second (1000 milliseconds).
- das.allowVmotionNetworks - Allows a NIC that is used for VMotion networks to be
- considered for VMware HA usage. This permits a host to have only one NIC configured for management and VMotion combined.
- das.allowNetwork[x] - Enables the use of port group names to control the networks used for VMware HA, where [x] = 0 - ?. You can set the value to be ʺService Console 2ʺ or ʺManagement Networkʺ to use (only) the networks associated with those port group names in the networking configuration.
- das.isolationShutdownTimeout - Shutdown time out for the isolation response “Shutdown VM”, default is 300 seconds. In other words, if a VM isn’t shutdown clean when isolation response occured it’s being powered off after 300 seconds.
- das.bypassNetCompatCheck - Disable the “compatible network” check for HA that was introduced with Update 2. Default value is “false”, setting it to “true” disables the check.
Virtual Machine Monitoring HA advanced options
- das.failureInterval = The polling interval for failures. Default value is 30.
- das.maxFailureWindows = Minimum amount of seconds between failure. Default value is 3600 seconds, if VM fails within 3600 seconds VM HA doesn’t restart the machine.
- das.maxFailures = Maximum amount of VM failures, if the amount is reached VM HA doesn’t restart the machine automatically. Default value is 3.
- das.minUptime = The minimum uptime in seconds before VM HA starts polling. The default value is 120 seconds.

vRanger Pro - [虚 拟 化]
ESX的一款备份工具,国外很多人在用,普通反应还不错,收费的!
今天简单安装了下,全图形界面,感觉比VCB方便多了。。不知价格如何vRanger Pro
vRanger Pro is the recognized industry-standard backup and restore solution for virtualized environments. Administrators can schedule regular image-level backups of virtual or physical machines — while the machine is still running. Images can be stored either locally in the SAN or sent as compressed files over a WAN to remote locations to support disaster recovery strategies. vRanger Pro also enables restore of individual files efficiently with an explorer tree through which users can easily identify and "grab" needed files.http://www.vizioncore.com/vRangerPro.html
与VCB的主要区别:

一款vmware的备份软件,此软件是安装在service console上的,那基本上就代表了无法集中管理,适合小规模Vm环境
但是它是Free的,而且支持schedule task,应该比VCB强。国外有人推荐,我顺便贴出来share下
具体效果如何,目前比较忙,没时间测试。等测试完,再分享下原理和优缺点
VISBU is free backup software that is run from the Service Console that provides VMDK level backups of any VM on storage accessible by the host. The script can be targeted at any ESX server or VC server. The script is designed to be easy to use and offers all features from a simple menu driven interface, so a non-Linux administrator can use it with the minimum of fuss.
It provides email reports, automated restoration for every backed up VM, scheduling, is DRS aware, and supports backups to SMB, NFS, EXT3, iSCSI and SAN based volumes.

HP ProLiant Essentials Virtual Machine Management Pack - [虚 拟 化]
Overview



The ProLiant Essentials Virtual Machine Management Pack extends HP Systems Insight Manager capabilities to manage virtual machines. The Virtual Machine Management Pack provides central management and control of VMware®, Microsoft®, and Citrix virtual machines with physical host to virtual machine association, easy identification of VMs or host servers reaching high CPU, memory or disk utilization levels, highly flexible move capabilities that allows live moves (for some platforms) and moves to dissimilar host resources, and back up, template and alternate host capabilities that enable restoration of VMs on any available host.
VMM integrates with virtualization vendor management tools, such as VMware VirtualCenter, and VMM is the only solution available that out of the box can initiate VMware DRS to relocate VMs based on hardware predictive failure alerts.http://www.compaq.com/products/servers/proliantessentials/valuepack/vms/
