There are some new enhancements with Hyper v you should be aware of. Dynamic Memory- A new feature of Hyper-V™ introduced in SP1 for Windows Server® 2008 R2 that enables Hyper-V hosts to dynamically adjust the amount of memory available to virtual machines in response to changing workloads. The benefits of Dynamic Memory include higher virtual machine consolidation ratios and increased flexibility for managing virtualized workloads.
Microsoft RemoteFX– Introduces a new set of remote user-experience capabilities that enable a media-rich user environment for virtual and session-based desktops. RemoteFX can be deployed to a range of thick and thin client devices, enabling cost-effective, local-like access to graphics-intensive applications. RemoteFX also supports a broad array of USB peripherals to improve the productivity of users of virtual desktops. Microsoft RemoteFX leverages the power of virtualized graphics resources and advanced codecs to recreate the fidelity of hardware-assisted graphics acceleration, including support for 3D content and Windows Aero®. Multi-Site Disaster Recovery Automation for Hyper-V – not so new, but still important. For automated failover and recovery of Hyper-V workloads, organizations can combine StorageLink Site Recovery technology with Microsoft failover clustering to create a geographically dispersed (or multi-site) cluster. Together, StorageLink Site Recovery and Windows Server® 2008 provide a disaster recovery solution that automatically detects local application or hardware failures and responds with the appropriate failover measures.
Microsoft on Tuesday released 17 updates that fix 40 separate vulnerabilities, several of which are being exploited. Only two of the updates fix vulnerabilities rated critical. The two critical updates include MS10-090, which fixes seven bugs in Internet Explorer. Every supported version of IE on every supported platform is affected by at least one critical vulnerability, and client versions have at least three. Six of the seven are memory corruption vulnerabilities and the seventh is a cross-domain information disclosure that is being exploited in the wild. At least six of these were reported by professional researchers. The second critical vulnerability is MS10-091, wihch includes three bugs in the OpenType font driver that could allow for remote code execution. All versions of Windows are affected, although on Windows XP and Server 2003 only a privilege elevation is possible. Fourteen of the remaining 15 vulnerabilities fixed today have a maximum rating of important:
* MS10-092: A local user can elevate privileges by exploiting a bug in the Task Scheduler.
* MS10-093: This is one of the Insecure DLL loading vulnerabilities, affecting Windows Movie Maker on Vista. The user would have to load an untrusted file from a network share or WebDAV site.
* MS10-094: Another Insecure DLL loading vulnerability, this one is in Windows Media Encoder. The user would have to load a WME profile (.prx) file from an untrusted network share.
* MS10-095: An Insecure DLL loading vulnerability in Windows Live Mail and Live Writer.
* MS10-096: An Insecure DLL loading vulnerability in the Windows Address Book.
* MS10-097: An Insecure DLL loading vulnerability in the Windows Internet Connection Signup Wizard in XP and Server 2003.
* MS10-098: Six separate vulnerabilities in Windows related to Kernel Mode Drivers, one publicly-disclosed, could allow a user who is logged in locally to elevate privilege.
* MS10-099: The NDProxy component of Routing and Remote Access in Windows XP add Server 2003 is vulnerable to an elevation of privilege.
* MS10-100: An error in the way the Consent User Interface in Windows Vista, Windows 7, and Windows Server 2008 processes certain registry data could lead to privilege elevation.
* MS10-101: A null dereference in netlogon in Windows Server could lead to a denial of service.
* MS10-102: An authenticated user in a guest VM could send a packet, which would cause a denial of service in Hyper/V.
* MS10-103: Five vulnerabilities in all versions pf Microsoft Publisher could lead to remote code execution.
* MS10-104: A user can trigger remote code execution on Sharepoint Server 2007 with a special SOAP request. The affected services, Document Conversions Load Balancer Service and Document Conversions Launcher Service, are not enabled by default, and the user context of the attacker would be guest with access only to the temp directory.
* MS10-105: Seven vulnerabilities in the graphics import filters in Office XP, Office 2003, the Office Converter Pack and Works 9 could allow remote code execution. In a strange move, Microsoft is recommending that Office 2007 and 2010 users apply the patch as well, even though it says those versions are not vulnerable.
* The final update, MS10-106, fixes a single vulnerability rated moderate. Authenticated users could trigger a denial of service in Exchange 2007 Server. The server would have to be manually restarted.
Removable Disk Drives vs. DVDs and USB Drives as Archive and Backup MediaThe benefits of using high-capacity removable disk cartridges are clear when compared to alternative media such as tapes, DVDs, and USB drives. Rugged, removable disk media such as the Dell PowerVault RD1000 cartridges are very durable, built to withstand a fall from nearly one meter. They are also small and lightweight and can be easily stored off-site for better disaster recovery protection.
The drives themselves, when ordered with a Dell server, add only about $200 to the cost. External drives, which can be connected to any server or workstation via USB, are only about $30 more. The removable disk drive cartridges are typically available in 160GB, 320GB, 500GB and 640GB native capacities. With data compression, a cartridge can often backup twice that amount of data, or more.
An archived collection of disk cartridges takes considerably less shelf space than a similar amount of DVDs or CDs — it would take 36 standard DVDs to hold the volume of a single 320GB removable disk cartridge. This solution is also easily expandable – if you outgrow the 320GB cartridges, for example, just start using 500GB cartridges. There’s no need to buy a new drive, and you can still read the files archived on the smaller cartridges.
Combined with the backup software best suited to your needs – such as Symantec Backup Exec, Acronis Backup and Recovery, or the backup software native to Windows Server 2008 and Windows 7, removable disk cartridges provide easy-to-use backup and disaster recovery capabilities to protect files, as well as all user data to help provide faster restores and reduced downtime.
