Microsoft Windows Server 2008 goes virtual with Hyper-V Microsoft Windows Server 2008 goes virtualne s Hyper-V

As part of the Windows Server 2008 launch, Microsoft officially ushers in the era of true Windows server virtualization with Kot del sistema Windows Server 2008 začela Microsoft uradno vratarje v dobi pravega strežnika Windows z virtualizacijo Hyper-V Hyper-V . . It used to be that virtualization was only found in the datacenters of companies like Amazon and their Včasih je treba, da je bilo le za virtualizacijo na voljo v podatkovna središča podjetij, kot so Amazon in njihovih EC2 EC2 computing cloud. cloud computing. Now, Microsoft brings virtualization to the rest of us. Zdaj, Microsoft prinaša virtualizacijo za nas ostale. Windows Server 2008 and Hyper-V come at the perfect time. Windows Server 2008 in Hyper-V prišel ob pravem času. With processor architecture shifting away from increasing speeds and towards multiple cores, virtualization will be a significant server-space trend in the near future. Z procesorja arhitekturo ukinjena večje hitrosti in smeri več jedra, bo virtualizacijo pomemben strežnik-trend prostora v bližnji prihodnosti.

Multiple Servers. Multiple Strežniki. One Box. One Box. Lots of RAM. Veliko RAM.

Hyper-V is a type-1 (native) hypervisor, meaning it runs at the root level with direct control over the server's hardware. Hyper-V je tipa 1 (native) hypervisor, kar pomeni, da teče na korenski ravni z neposrednim nadzorom nad strojno opremo strežnika. Virtual operating systems run independently of each other as partitions just above the Hyper-V stack. Virtual operacijski sistemi delujejo neodvisno drug od drugega, kot pregrade tik nad Hyper-V stack. With server virtualization, you are essentially running multiple servers on one physical box. Z virtualizacijo strežnikov, ste v bistvu izvaja več strežnikov na eni fizični škatli. Previously, the only server virtualization product available from Microsoft was Virtual Server 2005 which ran as a type-2 (hosted) hypervisor over a macro operating system like Windows Server 2003. Pred samo virtualizacijo strežnika izdelek na voljo Microsoft Virtual Server 2005, ki je potekalo kot tipa 2 (gostila) hypervisor v makro kot operacijski sistem Windows Server 2003. This meant the Virtual Server 2005 hypervisor did not have direct hardware access. To je pomenilo, Virtual Server 2005 hypervisor niso imeli neposrednega dostopa do strojne opreme. Guest operating systems within Virtual Server 2005 were essentially threaded applications running through a macro-kernel. Gost sistemi, ki delujejo znotraj Virtual Server 2005 so bile v glavnem z navojem aplikacije, ki teče skozi makro-jedra. Hyper-V replaces the operating system layer and runs as a true type 1 micro-kernel hypervisor. Hyper-V nadomešča plast operacijski sistem in deluje kot pravega tipa 1 mikro-kernel hypervisor.

There are two key requirements for running Hyper-V: an x64 edition of Windows Server 2008 and a 64-bit processor with hardware assisted virtualization extensions (like those found in the Obstajata dve ključni zahteve za vožnjo Hyper-V: x64 različico operacijskega sistema Windows Server 2008 in 64-bitni procesor s pomočjo strojne razširitve za virtualizacijo (kot jih najdemo v Intel VT Intel VT or ali AMD-V AMD-V line of processors). linije procesorjev). Although Hyper-V requires a 64-bit working environment, guest operating systems may be 32 or 64-bit. Čeprav Hyper-V zahteva 64-bitni delovno okolje, gostujoči operacijski sistemi se lahko 32 ali 64-bitni. Supported guest operating systems (the ones you want virtualized) include the following*: Podprti operacijski sistemi gost (tiste, ki jih želite virtualiziranih), vključujejo naslednje *:

• Windows Server 2008 Windows Server 2008
• Windows Server 2003 Windows Server 2003
• Windows 2000 Server Windows Server 2000
• Windows Vista Windows Vista
• Windows XP Professional Windows XP Professional
• SUSE Linux Enterprise Server 10 SUSE Linux Enterprise Server 10
  * Other operating systems may work but are not supported in an official capacity * Drugi operacijski sistemi lahko dela, vendar niso podprte v uradni vlogi

You may have noticed that Hyper-V requires a 64-bit environment. Morda ste opazili, da Hyper-V zahteva 64-bitno okolje. Not surprising given the 4 GB memory limitation found in 32-bit architecture. Ni presenetljivo glede na 4 GB pomnilnika omejitev na voljo v 32-bitno arhitekturo. Four gigabytes divided over multiple instances just doesn't cut it anymore. Štiri gigabajta razdeljena na več primerkov samo ne seka več. Fortunately, Windows Server 2008 Enterprise and Datacenter editions with Hyper-V can support up to 2 terabytes of physical memory and 64 gigabytes of memory per virtual instance. Na srečo, lahko Windows Server 2008 Enterprise in Datacenter naklada s Hyper-V podporo do 2 TB fizičnega pomnilnika ter 64 gigabajtov spomina na virtualnih stopnji. That's a lot of memory! To je veliko spomina!

Quick Migration and High Availability Quick Migracije in High Availability

Virtualized servers will benefit almost immediately from the ability to quickly migrate from one physical server to another. Virtualiziranih strežnikov bodo imeli skoraj takoj od sposobnosti, da se hitro selijo iz enega fizičnega strežnika na drugega. Microsoft Hyper-V with Quick Migration can save the state of a guest virtual operating system to shared storage, move the storage connection from one server to another, and then restore the image to the new server. Microsoft Hyper-V z Quick Migracije lahko shranite stanje gost virtualni operacijski sistem za skupno skladiščenje, premaknite shranjevanje povezavo iz enega strežnika v drugega, in nato ponovno vzpostaviti podobo, da novi strežnik. Quick Migration works in tandem with the Windows Server 2008 Enterprise and Datacenter Clustering service to provide high availability and rapid disaster-recovery capabilities for your clustered servers. Quick Migration deluje skupaj z Windows Server 2008 Enterprise in Datacenter Clustering storitev za zagotavljanje visoke razpoložljivosti in zmogljivosti nesreče hitro obnovo za vaše gruče strežnikov. Whether it's planned (maintenance) or unplanned (disaster recovery), the use of virtualization technology increases server uptime and availability. Ali je to načrtovano (vzdrževanje) ali nenačrtovana (za obnovitev), uporaba tehnologij za virtualizacijo povečanja dostopnosti in dosegljivosti strežnika.

Virtual Appliances Virtual Appliances

The virtual appliance is a promising new development available with virtualization. Virtualna naprava je obetaven nov razvoj na voljo z virtualizacijo. Vendors can package an operating system and all necessary software to run their product into a virtual “black box” image. Prodajalci lahko paket operacijskega sistema in vse potrebne programske opreme za vodenje svoj proizvod v virtualni "črno skrinjico" image. This image can then be deployed on different machines even if the configuration is different. Ta slika se nato lahko uporabijo na različnih strojih, tudi če je drugačno konfiguracijo. Virtual appliances can reduce the installation, configuration, and maintenance costs associated with managing and deploying multiple layers of software. Virtual naprav lahko zmanjša namestitve, konfiguracije, vzdrževanja in stroškov, povezanih z upravljanjem in uporabo večih plasti programske opreme. The Microsoft Virtual Hard Disk Microsoft Virtual Hard Disk (VHD) test drive program is a great example. (VHD) preizkus vožnje program je odličen primer. From the VHD website, “The Microsoft Virtual Hard Disk (VHD) format is the common virtualization file format that provides a uniform product support system, and provides more seamless manageability, security, reliability and cost-efficiency for customers. Iz spletne strani VHD, "Microsoft Virtual Hard Disk (VHD) oblika je skupni datoteke virtualizacijo obliki, ki omogoča enoten sistem za podporo izdelka, in zagotavlja bolj nemoteno upravljivosti, varnost, zanesljivost in stroškovno učinkovitost za stranke. The VHD format captures the entire virtual machine operating system and the application stack in a single file.” As virtualization becomes more prevalent, we'll begin to see even more innovative and useful virtual appliances. Format VHD zajema celoten stvaren stroj operacijski sistem in uporabo stack v eni datoteki. "Kot virtualizacijo postane bolj razširjene, bomo začeli videti še bolj inovativne in uporabne virtualne naprave.

Server virtualization represents the next logical step in efficient server-space progression. Server virtualizacijo predstavlja naslednji logični korak v učinkovito server prostora napredovanje. As servers begin shifting to multi-core architecture and 64-bit platforms, virtualization should become an increasing factor in optimizing server workload performance and reducing costs, especially as server proliferation becomes a growing problem. Kot pomočnik začeli seli v multi-core arhitekture in 64-bitne platforme, bi morala postati virtualizacijo vse pomembnejši dejavnik pri optimizaciji učinkovitosti in delovne obremenitve strežnika zmanjšanje stroškov, zlasti ker strežnik orožja postane vse večji problem. What was once strictly within the realm of datacenters and development labs is now becoming IT reality. Kar je bilo nekoč strogo v sferi podatkovna središča in razvoj laboratorijev IT je zdaj postaja resničnost. Although there are some performance issues to consider, you might find the advantages of virtualization are well worth the investment. Čeprav obstaja nekaj vprašanj, da preuči učinkovitost, lahko najdete prednosti virtualizacije, so dobro vredno naložbo.
