Limiting Resources in VMWare Vsphere Virtual Machine

-

 



VM အတွက် resource usage limit သတ်မှတ်ပေးလိုက်တဲ့အခါ:

·         VM ဟာ သတ်မှတ်ထားတဲ့ limit ထက် resource တွေကို အသုံးပြုခွင့်မရှိတော့ပါဘူး။

·         Host system က resource ပိုလျော့နေတယ်ဆိုရင်တောင်, VM ဟာ သတ်မှတ်ထားတဲ့ limit နဲ့ကန့်သတ်ခံနေရတတ်ပါတယ်။

·         ဒီလိုဖြစ်တဲ့အတွက်, ပိုမိုအသုံးဝင်စွမ်းဆောင်နိုင်တဲ့ resource တွေကို ကောင်းစွာ အသုံးမချနိုင်ဘဲ idle ဖြစ်နေတတ်ပါတယ်။

ဥပမာအနေဖြင့်: Host system မှာ CPU 40GHz ရှိတယ်၊ သင့် VM ကို CPU usage limit 10GHz သတ်မှတ်ထားတယ်လို့ယူပါစို့။

·         VM ဟာ မိမိ workload အတွက် 10GHz ထက်ပိုလိုအပ်တာမျိုးဖြစ်လာရင်, သတ်မှတ်ထားတဲ့ 10GHz limit ပြည့်တဲ့အထိပဲ resource ကို အသုံးပြုနိုင်တယ်။

·         Host မှာ ကျန်နေတဲ့ 30GHz ဟာ အချို့ workload မရှိဘဲ idle ဖြစ်နေတတ်ပါတယ်။ ဒါက resource wastage ကို ဖြစ်စေတယ်။

ဒီလိုကြောင့် resource limit သတ်မှတ်တဲ့အခါ, သင့် workload တွေနဲ့ resource management ကို နားလည်စွာ balance လုပ်ဖို့လိုပါတယ်။

Prerequisites for Exchange Server 2010 Installation

-
Before you begin to setup Microsoft Exchange 2010 environment, your organization must have the following prerequisites. Active Directory Domain Service (ADDS)  An Active Directory (AD) infrastructure running on Windows Server 2008 or Windows Server 2012 must be in place before an organization can deploy Exchange Server 2010. Exchange Server depends on the services provided by AD to successfully function and the design and implementation of the AD environment can have an enormous impact on the success of the Exchange Server deployment. Mistakes made in the planning or implementation of AD can be costly and difficult to correct later. If AD is already deployed, it is important that the team designing the Exchange Server infrastructure have a solid understanding of the existing AD environment. Organizations with an AD infrastructure already in place need to evaluate how Exchange Server can fit into their environment. If AD has not been deployed, the organization or team desi...
