حد يقدر يقولي

السلام عليكم ياشباب

سوال غبي وزكي فنفس الوقت..للي فاهمين فقط

يعني ايه server >>بمعني اني لما اقول فلان مدير سيرفر ومتخصص صيانته؟؟؟

هل هو عبارة عن جهاز مثلا وعليه ويندوز سيرفر 2003 مثلا ام هو جهاز معين زي الروتر ام اييه؟

وعليكم السلام

السيرفر أخي الكريم عادة المقصود جهاز ذو مواصفات خاصة يمكن تطبيق مجموعة كبيره من الـ Roles عليه
يعني المسألة تنقسم لقسمين
الـ Hardware
والـ Software
مواصفات Hardware خاصة ومتطلبات Software خاصة تختلف عن الـ Workstation

يعني ممكن تطلع على منهاج دوره السيرفر بلس من كومبتيا فتعلم بالتحديد ما المقصود بذلك

السيرفر بيكون جهاز بمواصفات عاليه جدا تختلف عن الاجهزه العاديه ويكون ليه تعامل خاص وفني متخصص له

وعليكم السلام

اتمنى ان الشباب افادوك ويعطيكم العافية جميع

عندي سؤال ذو علاقة مشغلني من فترة ومالقيتله جواب
وهو كيف اختار واحدد مواصفات السيرفر الي احتاجه للشبكة؟
طبعا كل شبكة لها استخداماتها وعدد مستخدمين ولابد ان تكون هناك طريقة لتحديد مواصفات السيرفر المناسب للمكان المناسب
حتى لا نتورط بسيرفر اضعف من اللازم او ندفع الكثير في سيرفر لا نحتاج الا ربع طاقته

أخي الكريم
بالنسبة لسؤالك لو فتحت أي موقع من مواقع شركات الـ HP أو الـ IBM أو غيرها ستجد أن السيرفرات المطروحة مذكور من ضمن مواصفاتها أنها تصلح لـ .......

مثلا https://www-304.ibm.com/jct03004c/bu...cts-_-smallbus
صفحة خاصة للـ
small business product


أو الخاصة بالـ Medium business products
https://www-304.ibm.com/jct03004c/bu..._-med-hardware

وهذه تساعد كثيرا في الاقتراب على الأقل من تحديد مواصفات السيرفرات المطلوبة

وعموما من أصعب الأمور هي تحديد المواصفات المطلوبة والطريقة الوحيده التي يعتمد عليها للأسف هي التجربة العملية

هذا موقع يساعد في عملية تحديد المواصفات
https://e-docs.bea.com/wls/docs81/capplan/capgen.html

وهذا آخر
https://www.sitestream.biz/za/techno...erhardware.asp

ولكنها تبقى إحتمالات وليست مؤكده بالطبع

تقبل التحية
