各位先進好
小弟目前公司有更換L3 switch的需求(原為國產"智慧型L3 Switch")
因內部網路架構相對比較單純
一般L3可做到的網管功能已足夠(實體VLAN切割、routing、ip-mac-binding)
問題差在目前廠內有分接內部光纖兩條(接在L3底下的主L2 switch
換了L3後想提升光纖到新L3管理
且未來打算建構VM環境(兩台互備援VM主機、一台Storage)
SI廠商部份均建議提早規劃支援Backbone 10GbE的L3 Switch
但價格當然是又往上一層
不過未來兩台VM主機與Storage大資料備份應該都是利用離峰時段進行
如不使用10GbE而用1GbE或使用光纖直接聯結呢?
VM伺服器約5個 分成一台3個一台2個 單台硬體可獨立跑5個伺服器沒問題
而公司網路資料吞吐量其實並不大 一天不到1Gb
未來5個VM備份也不到500G
目前屬意型號如下
Cisco 3560G
HP 5500-24G
Juniper EX3200-24p
Netgear GSM7328S
初步可能想以後兩台去選擇 但因經驗十分不足 又不太想完全依SI建議
想求教各位的想法 以未來五年來說是否足夠
而底下的D(ead)-link 年限也差不多(但主管說不能拿來當藉口)
想要換過L3後 逐步整體整合全部都是同廠牌網通設備
因為提到10GbE 使用者端也是要升到giga等級 不過用不多也是無法說服老闆
目前都是100mb加減用
甚至最後仍是變成只有更換L3 Switch
這個可以說服老闆的效益.... 真的只能就數據畫大餅給老闆看嗎
現在會換幾乎都是因為快掛點
有觀念錯誤請不吝指正 在此先謝過各位寶貴的意見!
