目前已使用容量約5T
一年增加1T的速度成長
預估十年來看
(我認為3C產品十年應該是該汰換更新)
所以大約需要至少15T
鎖定CP值最高的
HC530 14TB與 HC320 8TB來做搭配
使用raid 5來評估
目前有兩個選擇
1.DS920+ 14TBx3 (實際容量28TB)
17400+7000x3=38400
2.DS1520+ 8TBx4 (實際容量24TB)
21600+4000x4=37600
兩個方案價格差不多來比較:
1.方案優點是容量較為充裕
但顆數少風險較大
2.方案反之容量較少,
但顆數多風險相對低一點
不過還有差異還有
14TB使用氦氣vs 8TB使用空氣
14TB應該安全一點
如同一開始所說 我目前抓十年的使用期限
兩方案都大於20TB這使用應該都沒問題
就容量來說
兩個方案都還預留一個擴充槽來預防
再差我還可以擴充DX517但這經濟效益太差
XD
請問各位我還有什麼沒考量的
以及怎麼搭配比較合理
