現在的Optane memory確實因為容量太小而顯得雞肋
但是對Intel來講,Optane的真正戰場是在Optane DIMMs上。現在一條DDR4 32GB萬把塊,
插滿八條最大也才256GB。
但是在Optane DIMM,單條可以512GB,或許不用插滿八條,插個4條就2TB了。如果還能混
插一般的DDR4,我認為伺服器的使用可能會很夯。
至於一般使用者,SSD夠便宜了,480GB都快變地攤價,2k以內的也不是沒有的買,不需要
特別鍾愛Optane。

昨天只是根據印象先來一篇,現在補點資訊
從這個網頁的介紹可以知道幾點:
1.Optane DIMMs要等到支援的處理器,也就說Cascade lake上市。但是目前Optane DIMM
已經出貨給Google了。
2.單顆處理器支援到3TB的記憶體,雙處理器伺服器可以支援到6TB。
3.Optane DIMMs為DDR4插糟,且支援跟一般的( DRAM )DDR4混插。
4.Intel主打相同容量下,價格遠比DRAM便宜。
5.為了更好的支援Optane DIMMs,Intel已經發佈開源軟體嘭ersistent Memory Developm
ent Kit (PMDK) 。
目前的Opane DIMMs是第一代
