[Windows 10] Resilient File System ReFS

How to use Resilient File System (ReFS) on Windows 10

ReFS已經成為Windows 10既內置功能, 係Microsoft新開發(Windows 8時)既File System, 兼容NTFS,  但就解除了一些NTFS既限制, 改善和優化大量資料取存如Data Center.

上面條URL有教點樣係W10, 開Virtual Drives來試玩ReFS!

其實Microsoft係雲端領域已經攀升至二佬, 係佢重要的收入來源, 而且仲係年年高增長, 現任CEO就係升職前擔任雲端服務主管!
佢既Data Center都有需要特別優化既File System!

以前D跨國公司, 唔同地區開公司, 都要係當地買servers, 請system admins/operators, 自從D雲端服務愈來愈強, server都唔洗買, system admin/operator又可以請少幾個.  D靠製做Server既公司就慘豬!

-Resiliency to data corruption with a built-in mechanism with salvage that offers maximum volume availability.

-Data and metadata integrity.

-Large volume support up to 1 yobibyte (that's 1.2 trillion terabytes).

-Maximum folder size of 18.4 × 10^18.

-Maximum file size of 16 exabytes (16 million terabytes).

-Improves data striping performance and redundancy for fault tolerance.

-Disk scrubbing (error correction) for protection against latent disk errors.

-Shared storage pools across computers to provide additional failure tolerance and load balancing.

-Data stored on disks using ReFS can be easily accessed using the same mechanism employed by any operating system that can access files on NTFS volumes.

    連MS 自家既data center 都會跳過D ODM, 自己直接同D 零件商deal. 以後好多Mid-Low level 既Op 會無晒. 不過HK 行得咁慢, D 老細難接受無左on premise 咁virtual. 或者仲有三數年貨者坤下既.

依家好多野想on premise都已經冇la......

    但你先要過負責俾錢個人個關呢.....
其實從arch 角度loading 黎睇, 放晒出街的確係幾爽.  但都要做好contingency.

講開就順便吹下水, 之前睇到一篇網上的報導關於FPGA chip!

再search返, 可能係這個post:
Microsoft is retooling its datacenters with FPGA chips

Microsoft's use of programmable chips called field-programmable gate arrays (FPGAs) in its data centers. These programmable chips are faster and less power-hungry, helping Microsoft to stay competitive against its competitors in the cloud.

expects FPGAs to power all Microsoft online services in the future, and as of today the programmable chips are already helping Bing to improve its results thanks to artificial intelligence.

Additionally, one Microsoft employee told Wired that Office 365 will soon use FPGAs to deliver encryption, compression and machine learning to all of its users.


由於Microsoft大量使用FPGA chips(主要係Altera共應)係佢地既DataCenters, Intel見MS咁玩法, 就收購了Altera, 亦會大力發展FPGA chips.

話唔定有一日, FPGA chip會發展到民用, 部PC或Device, 除了update firmware, OS, softwares, apps等等, 仲要update埋粒CPU既線路點走法!

可能MS最叻programming那批人, 現在係寫緊FPGA個線路走法!

However, reprogramming the Silicon is not an easy task. Jim Larus, another Microsoft researcher who worked on early FPGAs prototypes explained: “That is just horrible, much worse than programming software. Much more difficult to write. Much more difficult to get correct.”

MS 成日都有好野益人. 點解佢唔自己收左架廠呢? 反而彈張好牌俾intel 上.

software giant 始終都係software giant.

香港D老細唔肯轉野, 而且仲係諗住on premise可以買一次就用十年............
所以在比錢個人的角度睇......放上雲 = 交租 = 幫人供樓 = 浪費, 比左N咁多錢都冇舊磚渣手....(完全無視"交租"所帶來的生產力)

    tangible asset 丫嗎. 條數可以谷大D囉. 攞買樓有野揸手既concept 去睇廿一世紀既business development, 所以咪只可以做到賣魚蛋scale 囉. 人地就真係帶黎既revolutionary change. HK 就算有, 都要係同粒魚蛋有關.

況今latest technology 閒閒地on premise installation 都幾十萬先有野睇. 一係無budget 試. 一係買左番黎放係度吽虫. 仲未計特登請人番黎做. 有得租, 幾千銀貨仔小試牛刀. 有效果先再問上邊funding 搞大佢其實係同cost efficient

呢個諗法係香港人來講, 特別無說服力.
需知道, 今日想水你過雲, 緊係平價租比你.
他日人人上雲, 仲平?  

日後你要用佢個 infrastructure, 佢收幾錢你都要比, 咁佢會點做?  
今日業主就睇你盤數, 你賺多$10, 佢加$9租, 你賺多$100, 佢加$99租.
商戶就點做都係賺 $1.

當年啲公司用得 windows 做 os, ms 千方百計要大家由買轉租, 你當 ms 傻咩?
以前買套 office, $2xxx 用幾多年都得 (單頭買).   而家 office 要收 $5xx 一年.  
計一計, 差唔多用5年就打和. 好似4,5年出新版, 轉新版差唔多價錢, 你唔轉其他人都轉啦. 多多理由轉買為租.
但唔好忘記, 公司仲可以選唔轉, 一個 office 2000 用足10年. 貴就唔轉, 遲啲轉, 成本仲可以控制.

但到時上晒網, $5xx 一年又要用, $5xx 一個月都要用, 唔用就開唔到 file.  啲公司仲可以點?  呢啲風險小朋友都識啦.

MS 同各大軟件廠, 而家做法係將 life cycle 縮短, 務求做到租可以時時轉新版, (後生仔, 好學, 有新野想用新. 但公司老屎忽未必一定想轉喎).
更甚者, 軟縮短 cycle 都唔夠, 要你轉 hw 就便 software 都轉埋.
2者取其短, 迫你盡快轉用受制嘅版本, 然後佢可予取予攜, 到日後 xp, win 7 , win 8 甚至 win 10 呢類 "買左就有權用到盡" 嘅軟件消失晒.  全世界都要租用, 佢就可以步步高升了.

你用得佢舊雲, 仲可以走得去邊?

    你提呢個現像, 好似mobile ecosystem 更嚴重喎. 哈哈.
但多人用左會變貴, 你指假設得一間provider?! 咁多competitor 個價正常係愈做愈平.
你唔見google 踩入黎, 間間再向下調.
減到咁上下又加番價, 通常係經一段cut throat 之後既M&A 就會加番價. 但只要有肉食就會有competitor.
君不見大家既mobile fee, broadband fee 咁多年黎, 雖有上有落. 但average out 都無乜點變.
唔講consumer base, 租VPS, data center D 價咪又係咁上下.

再者, 個infra OUT左出去, 你計落好似好重皮. 但慳左既人手條數都唔少野.
當1個Operator 係2 皮一個月. 咁上下既infra 要2個睇. 唔使炒得. 1個月慳左4皮. 1 年就48萬了.
