NVMe | 非揮發性記憶體

  • 非揮發性記憶體是什麼?
    NVMe (NVM express) NVM(non-volatile memory)代表非揮發性記憶體,這是固態硬碟(SSD)的常見的快閃記憶體形式。完整說法是非揮發性記憶體主機控制器介面規範(Non-Volatile Memory Host Controller Interface Specification),是邏輯裝置的介面規範,相較於早期用於傳統機械式硬碟規範SATA介面的AHCI,NVMe則是因應PCIe固態硬碟而生的介面規範,提供硬碟更快速的傳輸介面協定。

  • 為何需要?

    早期SSD只能透過PCI Expressc匯流排製造,但需要使用非標準規範的介面,若使用標準化的SSD介面,作業系統只需要一個驅動程式就能使用符合規範的所有SSD。在儲存伺服器或是大量訊算的資料中心中,加速傳輸速度以及盡量減少資訊傳輸的延遲是最重要的事情。

  • 技嘉的特色
    除了消費者市場需求的NVMe固態硬碟,在伺服器市場技嘉的R282-Z92更支援了All Flash Array(全快閃陣列),並全數採用NVMe熱拔插硬碟介面,在第二代AMD EPYC (Rome)平台下,頻寬與傳輸速率分別提升至64GB/s與16GT/s,相較於PCIe Gen 3.0提供翻倍的頻寬/傳輸速率。處理器與周邊配備如加速卡、NVMe介面協定SSD、或高速傳輸網卡可藉由加倍的頻寬提供更高效的資料傳輸。

    What is a Server? A Tech Guide by GIGABYTE
    In the modern age, we enjoy an incredible amount of computing power—not because of any device that we own, but because of the servers we are connected to. They handle all our myriad requests, whether it is to send an email, play a game, or find a restaurant. They are the inventions that make our intrinsically connected age of digital information possible. But what, exactly, is a server? GIGABYTE Technology, an industry leader in high-performance servers, presents our latest Tech Guide. We delve into what a server is, how it works, and what exciting new breakthroughs GIGABYTE has made in the field of server solutions.
