技術名稱: 超高速長效SSD儲存系統管理技術

技術簡介

SOFA(Software Orchestrated Flash Array)是一個管理快閃記憶體磁碟陣列的軟體,專為透過網路對外提供高效能儲存服務的平台而設計。透過SOFA,雲端資料中心的使用者將能使用到超過1百萬IOPS存取速度的儲存功能。

Abstract

The SOFA (Software Orchestrated Flash Array) is software developed by ITRI to manage flash disk array, and is mainly for platforms providing high-performance storage services via network. With SOFA, cloud data center users will experience the storage function at an access rate of over one-million IOPS.

Technical Specification

Flash Unit:  SSDs Capacity per Node:  5TB~30TB Performance in 4K IOPS per Node:  1M IOPS Data Integrity:  SSD friendly RAID 5  High Random IOPS Feature:  Volume Manager  Block-Level De-duplication  QoS  Global Wear-Leveling  Optimized Network

技術特色

本技術為建構一個系統軟體在一個包含快閃記憶體磁碟陣列的儲存伺服器上,透過網路對外提供存取管理服務,可有效提升存取效能。另一方面,本技術亦支援RAID5用以集合一群磁碟,並突破RAID5效能瓶頸,提升10倍之讀寫效能,透過網路可提供一百萬IOPS的效能。而透過跨磁碟的平均抹寫技術(Global Wear-Leveling),可延長整個磁碟陣列的平均壽命達2倍。 本技術在底層儲存和網路功能的優化之外,還提供虛擬磁碟管理功能,可進行快照備份、虛擬磁碟複製、和自動精簡配置等功能,同時完全不影響存取效能。本技術的虛擬硬碟管理也包含服務品質管理功能,透過合理分配整體資源來確保各個虛擬磁碟空間使用的效能。為了提升儲存空間使用率,本技術還包含了虛擬磁碟空間離線資料壓縮功能,可增加儲存系統的有效空間達到兩倍。
