有幾個方法可以達到，最快的方法之一： 討論主題：【重裝上陣】資戰每秒4GB火線4通道陣列 [將此主題加入筆記簿] 主題發表人： purelove [發表於 2006/12/31 14:25 ] 回應 | 轉寄此篇 原本MAC 熱愛的Fibre-Channel 下半年WIN 平台拜PCI成熟， 目前已有PCI Express x8、PCI-X產品量化生產線穩定產品， 並且有2GB、4GB、單通道- 4通道介面可供選擇！(有效距離30呎) 理論值可以提供2000MB/s 陣列速度，實戰可以提供800-1600MB/s！ (只要8顆7.2K轉 SATA_2+ RAID_0) 準備好座穩抓好方向盤享受【大容量DDR記憶體等速的硬碟】。 (2006 copyright ATTO)  ● The Celerity FC-44ES 4 Gb Fibre-Channel Quad-Channel PCI Express Host Adapter from ATTO is a PCI Express expansion card that allows you to connect 4 Fibre-Channel devices to your computer. The card features quad 4 Gb Fibre-Channel ports with optical connectors, but it is fully compatible with 2 Gb and 1 Gb Fibre-Channel devices. The card supports speeds of up to 800 MB/sec per channel, making this an excellent solution for your high-speed data access needs. Key Features • Fibre-Channel Connection The 4 Gb Fibre-Channel connection translates into data transfer rates of up to 800 MB/sec. This gives you enough bandwidth to work with such data intensive applications as video editing, music production and database development. • Advanced Fibre-Channel Functions The controller supports many advanced Fibre-Channel functions including the SNIA HBA API and Windows FDMI and WMI. It also supports Target and Initiator modes and is fully backwards compatible with 2 Gb and 1 Gb Fibre-Channel devices. • ADS Technology The Advanced Data Streaming (ADS) Technology is designed to allow for controlled acceleration of data transfers, allowing you to move large amounts of data faster and more efficiently. This gives you the I/O performance you need to work with transfer intensive applications. ● Interface Protocol 4 Gb Fibre Channel Host Connection Type PCI Express x8 Data Transfer Rate Up to 800 MB/sec per channel Cache Memory Not Specified by Manufacturer Channels 4 Device Support 4 Gb, 2 Gb and 1 Gb Fibre-Channel FC Topology Direct Fabric, Arbitrated Loop, Point-to-Point Transfer Class Class 3 Hot Swap Support Yes Connectors 4x Pluggable Optical LC SFP Transceivers Maximum Cable Length 1640 '' (500 m) at 1 Gb 984'' (300 m) at 2 Gb 492'' (150 m) at 4 Gb Raid Supported Software RAID Supported Included No Drivers Supported Windows Server 2003, XP, 2000; Red Hat Linux 2.4 and 2.6; SUSE Linux 2.6; Mac OS X 10.4; Novell Netware 6.5; Solaris 9 and 10; FreeBSD; Fedora Included Yes System Requirements Mac Mac OS X 10.4.x or greater Windows Windows Server 2003, Windows 2000, Windows XP Hardware Available PCI Express x8 Slot Power 12 V at 2.1 A max 3.3 V at 3.0 A max Environmental Requirements Operating Temperature: 32-113° F (0-45° C) Humidity: 5-95%, non-condensing Storage Temperature: -40-157° F (-40-70° C) Humidity: 5-95%, non-condensing

磁碟陣列的上限是在【介面】，單顆硬碟速度的變因不一定絕對！ 因為緩衝資料會在CACHE裡，CACHE的穩定上限大約是2GB/s每秒， 剩下就是【線材】可以跑多快會【穩定】，fibre也大約是2GB/s會穩。 (4 channel)
