| iSCSI 是一個以 IP為基礎的
SAN,
使得企業可維持原來的 Ethernet
基礎架構,
使用已知的知識並帶著儲存設備進了 IP 網路.
iSCSI 被定義為 Internet SCSI
或是 SCSI over IP. 這個協議在
TCP/IP 的協議上,
傳輸著 SCSI
命令組. iSCSI 能讓 SCSI
設備被設定為 IP SAN, 並接合了其他的
SCSI 儲存設備,
好像它們是 "直接存取裝置"
一樣.
而 ATTO iPBridge
系列 (2500, 1500), 就完全符合這樣的需要和條件,
連接各式的 SCSI 設備,
連上 iSCSI SAN 網路.
iSCSI 可以為網站、服務供應者、企業級應用、及其他組織, 提供一個高速、低成本、長距離的儲存方案.
ATTO iPBridge 提供的幾項重要好處:
-
使用現有的IT專業-大多數用戶都具備IP和SCSI知識,這可以減少對新聘雇專業的需要
-
使用現存在SCSI設備分享,而又不需要安裝一個新的網路環境.儲存設備現在可以被帶到IP
Network
-
將已被證明、廣為人知且被了解的IP和SCSI科技,截長補短地結合.這包括了:命令組、路由、服務品質、以及安全機制
-
對管理網路的經理,提供對於將SCSI設備結合到網路上的投資保護
-
改進儲存設備網路的距離,經由IP基礎架構,但存取係經由iSCSI協議

iSCSI is a protocol for IP-based SANs that allows
companies to maintain existing Ethernet infrastructures, use an
existing knowledge base and bring storage to the IP network. Defined as
Internet SCSI, or SCSI over IP this protocol transports SCSI commands
over a TCP/IP protocol. iSCSI allows SCSI devices to be set up on an IP
SAN and engage with other SCSI storage devices as if they were
direct-attached devices.
iSCSI can provide a high-speed, low-cost, long-distance storage
solution for Web sites, service providers, Enterprises, and other
organizations.
ATTO iPBridge offers
important benefits:
-
Uses
existing IT expertise – most users have both IP and SCSI
knowledge already in-house, reducing the need to hire
new talent.
-
Uses
existing stable and familiar infrastructure – enables
sharing of SCSI storage devices without deploying a new
network infrastructure. Storage can now be brought into the IP
network.
-
Leverages
proven, well known, well understood IP and SCSI technology
including command sets, routing, quality
of service and security.
-
Provides
investment protection for IP managers who desire to network
their existing SCSI products together.
-
Improves
storage network distances through IP infrastructure access
using the iSCSI protocol.
