InSpeed^TM Technology

Emulex 公司的 InSpeed 技術, 是一項創新並且經過市場證明的技術. SOC (Switch On a Chip) 已經被廣泛應用在儲存系統之中. 這使得 "完全交換化 Fully Switched 的儲存基礎", 已經是一個應用於下一代存儲系統的事實, 並經由世界級企業儲存廠商如 HP, Fujitsu, ... 等的大量採用; 而 InSpeed 則賦予了 "SBOD" (Switched Bunch of Disks) 以及 "後端交換式架構" (Switched Back-end Architecture) 在市場上的生命.

RAID 應用:
目前磁碟陣列區分為兩種架構: 單一集成 (EMC Symmetric, IBM Shark, HDS Lightning), 和模組架構 (Compaq, Dell, LSI, ...)．而單一集成的架構在以下各方面, 則可充分使用 InSpeed的技術.

	‧	Provide fan out from the host/SAN side connection to the RAID ..... 提供從主機/SAN端連到陣列端的散出.
	‧	Provide connectivity between the front-end and backend modules ..... 提供前端和後端模組之間的連接.
	‧	Provide connectivity from the RAID controllers to the drives ..... 提供陣列控制器到硬碟機之間的連接性.
	‧	Provide drive isolation within attached JBOD cabinets to convert them into SBODs ..... 提供在 JBOD 機箱內硬碟機隔離, 並轉化成創新設計的高速 SBOD. (SBOD 說明)

Emulex acquired Vixel ..... Expands Reach as FC Component Supplier IDC Oct. 2003

This IDC Flash provides insight on Emulex's announced plans to acquire Vixel, a manufacturer of embedded FC switch technology. It also discusses the implications of this acquisition for the FC component market.

S I T U A T I O N O V E R V I E W

On October 8, 2003, Emulex announced its intent to acquire Vixel, a supplier of embedded switch ASICs and subsystems for the storage networking market. Under the terms of the agreement, Emulex will acquire Vixel for a transaction value of approximately $310 million and expects to close on the acquisition in November.

Emulex is the leading provider of FC host bus adapters (the cards used to connect servers, tape systems and some storage arrays to FC networks) with 46.7% market share in 2002, however, the company faces continued pressure from its main competitor, Qlogic (30.8% HBA market share). Combined, Emulex and Qlogic) now control over 75% of the overall FC HBA market and along with JNI (recently purchased by AMCC) account for virtually all of the independent HBA market.

Vixel recently made the transition from FC SAN switch supplier to OEMs to a subsystem and chipset vendor. Along with Qlogic, Vixel is a champion of single chip FC solutions that serve as components within new FC based storage array architectures (e.g., the HP EVA that uses Vixel components) and emerging blade server architectures). Most disk array OEMs use port bypass controller (PBC) chips from Vitesse, Agilent and PMC -Sierra to create the loop interface between FC HDDs. Today, more OEMs are searching for ways to offer embedded switching in their disk array designs to improve overall latency performance (i.e. dedicated pathways to each FC HDD), increase problem isolation (i.e. quickly identify and swap out a failed FC HDD) and advanced monitoring (proactively predict faults in the future).

Vixel's InSpeed embedded storage switching addresses this demand and employs as an internal interconnect solution in storage products from companies such as BlueArc, Fujitsu, HP, Network Appliance, and Xyratex. The company also notes design wins for storage products not yet announced by OEMs.
