    remains up and running for years to come.

Background

    The Dell/EMC CX600 is an end-to-end Fibre Channel storage system. The interface to disk drives and to host servers is based on the industry-standard 2 Gigabit/sec Fibre Channel protocol. Fibre Channel storage systems are commonly used both directly attached to servers and in storage area networks (SANs).

    The CX600 is a high-performance and feature rich array that is suitable for the most demanding applications and for storage consolidation of multiple heterogeneous hosts in a cohesive SAN fabric.

Product Description

    The CX600 provides best-of-breed enterprise storage in direct attach or large SAN environments. Storage-based functionality and comprehensive management software offer world-class information protection and streamlined, efficient management. The CX600 is a fully integrated 2 Gigabit storage solution with eight front-end Fibre Channel 2 optical ports and up to 240 2 Gigabit back-end disk drives.

    The features of the CX600 include the following:

    ; Direct connect up to eight servers

    Dell Enterprise Systems Group Page 2 Updated December 2002

    attached to a single CX600 array in a SAN (each server has 2 HBAs

    providing redundant connectivity to the storage array) ; Up to 240 2Gb Fibre Channel disk drives and 35 TB of raw storage

    capacity within a single array (a SAN fabric can house many

    storage arrays)

    ; 2 Gigabit Fibre Channel technology provides up to 200MB/s

    (400MB/s full duplex) throughput - ideal for high bandwidth

    application environments

    ; Eight front-end optical ports per array. Each Storage Processor (SP)

    is equipped with four 2 Gb front-end optical ports, each delivering

    up to 200MB/s Fibre Channel throughput. With the use of

    PowerPath? fail over and load balancing software for multipath

    I/O, users can operate all eight ports simultaneously ; Two full 2Gb bandwidth back-end Fibre Channel loops per SP for

    a total of four 2Gb back-end loops per array

    ; Over 1,300 MB/s sustained throughput and more than 150,000

    cached I/Os per second

Markets/Applications

    The CX600 is an enterprise-class storage system suitable for use in business critical or day-to-day production-level activities that require leading edge performance and scalability with options for business continuance and disaster recovery. The CX600 may be deployed in heterogeneous Windows, NetWare, Linux, and Unix environments and is appropriate for applications in medium-sized businesses to global enterprises. Examples of where the CX600 is a good fit follow:

    ; Business critical applications that require continuous availability

    and disaster recovery, combined with high performance and large

    capacity scaling

    ; Medium to large scale SAN deployments (5 to 60 servers)

    ; Applications that require cost-effective array-based point-in-time-

    copy or cloning

    ; Data center environments where the flexibility of modular storage

    growth is needed

    Direct Attach

    In direct attach configurations, the CX600 provides storage for up to eight directly attached servers or two two-node high-availability clusters. In these configurations, the CX600 has higher availability and allows more distance between server and storage than direct attached SCSI storage

    Dell Enterprise Systems Group Page 8 Updated December 2002

    systems. Also, configuring the CX600 as direct attach storage prepares the server for seamless consolidation into a SAN sometime in the future. Storage Area Networks

    In a SAN environment, the CX600 can actively communicate with up to 128 redundantly connected servers. When used in a SAN, the CX600 offers the following potential benefits over direct-attached storage:

    ; Lower total cost of ownership through simplified management

    and centralized backup

    ; More efficient use of assets through increased storage utilization

    ; Reduced impact to production performance through LAN-free

    backup

    ; Reduced risk of data loss through disaster recovery capabilities

    (i.e., remote mirroring, point-in-time copies and clones)

Typical Applications

    Exchange clusters using MirrorView for disaster recovery.

    The performance and scalability of the CX600 are ideal for high availability clusters running Microsoft Exchange or other messaging software for up to a few thousand users. MirrorView remote mirroring software adds another dimension of data protection to email data by allowing mirroring to other Dell/EMC arrays hundreds of meters or thousands of kilometers away.

    Medium to large sized OLTP databases using SnapView cloning for zero-window, full performance backup.

    The excellent transactional performance of the CX600 coupled with SnapView array-based software is the perfect combination for small to medium sized databases that are active 24x7. Use cloning to create a point-in-time copy of the data, and then back up or analyze the copy while the original data remains in production. Since the cloned data and the original data reside on different disks, the backups and analyses will have minimal performance impact to your database.

    Decision support systems using SnapView snapshots for space efficient zero-window backup.

    The CX600 can also be used for non-critical applications that require a highly scalable, cost effective solution with high performance needs. This is typical of many decision support databases. The CX600 can scale up to 35 TB with 146GB drives providing plenty of capacity for your data. In addition, by using SnapView snapshots, you can back up this large amount of data with zero downtime to your database, and without having to make a full copy.

Video editing and prepress.

    With 1300MB/s of sequential bandwidth, the CX600 is ideally suited to video and prepress applications. The CX600 can directly attach to up to eight high-speed video editing stations. To connect to more servers, simply add a Fibre Channel switch

Features and Benefits

High Availability Hardware

    The modular redundant design of the CX600 helps the system to continue normal operation in the event of a failed power supply, cooling unit, storage processor, or disk drive. All these components are hot pluggable for easy repair with no downtime. Add to this robust design and numerous data integrity checks, and the result is a storage solution that is built to keep information safe…and accessible.

    Cache Vaulting

    The CX600 contains advanced features designed to protect data from corruption or loss due to unanticipated events. For example, when write caching is used, data waiting to be written is stored in volatile memory on the storage processors. With unprotected systems, an unexpected power failure could result in lost cache data. The CX600 protects against such data loss by using a standby power supply (SPS) to keep the array powered long enough to write cache data to disk. Cache data remains protected indefinitely, and is not subject to the vulnerabilities of battery-backed cache found on other storage systems.

    Modular Design

    Specifically designed to create flexibility in the data center, the CX600 makes it easy to get started with a highly available storage infrastructure, then grow as business and applications needs warrant.

    Excellent performance

    With eight front side 2Gbps Fibre Channel ports on the host and four full-bandwidth ports on the drive side, the CX200 has up to 150,000 cached IOPs and sequential performance of up to 1300MB/sec.

    Cache tuning

    All Dell/EMC storage systems have extremely flexible cache tuning capabilities relative to competing modular storage products. This allows cache to be tuned precisely to the load, helping to optimize performance. Non-disruptive upgrade (NDU)

    Non-disruptive upgrade is built into the core software of the CX600. This allows the core code (firmware) to be upgraded on the fly with no
