`
`Modular 5.25" Full-height Ultra SCSI
`
`CMD Viper-II™ RAID Controller
`
`CMD’s CRD-5500 Ultra SCSI to Ultra SCSI
`RAID controller is the industry’s best solution
`for building high perfor-
`mance, high availability,
`fault-tolerant Ultra SCSI
`disk array subsystems.
`CMD’s years of
`experience as
`an industry
`leader in high
`performance,
`advanced technology RAID con-
`trollers and SCSI host adapters for UNIX,
`midrange and PC systems has given CMD
`unmatched insight in designing a second-generation
`disk array controller solution that allows OEMs,
`resellers, and systems integrators to build the best
`fault-tolerant RAID subsystems available today.
`
`Key B e n e f i t s
`The CRD-5500 was designed to satisfy the
`most demanding requirements of today’s sophis-
`ticated RAID user. By giving you high perfor-
`mance in every application, there is no need to
`compromise reliability or data integrity.The keys
`to the CRD-5500’s outstanding performance are
`
`(cid:20)(cid:3)(cid:82)(cid:73)(cid:3)(cid:23)
`
`CMD designed proprietary ASIC components, as
`well as innovative caching and RAID algorithms. In
`addition, the CRD-5500’s modular design allows
`you to quickly and easily configure an optimal
`RAID subsystem simply by installing individual
`Ultra SCSI/ Wide/Single-Ended, Ultra
`SCSI/Wide/Low Voltage Differential (LVD), Ultra
`SCSI/Wide/Differential, or Fast SCSI interface
`modules and up to 512 MB of data cache using
`industry-standard SIMM modules. CMD’s
`active/active failover capability provides unmatched
`levels of fault-tolerance and I/O load balancing.

`
`The CRD-5500’s scalable architecture provides the ultimate in configuration flexibility and performance,
`allowing you to easily upgrade or enhance the capabilities of your RAID peripheral investment!
`
`CMD’s Flexible RAID Architecture
`Scalable Performance, Features, & Configuration
`
`CMD designed the CRD-5500 with the OEM and reseller in mind.The CRD-5500’s scalable architecture was designed to allow you to
`configure a RAID storage solution for every application, from entry-level imaging workstations to fully fault-tolerant, high capacity OLTP and
`video-on-demand servers. Unlike other RAID controllers, CMD’s unique and modular design uses individual SCSI interface modules that
`allow the user to increase performance and expand subsystem capabilities by simply adding modules.A total of up to nine SCSI modules may
`be installed, with up to four configured for host and up to eight configured for disk use. CMD offers Fast SCSI/Single-Ended (CRD-5530),
`Ultra SCSI/Wide/Low Voltage Differential (LVD) (CRD-5580), Ultra SCSI/Wide/Single-Ended (CRD-5540), and Ultra SCSI/Wide/Differential
`(CRD-5560) SCSI option modules, which can be used as host or drive channels (CRD-5530 is for disk use only). Only CMD allows you to
`easily add new interfaces or more powerful modules as they become available, protecting your valuable storage investment!
`
`Unmatched Performance & Reliability
`CMD’s CRD-5500 provides unequaled performance! To meet the performance requirements of tomorrow’s high speed serial interfaces,
`CMD designed the CRD-5500 to use the MIPS R3000 family of 32-bit RISC processors and proprietary CMD custom ASIC logic components.
`Each 5500 includes separate ASICs for RAID (Exclusive OR), DRAM management (fast page mode DRAM control), CPU-I/O (CPU support
`logic), and DMA (high speed data path management).An internal 80 MB/sec, 36-bit (32 data and 4 parity) data bus allows for ultimate perfor-
`mance.
`Install up to four industry-standard, 72-pin SIMM modules to provide a total of up
`to 512 MB of (user-selectable) write-back or write-through cache.To provide guaran-
`teed data integrity, the CRD-5500 includes a built-in battery charger and monitoring
`circuit that supports an external 6.6VDC sealed lead-acid type battery (not included)
`for cache power back-up and a UPS status input that allows the CRD-5500 to switch
`from write-back to write-through data caching should the UPS’s primary power fail. In
`either case, the CRD-5500’s intelligent power management circuitry assures cached
`data integrity during extended power blackouts or enclosure power supply failure.
`
`CMD’s proprietary RAID chipset is the key to the CRD-5500’s
`advanced features and incredible performance. Four separate
`ASICs for RAID (Exclusive OR), cache control, CPU-I/O
`(CPU support logic), and DMA (high speed internal data bus)
`functions support the industry’s most advanced architecture.

`
`
`
`The Maximum In Performance & Data Availability
`
`CMD provides almost unlimited configuration options! Up to nine SCSI modules can be installed
`for host (up to four) or disk (up to eight) use, supporting up to 120 disk drives and 32 logical devices (LUNs). RAID
`sets may be configured in any orientation and freely moved within the CRD-5500’s SCSI disk channels.
`
`Unlimited Configuration Flexibility
`The CRD-5500 allows almost unlimited configuration flexibility! Each CRD-5500 supports up to 32 logical devices (RAID sets or JBOD
`disks) as separate SCSI Logical Unit Numbers (LUNs). Logical devices can be mapped to individual host channels as shared or non-shared,
`with a LUN number unique to a specific host bus. RAID sets can be configured in any orientation and can consist of one to 56 drives,
`depending on RAID level and other options selected. Partitioning is supported on a per-LUN basis (up to 16 per RAID set), as well as
`write-through or write-back caching. Global (floating) spare disks and stand-alone (JBOD) disk drives are also supported. In addition, the
`CRD-5500’s dynamic reconfiguration capability allows individual disk drives and RAID sets to be removed and re-installed in any location.
`High performance, fault tolerant RAID subsystems can be configured using two CRD-5500s in a redundant configuration (depending on
`host platform and operating system capabilities).
`
`Choose RAID 0, 1, 0+1, 4, or 5
`To Optimize Your Performance & Data Availability
`
`The CRD-5500 gives you the option of selecting the RAID level that best suits your application’s unique requirements. Each RAID set can
`be formatted as RAID 0 (for high throughput without data protection), RAID 1 (disk mirroring for small capacity applications), RAID 0+1
`(mirrored RAID 0 arrays), RAID 4 (for large file size, high throughput applications) or RAID 5 (for small file applications, such as OLTP or
`database servers). Regardless of the RAID level you choose, the CRD-5500’s exclusive RPM (RAID Performance Monitor) algorithms provide
`information on cache hit rate, stripe size, and I/Os per second that allow you to fine-tune your RAID subsystem for maximum performance.
`
`Other CRD-5500 Key Features Include:
`• Global spare disk with dynamic rebuild. Multiple disks can be configured as hot or warm
`• Supports mixed disk drive vendors and capacities, even within the same RAID set
`• Front panel LCD display, I/O channel LEDs and audible alarm for reporting critical failures
`• Comprehensive statistics and debug utility (via terminal) for optimizing subsystem performance
`• Redundant controller support option for building true Fault Tolerant subsystem configurations
`• RS-232 serial terminal interface for configuration and monitoring
`• Remote Terminal Services’ (RTS) interface option
`• Separate termination power input for SCSI disk drives
