The IBM 7133 Model 600 is a deskside package. The Model 600 provides ease of cabling by requiring no external cabling to complete internal strings of disks. It also improves availability in multi-initiator loops by providing bypass circuits that allow multiple planned or unplanned host outages. The Model 600 provides redundant power to all positions as standard.
Highlights
Improved performance, capacity, serviceability, and availability
Improved fiber optic extension distance
Rack-mount or tower models
Investment protection
Description
Using one of IBM's family of SSA adapters, these 7133 models can be configured for high performance, multihost attachments, or economical RAID 5 data protected storage on Micro Channel or PCI channels of selected RS/6000 and RS/6000 SP processors.
Using the IBM SSA RAID Adapter for PC Servers, a PCCo option, they may be attached to certain IBM PC servers.
Using the IBM SSA RAID Adapter for PC Servers (#4011), they may be attached to certain COMPAQn and H-P servers.
Using the IBM SSA to Sun SBus Interface Controller Card (#4003), they may be attached to certain Sun SPARCstation, SPARCserver and SPARCcenter systems.
Using the IBM 7190-100, SCSI Host to SSA Loop Attachment, they may be attached to a range of Sun and H-P systems.
These IBM 7133 SSA Disk Subsystem models are functionally equivalent and can be populated with up to 16 auto-docking, customer replaceable, SSA disk drive modules. The disk drive modules are available in four different capacities: 1.1GB, 2.2GB, 4.5GB, and 9.1GB. The 9.1GB SSA Disk Drive features are available only in the Models 020 and 600. Four 2.2GB disk drive modules are standard for all models.
However, select features allow these to be replaced by the 4.5GB modules (all models) or the 9.1GB modules (Models 020 and 600 only) at the time of original order. Features are provided to add any combination of supported SSA disk drive modules, up to a maximum of 16, providing up to 145.6GB of disk storage capacity in Models 020 and 600 (using 9.1GB disk drives) or up to 72GB of disk storage capacity in Models 010 and 500 (using 4.5GB disk drives). The power cooling units are auto-docking and customer replaceable.
An SSA Fiber-Optic extender (feature 5500) is available on all models of the 7133. This feature supplies a pair of optical converters that convert electrical SSA signals into optical signals for transmission via customer supplied optical fibers. This feature allows the maximum distance between SSA nodes to be increased from 25 meters to 2400 meters for use in campus type installations. One feature 5500 is equivalent to a single SSA copper cable.
The IBM 7133 SSA Disk Subsystem models are leading-edge, second-generation serial storage subsystems that use industry-standard Serial Storage Architecture (SSA) to deliver outstanding performance and capacity/footprint, improved connectivity and availability, and enhanced attachability.
Product Positioning
The IBM 7133 SSA Disk Subsystem Models 020 and 600 are second-generation serial storage subsystems that significantly exceed the performance and capacity available with directly attached SCSI disk drives. The SSA Four Port adapter can deliver 35MB/sec sustained to the RS/6000 Micro Channel and supports up to 3,000 ops/sec. It can also attach up to 96 SSA disk drive modules, 48 per loop. The enhanced SSA Four Port adapter can be configured with up to eight adapters in up to eight RS/6000 processors or SP nodes within each SSA loop. The SSA RAID adapters can be configured with multiple RAID 5 arrays with global hot spares spread across up to 96 disk drive modules.
In the transaction processing environment, the IBM 7133 SSA Subsystems provide the ideal solution when used as mirrored storage in a "high availability" cluster of RS/6000 server systems for applications that require sustained high performance despite a single failure. If the cost of data protection is more important than high performance, then RAID 5 via the SSA RAID adapters should be considered. The IBM 7135 RAIDiant Array or the IBM 7137 Disk Array Subsystem should be considered for those customers who demand a SCSI attached system.
In engineering/scientific, data-mining, data-warehousing, and decision support applications, the ability to sustain high data rates makes the IBM 7133 SSA Disk Subsystems an attractive solution.
The 7133 provides power and packaging for SSA disk drive modules. The Model 020 is designed to be mounted in a standard 19-inch rack and is four EIA units high. The Model 600 is a standalone unit similar in height to RS/6000 deskside systems.
The Models 020 and 600 provide slots for up to 16 SSA disk drive modules. These 16 disks are grouped together in fours. This is the same as the 7133 Models 010 and 500. The Models 020 and 600 provide circuitry that will automatically connect these groups of disk drives together. The automatic connection are made based on the presence of signals on the external connector. If there are signals present at one connector of a pair of connectors then these connectors will not be connected automatically. If there is not a signal at both of the connectors in a pair then these connectors will be connected automatically.
The 7133 Models 020 and 600 can be populated with three different SSA disk drive modules. The different capacities are 2.2GB, 4.5GB, and 9.1GB. The machine includes four 2.2GB disk drives as standard. These can be replaced by 4.5GB or 9.1GB drives at time of original order.
The 7133 Models 020 and 600 include three auto-docking power/cooling units. These provide redundant power to all sixteen disk drive module positions. These units may also be replaced by the customer.
The 7133 has selectable cable features of up to 25 meters long for attaching to an IBM High Performance 4-Port SSA Adapter in the attaching systems and for connecting to other 7133 subsystems. An SSA Fiber Extender is also available for use with optical fibers up to 2.4KM. The SSA Fiber-Optic Extender uses a 1310nm wavelength laser to drive multimode optical fibers. A minimum of two cables are required to properly install the 7133. More cables may be needed to achieve the desired performance and availability characteristics.
