capable of providing detailed status reports on the enclosure’s overall health and recent performancehistory. The embedded software modules:• control enclosure temperatures, communication chips, cooling fan speeds, status lights;• control operation of, manage and integrate the SBOD Fibre Channel embedded switch; and• report data for remote control software to control the enclosures using legacy interfacestandards, such as SCSI Enclosure Services, or SES, and SCSI Accessed Fault TolerantEnclosure, or SAFTE, and emerging interface standards, such as Common Interface Module(CIM) and Storage Management Initiative Specification (SMI-S).Emerging interface standards attempt to add more capability and better define the way devicesbehave and pass communications to each other, by improving device inter-operability, simplifyingnetwork management processes and standardizing and enhancing the device-level information withinhigh-speed storage networks.High-Level User Oriented Programs. The high-level user oriented software programs form a set ofutility tools to manage and configure the data structures stored on the storage subsystems, setting thelevel of security and data protection for each logical data volume within the enclosure. Logical datavolumes are a fixed amount of storage space, usually spread across many disk drives and are treated asindependent physical storage units by the attached host operating systems. A logical data volume canbe shared by many users with programmable access controls to provide a level of data security. Theprograms can run on a wide variety of computer operating systems including Windows, Linux and avariety of other Unix-based systems. The principal features of these programs include:• creating and maintaining logical data volumes within storage subsystems;• establishing permissions and rules to control access to data space within storage subsystems;• editing settings for speed, space, redundancy, fault tolerance and reliability within allocated dataspace within storage subsystems;• creating fast data recovery processes, such as mirrors and snapshots, in the event of software orhardware failures; and• managing and reporting processes for system errors and hardware failures.All these software tools integrate with and complement the expanded management and softwarefeatures within our customer’s overall management system architecture.Storage InfrastructureWe are the leading global independent provider of disk drive production test, servo-track writingequipment and disk cleaning systems. Our Storage Infrastructure products enable our customers to testand produce highly reliable disk drives with greater efficiency and at a lower cost. Over the past fewyears, we have provided production equipment to leading disk drive manufacturers and theircomponent suppliers, including Komag, Maxtor Corp., Seagate Technology and Western Digital. OurStorage Infrastructure products are capable of covering all disk drive form factors, including 3.5 inch,2.5 inch, 1.8 inch, 1.0 inch and 0.85 inch disk drives. These products include:Disk Drive Production Test Systems. We design and manufacture fully automated process testsystems which incorporate mechanical and electronic hardware and software that control the operatingenvironment of disk drives during final qualification testing. This test process isolates any magneticdefects from each drive during an extensive period of testing that can exceed 100 hours for currentgeneration high capacity disk drives. Our test systems can be configured to meet the specificrequirements of individual customers and can be integrated with our customers’ technology. Our test31
