SCSI Storage Devices
An AEM-6C System always requires a primary SCSI storage device and may require one or more additional devices for split media support or internal copy/backup. Because of the variety of SCSI products available, all AEM SCSI devices must be defined separately from the AEM.
Due to the relatively small capacity of emulated drives, their slow transfer rate, and need for a large number of removable cartridges, Magneto-Optical drives have proven to be an excellent choice for use in the AEM-6C. Also great as internal copy/backup devices, these drives and media have the durability to perform well for many years. MO devices are only available for fixed mounting.
The primary storage device may also be a hard drive. The drive may be in a fixed internal mounting or in a removable drive canister.
Note: As of December 2005, 50 pin drive models (DRV-45 and DRV-45R) have been discontinued as the 50 pin drive bays and canisters to support them are no longer available. All current AEM models use 80 pin hard drives as primary storage devices in both fixed and removable enclosures (DRV-45 and DRVM-45R). Drives are not interchangeable. Existing AEMs may be retrofit to support the 80 pin drives. Contact your Arraid Representative for details.
Internal Options - Copy/Backup
The AEM-6C supports a number of internal options that provide the capability to copy the legacy disk image from the primary SCSI device to a second SCSI device. The copying takes place internally to the AEM, and is independent of the Customer's operating software or hardware. Usually used for system backup, these options can greatly reduce or eliminate the need for a magnetic tape drive on the system.
- Disk-to-Disk Off-Line Copy - Allows the User to clone emulated disk images from the primary SCSI device to a second, usually identical, SCSI device for backup purposes.
- Disk-to-Cartridge Media Disk Off-line Copy - Allows the User to clone emulated disk images from the primary SCSI device to a second SCSI device, such as an MO cartridge disk, for backup or distribution of media among similar systems.
- Disk-to-Tape Off-line Backup - Allows the User to create a backup copy of the emulated disk image on DAT.
Other Internal Options
- Fixed/Removable Emulation - Emulates those drives where the drive capacity is split between fixed platters and a removable cartridge.
- Multi-Volume Support - Allows storage of multiple legacy disk images on one SCSI device.
- Interface Connectors - Several styles of interface connectors are available and should be ordered to match the existing cabling.
External Options
- Interface Cables
- Mounting Shelf
