AEM-7C

HP 7900A Disk Drive Emulation

The Arraid AEM-7C system provides a new and warranted equipment replacement for aging and refurbished HP 7900A disk drives connected to an HP 13210 Disk Controller. 

The AEM-7C is plug-compatible with the original HP 7900A drive, while using ARRAID's proprietary solid state 'ARRAID Flash Drive' (AFD) to store data.  Internal AEM rotating drives (disk, tape & magneto-optic) can still be supported upon request.

No host system software or controller changes are required to replace a refurbished 7900A drive with the AEM-7C.

Product Details

The AEM-7C provides a complete bridge between the host HP 13210 controller and the AEM's SCSI drives. These drives have been used on HP-1000 computers in a variety of applications. The HP 7900A is a combination fixed platter and removable cartridge drive of 5MB capacity.

While refurbished 7900A replacement drives have limited availability, refurbished drives commonly fail within a few months resulting in system down time. The AEM-7C is provided as new equipment, allowing customers to utilize SCSI drives or ARRAID's proprietary solid state 'ARRAID Flash Drive' (AFD) installed in the AEM-7C, with MTBF of 200,000+ hours and significantly more when using the solid state AFD.

Additional AEM-7C options include disk to disk backup, disk to tape backup, AFD network (backup & restore) mirroring, and multi-volume (provides several HP 7900A disk partitions on a single SCSI media). No refurbished HP 7900A drive can match the reliability, features and customer support provided by choosing the AEM-7C to replace your aging HP 7900A disk drive.

Features

Features and Benefits

  • Replaces aging and refurbished HP 7900A drives with new data storage technology.
  • ARRAID Flash Drive (AFD) option is a Solid State SCSI disk replacing traditional mechanical SCSI drives (DAT, QIC, Tape & Magneto Optical Disk)
  • Additional features such as network backup, mirroring, restore and removable media can be added.
  • The CompactFlash (CF) media in the ARRAID Flash Drive (AFD) is treated exactly the same as the floppy disk media. All drive data is stored on the CF media as if were the original diskette media.
  • AFD network feature option offers LAN network (ethernet-based) back-up and restore capability directly from the AFD using the on board RJ45 Network port. No additional software or register changes are required to the legacy host. Including ARRAIDs FLASH2GUI Software, an optional ethernet support feature for centralised backup and restore capability lessening the reliance to rotate media.  Network option only available on AEM with AFD network drive installed.
  • Additional features such as backup, restore, multi-volume, and removable SCSI media can be added.
  • Easy to install. No hardware or software changes required, other than the drive itself.
  • Can replace or be added to existing drives.
  • Operating system, application and diagnostic software are supported as is.
  • An LED or Alpha-Numeric Operator Panel provides the same controls as the original drive.
    • Minimal Operator training required.
  • Reduced power consumption verses the old drive.
  • High reliability with near zero maintenance required.
    • Greater computer system availability with lower cost of ownership.
  • HP data can be stored to 3.5" solid state ARRAID Flash Drive (AFD) CF media.
    • With disk head alignment no longer an issue, media may be moved from drive to drive without concern for readability.

Mounting for Primary SCSI Storage Device

The legacy disk drive image is stored on the primary SCSI storage device. ARRAID would reccommend our proprietary FPGA based ARRAID Flash Drive (AFD).  AEM-1 Systems may be configured with either fixed or removable drives as the primary storage device. ARRAID FLASH Drive (AFD) are ordered separately. The AFD also offers  backup and restore networking. For **F enclosures, the drive is fixed mounted inside the system enclosure. **RM enclosures include drive bays for removable disk drive modules. The drive bays have a key lock switch for mechanical and electrical interlock.

SCSI Storage Devices

SCSI Storage Devices

An AEM-7C System always requires two SCSI storage devices for split media support. Because of the variety of SCSI products available, all AEM SCSI devices must be defined separately from the AEM.

The suggested choice for the primary storage device is a the solid state Arraid Flash Drive (AFD). The drive may be in a fixed internal mounting or in a removable drive canister.

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-7C. These drives and media have the durability to perform well for many years. MO devices are only available for fixed mounting.

The solid state Arraid Flash Drive (AFD) can be configured as a Disk, Tape or Magneto-Optical drive and has proven successful as the primary storage device in many applications specially when used in a fully cached AEM-7C. Excellent as internal copy/backup devices, these drives and industrial grade CompactFlash (CF) media have the durability to perform well for many years.

Internal Options - Copy/Backup

The AEM-7C 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.

  • NETWORK FEATURE - AFD network feature option offers LAN network (ethernet-based) back-up and restore capability directly from the AFD using the on board RJ45 Network port. No additional software or register changes are required to the legacy host. Includes FLASH2GUI Software which is an optional ethernet support feature for centralised backup and restore capability removing the need to rotate media. Primary data storage is always written to the CF card. Only available on AEM with AFD drive installed.

  • 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 ARRAID Flash drive (AFD)  to a second AFD configured 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 to the solid state ARRAID Flash drive (AFD) configured as a tape drive.

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
