| CalDigit RAID Card Specifications |
| Now, with the release of CalDigit's RAID card you have the ultimate in reliable support for RAID 0, 1, 5, 6, 50, 60 and JBOD, with the specs you want, up to 500MB/sec. at RAID 5, with 16 drives connected. The CalDigit RAID card utilizes a dedicated, internal drive channel within your existing system. It instantly expands your present system giving you high availability access and secure storage for all your databases and large media files, with up to 16TB capacity. This unique, cross-platform technology is compatible with MAC OS X, Windows and Linux workstations. All CalDigit products support a variety of software applications and have been validated by Matrox Video Group, Blackmagic Design and Media 100. Room to Grow CalDigit's RAID Card is a 100% hardware disk controller that comes with its own, independent CPU. This uses less CPU cycles and power than a software solution and leaves your workstation's CPU free to do what it has been designed for - running your applications. Software RAIDs use your workstation's CPU. This takes away processing power from other applications and slows your whole system down. Hardware RAID gives you the ultimate in protection from OS corruption or crashes while a software application gives no protection at all. Software RAIDs are also generally more complicated to run and configure. The CalDigit RAID card is straightforward and simple to use and includes additional features for optimizing the performance of your system. If high speed performance is your only concern set your RAID level to 0. At RAID 1 your data is mirrored on to two drives. This gives you the best protection in a multi-user system. The read performance is improved since either disk can be read at the same time, while the write function remains the same as single disk storage. With a sustained speed of up to 500 MB/sec. at RAID 5, the CalDigit RAID card is hard to beat. RAID 5 is best suited for multi-user systems in which performance is not so critical and that do few write operations. At RAID 6 your system can sustain two drive failures without data loss, giving you dual parity protection. This offers extremely high fault and drive-failure tolerance and rapid speed availability. And if that isn't enough, the CalDigit RAID card can also be set to levels 50, 60 and JBOD. Due to the RAID card's compatibility with Mac, Windows and Linux workstations and its expandability up to 16 drives it offers a remarkable flexibility. As your workloads grow and your storage requirements increase the RAID card allows you to add up additional storage units as they are needed This gives you "pay-as-you-grow" scalability as your business expands. You no longer need to be baffled by commands and window layouts that are hard to understand. Managing your drives, running regular performance checks and monitoring your system have never been more straightforward. The CalDigit RAID card uses an environment monitor processor to run all aspects of the system. Our Raid Shield allows you to check your hard drive, add or remove the controller, monitor the controller cache, maintain enclosure conditions, fan, temperature and power supply. You can configure and manage the RAID arrays and fix problems with a simple click of the mouse. In the event of any errors, alerts or changes to the RAID array an e-mail notification is sent to you immediately. It optimizes low power consumption, maximizes performance, accelerates data processing and adds protection to storage. Active Sustained Transfer Technology (ASTT) With ASTT, the performance of your RAID card is always kept in check. Any highs (peaks) and lows (drops) during data transference are equalized by our Active Sustained Transfer Technology. It optimizes the best transfer size and timing between the RAID controller cache and the host machine. This eliminates performance drops and maximizes the sustained data rate. ASTT also helps to maintain a continuously smooth transfer rate over the whole capacity of the RAID. In the event of a power failure the RAID card will automatically switch over to the battery back-up and complete any unfinished tasks. This gives you an added insurance that no data will be lost or stuck between your hard drive and the cache memory. *Battery backup is optional. The built-in 256MB cache keeps up with you as you edit and buffers your video files. Our RAID card also comes with built-in ECC Protection (error correction coding). Any memory errors are automatically detected and corrected. This limitation gives Window Users no other alternative but to install software RAID. This defeats the purpose of using an external, hardware RAID storage system. Now you can utilize the full volume of RAID Card storage in to one single volume to store your data. And with our RAID Shield configuring your system is effortless and easy to execute.

| CalDigit RAID Card Frequently-Asked Questions |
1. HOW DO I TERMINATE A SCSI BUS? When a SCSI controller issues a command to one of the devices on the SCSI bus, it does not expect to have that command come back to it. Instead, it expects to hear just the response from the drive it issued a command to. Properly terminating the SCSI bus prevents signal reflection on the cables, essentially absorbing commands when they reach the end of the cable. On an improperly terminated SCSI bus, it is common to have the controller software issue error messages caused by unexpected activities on the bus or to experience complete failure of the bus. The "golden" rule for SCSI termination is that each end of a SCSI bus must be terminated and no terminator can exist anywhere in between these ends. When you add or remove drives from a SCSI bus, you must comply with this rule. Each SCSI bus starts with a controller. The controller is terminated. Even if there are no drives attached to it, the controller can still issue commands to search for drives without having those commands reflect. Typically, you will add at least one SCSI drive to the bus. You will do so by connecting a ribbon cable from the controller to the drive. Note that one end of the ribbon must plug into the controller and the other end must plug into the drive. In this case, the drive must also be terminated so that both ends of the bus are terminated according to the rule! If you then add additional drives, you can install the drives anywhere along the cable, providing only the drive on the end is terminated. The termination rule gets complicated when you try to add both internal and external SCSI drives to a system. Since the rule states that the ends of the SCSI bus must be terminated, obviously the drive connected to the end of the internal cable must be terminated and the drive connected to the end of the external cable must be terminated. Unfortunately, this leaves the controller somewhere in the middle of the bus and it too is terminated. If the controller does not provide automatic termination enable/disable, you must manually disable termination on the SCSI controller. Note that termination violations might sometimes appear to work. However, it is better to be safe than sorry. Follow the rule! Terminating a drive usually involves installing or removing a jumper on the drive. Check your drive manual for this jumper setting. If the drive does not provide built-in termination, you can purchase a stand-alone terminator. Terminators are available to plug into most SCSI connectors and come in a whole host of shapes and sizes so get the one designed for your application. Note that most new SCSI drives do not provide a built-in terminator and termination is provide by a separate terminator plugged into the end of the SCSI cable.
