The CalDigit HDPro's unique architecture combines the best in value with the newest technology. The HDPro is compatible with MacPro, G5, Mac OS X Server, Windows, Linux workstations, and other platforms as well.
The CalDigit HDPro features SATA 3Gb/s and up to 16MB cache drives for the speed to meet the demands of the most up-to-date video & content editing software. Each 7200-RPM SATA hard drive connects to a dedicated SATA channel to eliminate bottlenecks and maximize the 3Gb/s native SATA connection. With up to PCIe 8-lane interface to the host, each lane can reach up to 250MB/s. This in turn means that as you add drives, the HDPro scales in both capacity and performance. This powerhouse delivers up to 380MB/s in RAID 5, and up to 400MB/s in RAID 0.
The HDPro not only provides a sustained data rate, but also has the fastest speed in its class yet! The graphs show how well the HDPro is able to handle a real life scenario. One will obtain great results, sustained speeds, and no dropped frames.
Other RAID storage products in the marketplace can playback 10-bit 1080i uncompressed HD footage, but one will most likely experience frame dropping after just 2-3 minutes of playback. The HDPro is a true editing solution that maintains its data rates during editing and playback without dropping frames!
Each HDPro holds up to 8 drive modules in a Tower or 2U affordable rack mount package. The swappable functionality of the HDPro allows users to upgrade the drive capacity as needed, while remaining very simple to configure and set up. There is no capacity limitation to any single chassis.
When you need large storage for your HD projects, large media files, database, photos, and/or images - the HDPro is your best storage solution.
With single parity in RAID 5 mode, the HDPro features an advanced distributed parity algorithm. This accesses data and parity blocks across all drives in the disk array. To improve the write and read performance, RAID 5 removes the limitation that the dedicated parity drive represents in RAID 3.
When configured in RAID 6 mode, fault tolerance is maintained by the world class CalDigit RAID engine ensuring that the parity information for any given block of data is placed on TWO drives separate from those used to store the data itself. Such double protection is to protect your valuable data even if two drives fail.
With CalDigit's uniquely engineered Active Sustained Transfer Technology (ASTT), the performance of your HDPro is always kept in check. Highs (or peaks) & lows (or drops) during the data transferring are equalized by ASTT.
ASTT optimizes the best transfer size and timing between RAID controller cache and the host machine. This eliminates performance drops and maximizes the sustained data rate. ASTT technology also helps to maintain a continuously smooth transfer rate over the whole capacity of the RAID.
24 hours a day/ 7 days a week/ 365 days a year, the CalDigit HDPro is designed for nonstop operation with uninterrupted access to your critical data. All active components are modular design and can be replaced quickly with a minimum amount of downtime.
The HDPro uses load-balancing power management to spread the workload between two power supplies for optimal power consumption. The load balancing method manages the selection of an appropriate power supply. This enables the HDPro to continue working in the event of one power supply failure.
Redundant hot-swappable power supplies (Optional for HDPro Tower), fan, and drive modules enable the system to keep running even if one module fails. All active components are modular and designed to be switched in and out in seconds - No tools needed, no interruption of service.
Each HDPro uses an environment monitor processor to monitor and manage all aspects of the system including: hard drives, RAID set, controller, controller cache, fan, temperature, power supply, and enclosure conditions. In the event of a problem, the HDPro will send out an E-mail notification.
The HDPro RAID Admin utility, RAID Shield, can build multiple RAID sets on the fly with variety of settings, cache sizes, capacities, slices, logical unit numbers, RAID levels...etc, enabling you to bring storage online with no waiting for initialization. Instantly, you can have RAID storage meeting your requirement. Since this utility is written entirely based on TCP/IP architecture, you can monitor and manage your RAID storage from anywhere on the Intranet. Once you've used this utility to set up your RAID sets, the RAID Admin utility provides at-a-glance status for monitoring subsystems for multiple local and remote HDPro systems.
Monitoring the activities of your HDPro is easy with CalDigit's intuitive LED visual feedback, which allows you to easily monitor your RAID's status with indicator lights on the front panel.
There is an audible signal to signal any system, controller, and drive failure.
Unlike Fibre Channel, SCSI, FireWire and eSATA RAID storage, CalDigit HDPro is a native PCI Express using a direct connection to the computers bridge chip and memory system combined with high link speeds. This direct link eliminates latency introduced by the conversion of other interfaces to PCI Express and provides superior bandwidth, availability and deployment flexibility over earlier-generation SCSI and Fibre Channel technology.
PCI Express includes error correction, and adapts to the speed of the slot automatically. CalDigit HDPro features PCIe x4 or x8 lane, 250MB/s per lane, bandwidth for ultrafast data transport between the storage system and the host computer. It also includes a high quality Molex PCI Express cable and special electronics, to ensure a stable and high quality connection from the storage to the computer. This means you get both superb speeds and reliable bandwidth for high-speed data transfer.
HDPro's cable has a substantial connection for added strength and long-term protection against any potential object that might disrupt workflow. The secure latch will prevent it from coming off easily.
Built-in Integrated Intel XScale core to accelerate RAID engine.
With multiple RAID levels support and an integrated Intel XScale core to accelerate RAID performance, the CalDigit HDPro provides a simple solution for professionals looking to increase performance and add protection to storage.
Due to HDPro's sustained and high speed data transfer rate, the size of controller cache can act as a bottleneck. For example, the video playback does not keep up with your movements on the timeline, and lag behind. Larger cache size keeps up with you as you edit and buffer the video files. For the critical application, you can increase HDPro controller cache up to 2GB.
HDPro is a flexible, open, remarkably scalable, and highly available RAID storage solution with virtually unlimited storage capabilities. It uses CalDigit's advanced PCI Express architecture that enables it's pay-as-you-grow scalability.
As additional higher storage capacity becomes necessary with the growth of your media files; more HDPros can be attached and configured easily in the field without downtime. Simply done by adding a few key components - CalDigit PCIe switch and two-port PCIe card - these products will achieve your goals efficiently and cost effectively.
Each switch can connect upto 7x HDPros, one host and one switch. Using hierarchical CalDigit PCI Express switch, you can have (in theory) unlimited storage pool across disk available to your media and database.

I just wanted to say thanks for taking the time to CALL me after you were unable to reach me via e-mail yesterday. I am glad that you contacted me when you discovered that the mouse that I ordered was no longer available in the color that I wanted and am very impressed with the personal approach that you and PowerMax have taken even though PowerMax is an online vendor. Even though I was not able to purchase from PowerMax on this occasion, I will certainly buy from you in the future. It's nice to see that there are still people out there that care about their customers.
