OVERVIEW |
|
SuperVolume (previously known as SuperSpeed) is a sophisticated yet elegant solution to the disk I/O bottleneck. Employing a patented hybrid cache, it mirrors an entire disk partition or volume in RAM. In essence, a cache is created in RAM which maintains a one-to-one relationship with its associated partition or volume. All data residing in the partition or volume is also present in the cache. The file system, drive letter, and all other attributes of the original partition or volume are preserved.

How does SuperVolume accelerate a program? |
|
If a program needs lots of data (e.g. images for a video game) it's much faster to have it come from RAM than from disk. When running a program with data on a SuperVolume partition or volume, the disk-related delays and ‘hiccups’ normally experienced disappear! The program is no longer hampered by slow disk access, instead it can run smoothly at memory speed. In addition, when a program needs to save information it will first be saved to RAM. Then, in the background, SuperVolume will save these changes back to the physical disk for safekeeping. Therefore the program's disk I/O problem is greatly reduced, if not eliminated! |

SuperVolume supports write-through and write-deferred modes. In write-through mode, writes are immediately sent to the cache and to the disk. This eliminates the possibility of data loss in SuperVolume due to a system crash or power failure. In write-deferred mode, writes are immediately sent to the cache only, and then to the disk at a later time. This mode of operation results in read- and write-performance similar to that of RamDisk. SuperSpeed Software recommends enabling the write-deferred (or lazy-write) feature ONLY on systems equipped with an Uninterruptible Power Supply (UPS).
A key prerequisite for SuperVolume is to have, or create, a hard drive partition that is small enough to fit into available physical memory. For example, a system with 1 GB of RAM typically has around 700 MB available for SuperVolume. Therefore, a 700 MB disk partition or volume could be mirrored in RAM by SuperVolume. Note: caution should be exercised to leave sufficient memory free for the operating system, programs and services.
In the explanation above we talk about putting data (graphics, video, database etc.) on the SuperVolume partition or volume. Why? Because this data is the most frequently used. If there is enough RAM then entire programs, like action games, can be installed there and accelerated!
Creating the separate disk partition or volume required by SuperVolume may require the use of third-party disk partitioning software such as Partition Magic®.

SuperSpeed’s software
has allowed us to increase the transactional capacity and has improved the performance of our integrated commerce and database servers that support each transaction. Before, we were able to support 20,000 transactions per minute. Now, we move 100,000 transactions in the same amount of time using fewer servers and a RAM-based database. That’s a 500-percent increase."
