AIT versus LTO: still relevant

AIT. technology - is the ideal backup solution for telecommunications companies. - Internet service providers and telephone. Extremely quiet and compact solutions AIT can save on maintenance, creating a minimum load on the cooling system and power compared to the noisy and hot LTO Ultrium, yet providing the necessary speed of data access and with sufficient storage. All this, combined with exceptional reliability data storage in a compact ( 4-fold less than LTO) AIT- cartridge.

Today, low-cost devices AIT-3Ex and AIT- 4 allows you to create an extremely cost-effective backup system with minimal cost, allowing to be placed on a single cartridge up to 390 GB AIT-3Ex or 520 GB AIT- 4 with innovative data compression system (2. 6:1 ).

AIT format is:.
* Wear belts AME, virtually no contaminating the drive head, can get in the 2nd higher density recording than on a normal (MP) for the LTO Ultrium tape.
* Special mechanism for cooling the drive.
* 64- kilobitny memory chip built into the drive provides high-speed location and file access.
* Rapid charging is compared with the tape LTO Ultrium.
* Built-in cleaning up the drive heads, which is invoked when a large number of errors.
* Each AIT drive is certified for 100% load ( at the DAT 320 is only 12 %, the DAT 160 - 40%).
* Experience shows that the LTO- device performance drops sharply when the server generates a non-uniform discontinuity in the data stream (as most servers are back up ). And due to the small linear tape speed stop-start mode of operation has little effect on the performance of AIT. Therefore, in the real world drives helical recording have better performance than LTO devices.
* Low noise, minimal power consumption and cooling requirements.

Thus, using the drives AIT, you minimize the cost of ownership of your backup system, reducing the cost of service due to less whimsical arrangements, embedded systems clean and efficient cooling, lower power consumption, noise level and high-density storage.
