the speed of movement of the tape in order to match the data transmission speed of the host
VXA can shift operation (VSO) to enable it to regulate the speed of movement of the tape in order to match the data transmission speed of the host, this rate is adjusted so the VXA become arising can avoid the tape back to pull the tape drive media wear. Exclusion back pull also reduces the mechanical wear of the drive to improve the capacity and reliability of data recovery.
Exabyte Corporation has the tape experience of 20 years, with many of the industry's first VXA technology awareness is not very high, the user the advantages of VXA not understand, which is Exabyte to be addressed.
Mainstream tape technology, in the choice of a specific product, users need from the product price, ease of use and other aspects to measure.
(1) to select cost-effective tape products
SMEs from their own situation, the equipment selection should be high cost performance products as the first choice factors.
The performance of tape storage products is mainly reflected in the capacity and speed, and can generally be based on the date the amount of stored data size, the speed of data growth, data backup cycle to determine the capacity of tape device. For SME users, of Exabyte Corporation VXA-172 Packet tape drives and autoloaders products or, AIT-3 and other more appropriate, roughly equal on both capacity and speed, but the price on the VXA-172 than dominant.
VXA-172 single cartridge capacity of 172GB, transfer rate up to 24MB / s, within two hours backup up to 172GB (compression ratio 2:1) data, VXA-172 Packet tape drives and autoloaders can achieve the desired expansion, when the increase of the amount of user memory, the flexibility to upgrade to 320GB. terms of short-term and long-term, can save the user's total cost of ownership. Price, the VXA price is 2/3 of the price of similar products, cost-effective products in the current low-end market, very attractive to SMEs.
