subject: Dell Lto-3 Ultrium Tape Technology Is Ideal For Data Intensive Applications [print this page] Dell LTO 3 tape cartridges are highly scalable and compact. Dell LTO-3 341-2647 cartridge is the most economical tape storage medium for high volume and demanding backups. Highly compact Dell LTO-3 media tapes provide efficient data recording and are very easy-to-handle. Dell ultrium-3 data cartridges ensure efficient and reliable data archiving for longer time periods. Dell LTO-3 tape technology offers high output characteristics and high recording density that are required by the advanced data intensive applications. Robust technology and innovative features of Dell ultrium-3 tape format offers the durability and data security to protect your valuable information.
Dell tests these tapes on the Dell systems before their shipment, which ensure its outstanding performance and compatibility. Dell ultrium-3 format is also supported and backed up by Dell Tech Support. Dell 341-2647 ultrium tape features a reliable and efficient error correction algorithm which ensures recovery of recorded information in case the data is lost form one track. The information being recorded onto the Dell LTO-3 tape media is verified by the read head by reading it back. The reading heads in the LTO-3 drive are located behind the writing heads. This efficient recording system rewrites the data that fails in the first attempt thus increasing the data integrity and lowering the error rate.
Dell LTO-3 ultrium cartridges tape is wrapped around a single reel. The tape cartridge has a leader-pin onto which the tapes end is attached. The LTO tape drive uses this leader pin for grasping the tape reels end, and then afterwards mounts it inside the tape drive. When the tape cartridge is pulled out from the tape drive, the leader pin with the help of a small spring adjusts itself to the move to the opening of the ultrium tape cartridge. Each Dell LTO-3 cartridge contains a memory chip which comprises of 128 memory blocks. Each of the memory blocks has 32 bytes; this means that the total memory of LTO cartridge memory is 4096 Bytes or 4 KB. One block of the LTO cartridge memory is written/read at a time by the help of RF interface. LTO memory chip help the LTO tape drives to differentiate and identify the different versions of LTO tape format. Cartridge memory reader is included in all the LTO-3 backup tape drives.
A very efficient data compression method has been employed in the Dell LTO3 tape format called SDLC (streaming lossless data compression). A header bit is added to each written block of data whether it is in native or compressed form. A copy of the ram information is saved for each data block the compression algorithm works on in the Dell LTO-3 tape technology. When the data compression algorithm compresses the information, it compares the compressed block of data with the raw block of information. After comparing it records the data block on to the tape media which is smaller of the two. The data compression process increases the size of inputs. The efficient data compression technology utilized by the Dell LTO-3 tape format achieves a ratio of 2:1. Dell LTO-3 tapes data compression process uses the extra bit for differentiating the compressed data block from the raw blocks.
