IBM Research’s Personal Memory Organizer can help organize your memory and access information that otherwise might get lost. This technology uses images, sounds, and text recorded on everyday mobile devices to help people recall names, faces, conversations and other important information.

This is my IBM xseries 345 home server. I got this from work for free. They were going to throw it away. **UPDATE: I have tested and installed Ubuntu on the Dell poweredge 2500. It runs fine. **UPDATE: Some specs on the xseries 345 server. -SCSI Raid Card [IBM (02R0970) SCSI Controller] -Processor 1st [3.067ghz/512kb Cache/533mhzfsb] -Fans 8x [Part Number 06P6250] -Ram Slot 1 & 2 [512MB PC2100] Slot 3&4 [256MB PC2100] -Power Supply [514Watt Part Number 49P2167] I cleared all the disk space and installed Ubuntu 9.04 (Jaunty Jackalope). I currently have a proxy setup on this machine for learning purposes. I also use it as a network storage unit. The LAN is capable of 10/100/1000. I am running a switch that supports 10/100/1000. My Mac also supports 10/100/1000 so I get blazing fast file transfer speeds between the two. I also have two file storage add-on units that I am not using yet. I also have a Dell poweredge 2500 and a Dell poweredge 2450. The 2450 is a pile of nothing at the moment. The 2500 appears as if it could run just fine.

IBM NANOTECHNOLOGY VERY COOL! Moving Individual Atoms with Tuning Forks for Memory Storage

Information that has been encrypted by the LTO-4 drive can be recorded on both medias of LTO ultrium WORM and rewritable, so that the data integrity could be maintained. The IBM LTO 35L2086 universal cleaning cartridge is compatible and effective in all the LTO ultrium drives. LTO4 tape technology can read LTO-2 2nd generation ultrium media with speed up to 35 megabytes/sec and can read as well as record data on LTO3 media at rate of 80 megabytes/sec. LTO-4 can record & write the LTO ultrium-4 cartridge at speed of 120 megabytes/sec.

IBM LTO4 tape drive offers data throughput at 240MBps with 1.6-TB recording capacity. IBM 95P4437 LTO4 has the WORM (write once read many) media and provides the reliable 256-AES Encryption technology. Consumer information is the most valuable asset for the organization and therefore there should be a reliable and robust storage solution for its recording and protection. IBM LTO4 tape has all the latest and innovative features to protect & record the precious and vital information for longer time periods.

There are numerous challenges relating to the protection of data tapes. The data tape needs to be protected when it is transferred from main data center and access to the information is needed when it arrives at the business partner’s business continuance location. Encryption is the most powerful and reliable mechanism for data protection. Encrypted information is in the un-readable form. Encryption key is managed by the tape library, at system level or through the application. The effect of encryption on the performance of IBM LTO 4 tape technology is less than 1% and reduces overall cost.

Data encryption requires a “key” and an encryption technique. Keys are bit streams comprising of 128, 192 & 256-bits. The most commonly used technique for encryption is the AES (Advanced Encryption Standard). Encrypted information is in the un-readable form. Encryption key is managed by the tape library, at system level or through the application. The effect of encryption on the performance of IBM LTO 4 tape technology is less than 1% and reduces overall cost. IBM LTO4 95P4436 tape supports encryption and compression thus stabilizing the efficiency of ultrium storage media. So there is no longer need for server resources or dedicated hardware appliances to encrypt the data.

IBM was the pioneer in introducing the tape encryption technology. Specifications of LTO-4 ultrium tape supports increased capacity and enhancements of performance. Single LTO4 tape cartridge can accommodate data of 8 first generation LTO1 ultrium cartridges and compressed information of 1.6 terabytes. IBM LTO 4 technology supports native data rate up to 120MB/s, assisting the organizations in efficient management of the backup windows. LTO4 tape specification includes all the advantageous technologies and techniques of third generation LTO3.

IBM ultrium LTO4 has independent tape-loader, ECC (Error Correction Code) and the WORM capability. IBM LTO-4 technology has the statistical analysis & reporting feature that secures the data and improves the reliability. Hardware of IBM LTO4 technology features attachments to ultra-160 LVD-SCSI, 3 GB/s SAS, or 4 GB/s FC with system of encryption. 128MB internal buffer was used in the LTO-3 tape drive which has been doubled to 256 megabytes in the LTO-4 tape drive.

IBM LTO 4 tape offers cost-efficient and reliable backup solutions. IBM LTO4 95P4450 tape performance.

LTO data storage technology is more advantageous and has gain more success and popularity due to its “open” format. Linear tape open is highly scalable and features breakthrough technologies that make it ideal to meet the challenges of current data intensive applications and strict laws. Highly efficient IBM LTO offers multiple sources of media and products.

IBM, Seagate and HP combined their efforts and engineered a new innovative LTO technology that offers a viable and ideal storage medium in a growing complex of backup data storage options. IBM LTO-3 tape has established new standards for performance, capacity and data throughput. Exceptional compatibility of high capacity IBM LTO3 tape enables the users to interchange their sensitive data across different platforms. Increasing needs of the modern backup applications are efficiently accommodated by the new advanced IBM LTO-3 media format. 24R1922 is the part number of the highly economical IBM ultrium 3 cartridge whose native capacity is 400 GB. The compression ratio offered by the IBM LTO-3 is 2:1. This means that the data recording capability of IBM LTO-3 tape will be twice as that of its native capacity.

Ultrium is a powerful and high capacity specification of linear tape open whose per cartridge native capacity offerings range from 100GB (LTO-1 media tape) to 800GB (LTO-4 tape). High performance LTO-3 tape products developed by IBM are carefully engineered to meet the organizations’ needs at an affordable cost. The design of IBM LTO-3 tape comprises of a single hub that allows optimized packaging of media within the ultrium cartridge.

IBM has developed an exceptional and reliable compression algorithm for the LTO-3 tape format which doubles its speed as well as its data capacity. The data tracks of the IBM 24R1922 tape are further divided into 4 areas. Each area is called “data band”. Servo information bounds the top & bottom of each data band. Data is written on each data bands of IBM LTO-3 tape media one at a time. Cartridge memory is unique feature included in the IBM LTO cartridges. Upon loading the tape into the drive, it reads the contents held in the 4KB cartridge memory to accelerate its performance and upgrade the data throughput. The cartridge memory is non-volatile and is embedded in the robust cartridge shell of IBM LTO-3. Users of IBM LTO tape format are offered more luxury as they do not have to insert the cartridge into the drive for retrieving the information about initialization, manufacturer’s data, and calibration information.

Dedicated dual servo mechanism of IBM ultrium-3 increases the data integrity. IBM LTO-3 ultrium technology features error correction system which comprises of 2 levels. This error correction system is very effective and recovers the information from the longitudinal scratches. When the LTO data tapes are being manufactured, the servo bands are recorded onto the media tape. If any of the elements of servo becomes corrupt or defective, the head of the tape drive continues to track because of the 2nd redundant servo mechanism. The servo frame in IBM LTO-3 ultrium format encodes the words in longitudinal position which enables the data administrators to retrieve information from the absolute areas along the entire tape’s length.
