IBM 3996 Optical Library

Large-scale optical storage for the IBM System i and System p


The IBM 3996 Optical Library is designed to be a large-scale, externally attached, optics storage library that uses 60 GB UDO-2 optical disc technology. The 3996 library is offered in three models and is available for attachment to most models of the IBM System i family of workstations and servers.

This 3996 Optical Library family of optical libraries is being enhanced with support of 5.25 inch, 60 GB UDO Generation 2 technology and the new UDO media provides up to ten times the maximum capacity of media used in the previous generation 3995 optical libraries offered by IBM. The IBM 3996 Optical Library supports permanent WORM and rewritable recording technologies in a single library. The 3996 library offers two options in optical drives: UDO-1 and UDO-2. All model of the 3996 library offer the flexibility of mixing UDO-1 and UDO-2 drives and media in the same library. The IBM 3996 is available as a low voltage differential (LVD) small computer system interface (SCSI) interface connectivity and has an optional barcode scanner to facilitate library inventory.

The 3996 Optical Library is offered in three models; Model 032, Model 080 and the Model 174. Each model supports permanent WORM and rewritable recording technologies in a single library. Model 32 has the ability to handle up to 32 disks, providing up to 1.92 TB of physical capacity. The Model 32 has one optical disc drive and an option for adding a second drive. Model 80 has the ability to handle up to 80 disks, providing up to 4.8 TB of physical capacity. The Model 80 has two optical disc drives with an option of increasing to four drives. When additional drives are added, the Model 80 has the ability to handle up to 72 disks, providing up to 4.32 TB of physical capacity. Model 174 has a physical capacity of up to 10.4 TB; each of the 174 media slots holds a disk with up to 60 GB of optical storage. The Model 174 has two optical disc drives with an option of increasing to four drives. When the additional drives are added, the 3996 Model 174 has the ability to handle up to 166 disks, providing up to 9.96 TB of physical capacity.

The IBM 3996 features an optional barcode scanner in all three optical model offerings. The three main benefits of bar coding are out-of-library media management, faster media inventorying inside the library and added security.

IBM offers a broad systems and storage portfolio combined with decades of experience solving real business problems. With x86, POWER and mainframe systems, disk, tape and network storage systems, IBM can offer the right combination of systems to meet the challenges of your business.


Storage efficiency is more vital than ever. Your disk utilisation rate may be as low as 20% — while the amount of data you are required to store is exploding. IBM Storage can help.


The smarter data centre with improved economics of IT can be achieved by connecting servers and storage with a high-speed and intelligent network fabric that is smarter, faster, greener, open and easy to manage. IBM takes an open, standards-based approach to implement the latest advances in today’s flat, converged data centre network designs.


IBM's comprehensive Systems Software solutions help to centralise, streamline and automate your physical and virtual infrastructure, allowing you to optimise workloads and increase your ability to deliver IT services that align with business goals. Let us show you how IBM Systems Software helps you realise the value of IBM smarter computing, by allowing a more effective use of the advanced features in IBM hardware and operating systems.

Integrated solutions

The reality is that you need an IT infrastructure designed for data, tuned to the task and managed in the cloud. If your IT staff spends all of their time managing IT, they won’t be working with you to drive innovation. You need your infrastructure to help you in the marketplace, to help you innovate, to help you be more competitive, to help you succeed.
