One of the following disk unit controllers is required to support the disk units.

For more information on these controllers see page and page They occupy one card slot in the Integrated Expansion Unit. Internal disk units of different technology ie, different feature numbers , but of the same capacity can be either mirrored or RAID-5 protected on the Model Additional disk capacity may be ordered for storing.

One quarter of each of these four disk units is allocated to parity information that is automatically maintained as part of the RAID-5 protection feature. Additional disk units may be added to the Integrated Expansion Unit with full capacity being available on each disk.

When the maximum of eight disk units has been reached in the Integrated Expansion Unit, the parity information may now be spread across all eight disk units. One eighth of each disk unit is allocated to parity information which gives true RAID-5 protection having data and parity information on all disk units. Having parity spread across eight disk units gives better performance in the event of a disk unit failure as the data required to dynamically rebuild the data on the failed disk is being accessed from an eighth of the disk units as opposed to a quarter.

If one disk unit fails it cannot be used to read or write data. The disk unit controller , will then read the parity and data from the same data areas on the other disk units to dynamically rebuild the original data from the failed disk units to satisfy ongoing read requests. When data needs to be written, the controller will generate the parity information for the failed disk unit as if it were still operating.

There is no concurrent maintenance on the Model The failed disk unit must be replaced at a scheduled time and the data is dynamically rebuilt onto the new disk unit from the other disk units.

Not only this there are many other important features that have made AS a widely popular. OS, the operating system in AS server provided 5 security settings value from 10, 20, 30, 40, 50 since it ventured.

Though value 10 setting has become obsolete and removed from the latest IBM i system, other 4 values remain and are used according to the business requirements of organizations. Level It promised no security at all. It did not require any password to sign into terminal session. Therefore this level has been removed. Level It provides sign on password security which means once logged in users will have access to all the objects on the system.

It was once used as a default setting in the system. Level Provides object authority to the users. Users require object level access planning and implementation. Level This level is now the default setting in all the IBM i system. It ensures integrity protection and separates the user domain from the system domain. All the requests that are made from unapproved interfaces are not allowed. Level Adds additional integrity protection features which meet the U.

It is recommended that organizations go for the highest security settings as this ensures fool proof protection of data. Well, it completely depends on your system capabilities and software, so make sure that your software run on the OS with level 40 security settings as it is the default in every system.

If not level 40, Level 30 can be used if you have software issues on implementing level But while using level 30 you should be confident enough on how to implement object access controls. Break up your user community and create certain group profiles for each set and then implement your access controls on the group profiles rather than providing coding controls for each individual user profile. When we talk about Level 20, security issues arise. Therefore this level should be avoided most of the times.

If you are dicey about using your third-party software on upgraded system then you can activate audit logging few weeks before changing the level and see if there are any problems. This process will make it easier to switch from level 30 to above. In case of moving from level 20 to level 30, process can be a bit tedious. Generally, the issue arises with legacy system as those previously depended on application security and menu controls as their primary safeguards. Security features in IBM I have been upgraded since its launch.

IBM i is widely used in organizations and industries where reliability, efficiency and security are the top priorities. It is mainly used for ERP and many mission critical assignments. The study is based on the settings on servers and partitions, providing real-world information about how organizations around the world secure this powerful OS.

The first power processor saw its existence in the then AS servers. Gradually, these processors improved and found the way to the IBM Power systems.

As many organizations are switching to cloud hosting, the IBM i cloud is giving a large amount of support in the same. IBM works with its channel partners to deliver the best to its users and also provides customized cloud solutions. AS now known as IBM i is updated and modified according to modern technology. As it still has its foundation based on AS, data security and authenticity is above all.

Industries like finance, logistics, insurance, manufacturing, transportation etc. The report also shows industry wise segmentation of the IBM i users worldwide.

Looking at these figures one thing is clear that this technology is not gone but is an integral part for many big tech giants.
