I hereby declare that the work presented in this internship report entitled "IBM Server Maintenance, Servicing and Networking of an Organization" was done by me under the supervision of Mr. Narayan Ranjan Chakraborty Senior Lecturer, Department of Computer Science and Engineering, Daffodil International University, in partial fulfillment of the requirements for the bachelor's degree in Computer Science and Engineering. Narayan Ranjan Chakraborty Senior Lecturer, Department of Computer Science and Engineering, Daffodil International University, Dhaka.
In-depth knowledge and keen interest of our supervisor in the field of "IBM Server Maintenance, Servicing and Networking Organization" to carry out this internship. His endless patience, professional guidance, constant encouragement, constant and energetic supervision, constructive criticism, valuable advice, reading many poor drafts and correcting them at all stages made this internship possible. Finally, I would like to thank my family, especially my parents for their constant support and encouragement throughout the entire period of this internship.
Finally, my documentation for this internship indicates a successful completion of the tasks assigned to me. I need to show about Redundant Array of Inexpensive Disks (RAID). This chapter shows different types of RAID.
Internship Enterprise
About the Company
IT Services Offered
All remote engineers support their customer and work strongly and confidently in remote area for whole Bangladesh. Our expertise is a clear perception of the business goals of our customers, the selection of the most suitable technology and the effective design and development of solutions that satisfy the identified business needs. We firmly believe that this increases business value much more than simply developing the hardware and network applications sector.
Most job opportunities exist in Dhaka, Chittagong and as a percentage of population. A government and non-government origin will have completely different needs depending on the services it provides.

System Hardware Information of a server
Integrated Management Module
In IBM System x servers, the Integrated Management Module (IMM) consolidates the service processor functionality, Super I/O, video controller, and remote presence functions into a single chip on the server's system board. Virtual Light Path: Where can see any errors, CPU1 status, CPU fan status, HDD fan status, System fan status, DIMM memory status, PCI status, PCIE SAS status, Plan status, Battery status, BMC Heart Beat status. Event log: Event logs are special files that record important events on your computer, such as when a user logs on to the computer or when a program encounters an error. Fig: 3.4.5 When these types of events occur, Windows records the event in an event log that you can read using the Event Viewer.
Power/Reboot: The IMM provides full remote power management of your server with power on, power off and reboot operations. Fig: 3.4.7 Additionally, power on and reboot statistics are recorded and displayed to show server hardware availability. Remote control: Remote controls usually work via infrared signals, but sometimes via radio frequency signals Fig: 3.4.8 The remote control can control a number of functions such as volume, channel, track number and other functions. Modern remote control units often have more control functions than are found on the unit itself, which may only have a few primary essential controls.
System Setup: You can configure general operating system settings and computer settings in the Forefront TMG Management console. Fig:3.4.11These settings include changing the computer name and domain membership, viewing certificates installed on the computer. Login Profiles: Use the Login Profiles table to view, configure, or modify individual login profiles.
Each link in the Login ID column is labeled with the configured login ID of the associated profile.Fig3.4.12. Certain login profiles are shared with the IPMI user IDs, which provide a single set of local user accounts (username/password) that work with all the IMM user interfaces, including. Alerting: You can configure remote alert recipients, the number of alert attempts, events that trigger remote alerts, and local alerts from the Alerts link on the navigation panel. Fig 3.4.13 After you configure a remote alert receiver, the IMM sends an alert to that receiver through a network connection when any event selected from the monitored alert group occurs.
Port Assignment: From the Port Assignments page you can view and change the port numbers assigned to the IMM protocols (for example HTTP, HTTPS, Telnet and SNMP).Fig 3.4.14. Network Interface: the Network Interfaces page, you can configure network access settings for the Ethernet connection on the IMM. Configuration files: You can back up, modify, and restore the configuration of the IMM, and view a configuration summary, from the Configuration File page.
Redundant Array of Inexpensive Disks(RAID)
The capacity of a RAID 0 volume is the sum of the capacities of the disks in the set, the same as with spanned. Failure of one disk thus causes the loss of the entire RAID 0 volume, with reduced possibilities for data recovery compared to a broken spanned volume. Striping distributes the contents of files roughly equally among all disks in the set, making simultaneous read or write operations on the multiple disks almost inevitable.
The concurrent operations make the throughput of most read and write operations equal to the throughput of one disk multiplied by the number of disks. If a request is issued to each drive in the set, it can be serviced by the drive that accesses the data first, improving performance. Sustained read throughput, if the controller or software is optimized for it, approaches the sum of the throughputs of each drive in the set, just like for RAID 0.
Write throughput is always slower because each drive must be updated and the slowest drive limits write performance. In the event of a single disk failure, subsequent reads can be calculated based on the distributed parity so that no data is lost. As with RAID 5, failure of a single drive results in reduced performance of the entire array until the failed drive is replaced.[11] With a RAID 6 array, which uses drives from multiple sources and manufacturers, it is possible to reduce most of the problems associated with RAID 5.
RAID 10:RAID 10 works by striping and mirroring your data across at least two disks

Problem and solutions Case Study 1: Case Study 1
Case Study 2
Case Study 3
Initially we can help with the light path diagnostics and saw that there was a yellow error in the LPD.
Case Study 4
