IBM Fiber Channel Storage for System x
The Storage Solutions two day class starts with connectivity and protocols used to connect storage to servers. Beginning with the DS3000 family, emphasis is on the cabling configuration and architectures of these storage units along with the performance differences between the SATA, SAS, and fiber channel devices, followed by the DS4000 family and expansion units EXP420, EXP810, and EXP5000. Managing the DS4000 controller, starting with the power on sequence and the value of DACstore is discussed plus the installation of the IBM DS Storage Manager user management interface. Arrays and logical drives are covered along with the dynamic operations. How to partition logical drives and the use of FlashCopy and VolumeCopy will also be covered. Managing DS3000 controllers starts with the Storage Manager interface, some configuration parameters that are specific to the DS3300, how to create arrays and logical drives and last you will look at the codes associated with the DS3300 and iSCSI. Problem Determination is a key skill, and we cover a variety of topics by defining LED states, the Recovery Guru usage and the QLogic Fast!UTIL and QLogic SANsurfer for diagnostics. Performance and those factors that affect basic disk performance, the performance monitor tool, and tuning recommendations are covered in this course.
