Comments
1)
IUP Integrated Universal Processor:
Acts as universal ICP/IDP/VLP for the
CentricStor VTA-500 / VTA-1000
2)
ICP Integrated Channel Processor:
Performs the data link to the connected host
systems. Channels (mixed possible):
• ESCON / Type S
• Fibre Channel
• FICON (not for VTA-500 / VTA-1000)
ESCON: Enterprise Systems CONnection is the fibre optic
connection for IBM mainframes
Type S: Fujitsu Siemens Computers mainframe fibre optic
connection
FICON: Fiber Connection, IBM’s fiber optic channel
technology that extends the capabilities of its
ESCON standard.
3)
IDP Integrated Device Processor: Performs the data
transfer to the physical tape drives. Typical 1 /
maximal 8 physical tape drives per channel:
• SCSI (direct / daisy chain)
• Fibre Channel (direct / via Switch)
4)
VLP Virtual Library Processor:
Performs the central management processes
5)
VDR Virtual Drive Replication
6)
TVC Tape Volume Cache
7)
Performance Average data throughput from/to the host during
read and write access
8)
Maximum It is not possible to configure all components
with their maximum in one system.
