14. MAINFRAME REPLICATION MANAGEMENT
“REFRESHER”
 Hitachi - IBM Compatibility
‒ Hitachi storage has essential compatibility with IBM z/OS
‒ IBM replication management compatibility
‒ Hitachi storage controllers support PPRC, XRC and FlashCopy
commands (assuming applicable software licensing) without additional
HDS-provided software
‒ TrueCopy synchronous is compatible with PPRC
‒ For full-volumes, IBM commands operate on individual replication pairs
‒ But, IBM commands do not support Hitachi Universal Replicator
 Hitachi Business Continuity Manager (BCM) value-add
‒ Reduce complexity, simplify management
‒ Provide enhanced control and visibility
‒ (e.g., support configured and unconfigured devices)
‒ Reduce risk

15.  Automatically discovers Hitachi storage systems and internal
copy volumes
 Uses a single command to manage groups of copy volumes
with common attributes
 Receives auto notification of key copy “state transitions”
 Supports advanced TrueCopy, ShadowImage and Universal
Replicator features
 Real-time view of Universal Replicator
 Single, consistent interface based on Time Sharing Options
(TSO) / Interactive System Productivity Facility (ISPF)
 Standard REXX scripting to customize and automate
 Optional Integration with Replication Manager for combined
mainframe and open systems replication management

• Is an FCIP Tunnel with more than 1 circuit
• FCIP Trunking provides
• Single logical ISL in routing table as a single link, ULP see single link
• Bandwidth Aggregation of each circuit
• Load Balancing per batch across circuits
• Failover to remaining circuits
• Lossless Link Loss (LLL)
• Data in-flight is not lost when a link goes down, will be retransmitted same as with TCP
• In-Order-Delivery (IOD) Does not require IOD to be enabled
• Data in-flight will be delivered in the correct order, even after data lost in-flight
• Works with both FICON and FC
• Supports FastWrite, OSTP, and FICON emulation over multiple circuits
• FCIP Trunking is a proven technology
• Leveraged from widely deployed McDATA/CNT technology

27. FCIP Trunking Concept
Supervisor TCP Session
• Encapsulates the circuits’ TCP sessions within a FCIP Trunk
• Provides granular load-balancing
• Retransmits lost frames due to circuit loss
• For operational links, the TCP sessions within the circuit handle loss
• Ensures FC frames are delivered in order (IOD)
• Prevents IFCC on the mainframe
• Supports FastWrite, OSTP, and FICON emulation
• FCIP Trunk appears as a single logical ISL

With one interface online,
all available bandwidth is
consumed up to the
maximum rate
When a second interface is enabled, the
network experiences a congestion event and the
first interface drops its rate down to the
minimum configured rate. From here it will seek
the ceiling again
The second interface starts
off by claiming its minimum
configured rate
Offline equipment/link
results in available BW
This interface ramps up to fully
utilize the available WAN BW. It
stops seeking a ceiling at the
maximum configured rate

• Solution:
•2 FCIP Trunks
•1 FCIP Trunk per 7800
• 2 circuits in each trunk
•Array sees 2 parallel paths
• ARL used on all 4 circuits
•Max is link BW or interface line rate, whichever is smaller
