Compression: Compression in IOA increases the effective MAN and WAN bandwidth without the need for 

costly infrastructure upgrades. Integration of data compression into IOA enables implementation of more 

efficient Fibre Channel- and FCIP-based business-continuity and disaster-recovery solutions without the 

need to add or manage a separate device. 

● 

High availability and resiliency: IOA combines PortChannels and equal-cost multipath (ECMP) routing with 

disk and tape acceleration for higher availability and resiliency. 

● 

Service clustering: IOA delivers redundancy and load balancing for I/O acceleration. 

● 

Transparent insertion: IOA requires no fabric reconfiguration or rewiring and can be transparently turned on 

by enabling the IOA license. 

● 

Intuitive provisioning: IOA can be easily provisioned using Cisco DCNM for SAN.

IBM Extended Remote Copy (XRC), which is now officially renamed IBM z/OS Global Mirror, is a mainframe-based 

software replication solution widely used in financial institutions worldwide. In the past, Cisco has supported XRC 

over FCIP at distances of up to 124 miles (200 km). The new Cisco MDS 9000 XRC Acceleration feature supports 

essentially unlimited distances. XRC Acceleration accelerates dynamic updates from the primary to the secondary 

direct-access storage device (DASD) by reading ahead of the remote replication IBM System z, known as the 

System Data Mover (SDM). This data is buffered within the Cisco MDS 9000 Family module that is local to the 

SDM, reducing or eliminating the latency effects that can otherwise reduce performance at distances of 124 miles 

(200 km) or greater. This process is sometimes referred to as XRC emulation or XRC extension.

Network Security 

Cisco takes a comprehensive approach to network security with Cisco MDS 9000 NX-OS. In addition to VSANs, 

which provide true isolation of SAN-attached devices, Cisco MDS 9000 NX-OS offers other significant security 

features such as role-based access control (RBAC) and Cisco TrustSec

®

 Fibre Channel Link Encryption and 

supports the industry-standard security protocol for authentication, authorization, and accounting (AAA). Cisco 

MDS 9000 Family management is certified for Federal Information Processing Standards (FIPS) 140-2 Level 2 and 

validated for Common Criteria (CC) Evaluation Assurance Level 3 (EAL 3). 

Fibre Channel Security Protocol (FC-SP) capabilities in Cisco MDS 9000 NX-OS provide switch-to-switch and host-

to-switch authentication for enterprise-wide fabrics. Diffie-Hellman Challenge Handshake Authentication Protocol 

(DH-CHAP) is used to perform authentication locally in the Cisco MDS 9000 Family director or remotely through 

RADIUS or TACACS+. If authentication fails, a switch or host cannot join the fabric.
