MDS 9000 Family network-assisted storage applications offer deployment flexibility and investment protection by 

allowing the deployment of appliance-based storage applications for any server or storage device in the SAN 

without the need to rewire SAN switches or end devices. Easy insertion and provisioning of appliance-based 

storage applications is achieved by eliminating the need to insert the appliance into the primary I/O path between 

servers and storage devices. 

Cisco Data Mobility Manger (DMM) is a SAN-based, intelligent fabric application offering data migration between 

heterogeneous disk arrays. Cisco DMM offers rate-adjusted online migration to enable applications to continue 

uninterrupted operation while data migration is in progress. Advanced capabilities such as data verification, 

unequal-size logical unit number (LUN) migration, and multipath support provide flexibility and meet the high-

availability requirements of enterprise data centers. DMM is transparent to host applications and storage devices, 

and it can be introduced without the need to rewire or reconfigure the SAN. Cisco Data Center Network Manager 

(DCNM) for SAN is used to administer Data Mobility Manager; no additional management software is required.

The Cisco MDS 9000 I/O Accelerator (IOA) is a SAN-based intelligent fabric application that provides SCSI 

acceleration to significantly improve the number of SCSI I/O operations per second (IOPS) over long distances in a 

Fibre Channel or FCIP SAN by reducing the effect of transport latency on the processing of each operation. The 

feature also extends the distance for disaster-recovery and business-continuity applications over WANs and 

metropolitan area networks (MANs). I/O Accelerator can be deployed in conjunction with disk data-replication 

solutions such as EMC Symmetrix Remote Data Facility (SRDF), EMC MirrorView, and HDS TrueCopy to extend 

the distance between data centers or reduce the effects of latency. I/O Accelerator can also be used to enable 

remote tape backup and restore operations without significant throughput degradation. 

I/O Accelerator (IOA) includes the following features: 

● 

Transport independence: IOA provides a unified solution to accelerate I/O operations over the MAN and 

WAN. 

● 

IOA as a fabric service: IOA service units (interfaces) can be located anywhere in the fabric and can provide 

acceleration service to any port. 

● 

Speed independence: IOA can accelerate 1/2/4/8/10/16-Gbps links and consolidate traffic over 8/10/16-

Gbps ISLs. 

● 

Write acceleration: IOA provides write acceleration for Fibre Channel and FCIP networks. Write acceleration 

significantly reduces latency and extends the distance for disk replication. 

● 

Tape acceleration: IOA provides tape acceleration for Fibre Channel and FCIP networks. Tape acceleration 

improves the performance of tape devices and enables remote tape vaulting over extended distances for 

data backup for disaster-recovery purposes.
