Cisco Storage Media Encryption

Cisco Storage Media Encryption (SME) provides a complete, integrated solution for encryption of data at rest on

heterogeneous disks, tape drives and virtual tape libraries (VTLs) in SAN environments. Storage in any VSAN can

make full use of Cisco SME capabilities, providing exceptional flexibility for provisioning this transparent fabric

service. Cisco SME requires no SAN reconfiguration or rewiring, thereby eliminating downtime for deployment. Cisco

SME employs clustering technology to enhance reliability and availability, enables automated load-balancing and

failover capabilities, and simplifies the provisioning process. The Cisco SME encryption service is managed as a

single, logical function in the SAN rather than as a feature that works on individual switches or modules. Secure

lifecycle key management is included along with essential capabilities such as key archival, shredding, and export

and import for single- and multiple-site environments. Cisco SME provisioning and key management are both

integrated into Cisco Data Center Network Manager for SAN (DCNM-SAN); no additional software is required for

management.

Cisco Data Mobility Manager

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. Cisco DMM is transparent to host applications and storage devices. Cisco

DMM can be introduced without the need to rewire or reconfigure the SAN. Cisco DCNM-SAN is used to administer

Cisco DMM; no additional management software is required.

I/O Accelerator

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

acceleration to significantly improve the number of SCSI I/O operations per second 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). IOA 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. IOA can also be used to enable remote tape backup and restore operations

without significant throughput degradation. 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 independent: IOA can accelerate 1/2/4/8/10-Gbps links and consolidate traffic over 8/10-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.

●

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

costly infrastructure upgrades. Integrating 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.
