Product Overview

Cisco ® Storage Media Encryption (SME) protects data at rest on heterogeneous tape drives and virtual tape libraries (VTLs) in a SAN environment using highly secure IEEE Advanced Encryption Standard (AES) algorithms.
Cisco SME hardware and software are fully integrated with the Cisco MDS 9000 Family portfolio. Encryption is performed as a transparent Fibre Channel fabric service, which greatly simplifies the deployment and management of sensitive data on SAN-attached storage devices. Unlike other approaches, Cisco SME requires no downtime to deploy. Cisco SME is built on a system architecture based on Federal Information Processing Standards (FIPS) and offers highly secure, comprehensive key management, with support for offline media recovery (Figure 1).

Features and Benefits

Cisco SME provides a complete, integrated solution for encryption of data at rest on heterogeneous tape drives and VTLs. Storage in any virtual SAN (VSAN) can make full use of Cisco SME, providing exceptional flexibility for provisioning this transparent fabric service. Cisco SME requires no SAN reconfiguration or rewiring, eliminating downtime for deployment.
Cisco SME employs clustering technology to enhance reliability and availability, enable automated load-balancing and failover capabilities, and simplify provisioning. To simplify management, this encryption service is provisioned as a single, logical SAN fabric feature rather than as individual switches or modules.
Secure lifecycle key management is included, with essential features such as master key rekey, key archival, key shredding, automatic key replication across data centers, high-availability deployments, and export and import for single- and multiple-site environments. Provisioning and key management for Cisco SME are both integrated into Cisco Data Center Network Manager (DCNM); no additional software is required for management.
Cisco SME includes the following features:

• Rapid, scalable deployment: Cisco SME performance can easily be scaled up by adding more Cisco MDS 9000 Family switches or modules. The innovative Fibre Channel redirect capabilities in the Cisco MDS 9000 SAN-OS and NX-OS Software enable traffic from any switch port to be encrypted without the need to reconfigure or rewire the SAN.

• High availability: Cisco SME services employ clustering technology to create a highly available solution. The cryptographic cluster enhances reliability and availability, enables automated load balancing and failover capabilities, and simplifies provisioning as a single SAN fabric service rather than as individual switches or modules. Additionally, Cisco Key Management Center (KMC) supports 1+1 high-availability deployments.

• High level of security: Cisco SME uses strong, IEEE-compliant AES 256 encryption algorithms to protect data at rest. Advanced Cisco MDS 9000 SAN-OS and NX-OS Software security features, such as Secure Shell (SSH), SSL, RADIUS, and Fibre Channel Security Protocol (FC-SP) provide the foundation for a secure FIPS architecture.

• Comprehensive lifecycle key management: Cisco KMC provides dedicated key management for Cisco SME, with support for single- and multiple-site deployments, including automatic key replication across data centers and high-availability deployments. Cisco KMC provides essential features such as master key rekey, key archival, highly secure export and import and translation for distribution, and key shredding.

• Integrated management: Cisco SME is configured and provisioned using the Cisco MDS 9000 Family command-line interface (CLI) or Cisco DCNM; no additional management software is needed. In addition to consistent management interfaces, Cisco SME supports role-based access control (RBAC) and RADIUS and TACACS+ servers for unified credentials management.

Additional features and benefits are presented in Table 1.

Table 1. Additional Features and Benefits

Feature

Benefit

VSAN independence

Traffic on any VSAN can fully use Cisco SME encryption capabilities, providing outstanding flexibility for provisioning and load balancing.

Data compression

To increase the utilization of tape media, Cisco SME provides an option to compress tape data before encrypting it.

Smart cards

For increased operating security, smart cards are offered to protect master keys, facilitate master key escrow, and help prevent unauthorized cryptographic cluster formation and key recovery.

Investment protection

In addition to supporting heterogeneous storage devices, the multipurpose hardware used by Cisco SME supports Cisco MDS 9000 Family storage network services and applications, providing solid investment protection.

Ordering Information

Table 4 lists product ordering information for Cisco SME licenses and components.
Cisco SME also requires Cisco MDS 9000 Family hardware modules or switches that support this feature. The following hardware includes encryption units suitable for Cisco SME:

• Cisco MDS 9222i Multiservice Modular Switch (MMS)

• Cisco MDS 9000 18/4-Port MSM

• Cisco MDS 9000 16-Port SSN

• Cisco DCNM for SAN Advanced Edition is required to run Cisco KMC. A single Cisco KMC can support a multisite deployment. Two instances provide 1+1 high availability.

• The web client (supported by Cisco DCNM for SAN Advanced Edition) provides the Cisco SME provisioning wizard. At least one instance of Cisco DCNM for SAN Advanced Edition is thus required.

For more information about ordering hardware and about Cisco DCNM requirements, see the Cisco MDS 9000 Family product literature at http://www.cisco.com/en/US/products/hw/ps4159/ps4358/index.html.
