Cisco MDS 8Gb Fabric Switch for HP BladeSystem c-Class: технические характеристики и документация

Cisco MDS 8Gb Fabric Switch for HP BladeSystem c-Class

The Cisco MDS 8Gb Fabric Switch for HP BladeSystem c-Class delivers an embedded option for HP BladeSystem c-Class customers deploying storage area networks in their enterprise. The integrated design frees up rack space, enables a reduction of components, and utilizes shared power and cooling within the BladeSystem enclosure resulting in space and cost savings. The Cisco MDS 8Gb Fabric Switch supports VSAN, an industry standard for fabric virtualization enabling more efficient network use. The N-Port Virtualizer FlexAttach mode streamlines the infrastructure by reducing the number of domains to manage while enabling the ability to add or move servers without impacting the SAN. Advanced traffic management features optimize the fabric. Management is simplified with a broad range of integrated tools and switch management is integrated with HP BladeSystem management creating a unique and tightly integrated experience for server and storage administrators.

Cisco MDS 8Gb Fabric Switch for HP BladeSystem c-Class

Key Features and Benefits

The Cisco MDS 8Gb Fabric Switch for HP BladeSystem c-Class

Integrated design lowers TCO and enables higher levels of availability

The Cisco MDS 8Gb Fabric Switch hot-plugs into the back of the HP BladeSystem c-Class enclosure, freeing up rack space. Interconnect internal to the BladeSystem reduces cabling, SFPs and associated costs. Shared power and cooling resources further reduces cost and additional points of failure.

Exceptional performance, scalability and flexibility

Employs high speed 8 Gbps technology for storage networking. N-Port Virtualizer feature uses NPIV technology to eliminate domain count concerns and FlexAttach mode extends the technology to enable servers to be added or moved without impact to the SAN.

High availability

Designed for environments where downtime is not an option. Up to six FC switches are supported in the BladeSystem enclosure. Hot-pluggable design supports non-disruptive upgrades, VSANs for fault isolation, and PortChannels for ISL resiliency.

Flexible licensing

Dynamic and growing businesses require the flexibility to manage their investment wisely. Designed to scale as business needs dictate with the option of a 12-port model and a 12-port upgrade license.

Traffic management

Simplifies deployment while optimizing core edge fabrics with support for virtual output queuing, flexible buffer credit allocation, PortChannels, Fabric Shortest Path First (FSPF), and more.

VSAN support

Support for up to 32 VSANs per switch that can be zoned as its own fabric enables efficiency, lower cost through shared usage, the flexibility of independent configuration control, and increased security through isolation of devices on the same physical SAN.

Long distance support

Individual ports can be configured with short- or long-range SFP+ optics for connectivity of up to 10 kilometers.

Broad range of management options

Simple and consistent with support by the Cisco MDS 9000 family management tools including a CLI, Cisco Fabric Manager and a standards-based API supporting SNMP and SMI-S. Also supported by HP unified server and storage management tools.

Comprehensive security

Offers an extensive security framework to protect highly sensitive data crossing today's enterprise networks.

Advanced diagnostics and troubleshooting tools

Integrates the industry's most advanced analysis and debugging tools for proactive diagnostics, verification of connectivity and route latency, and capturing and analyzing traffic.

Configuration support

Please see the following Web site for configuration support at:
http://h18000.www1.hp.com/products/storageworks/san/documentation.html

Cost Effective Intelligent Storage networking

Powered by Cisco MDS 9000 NX-OS Software, offers intelligent storage networking capabilities such as Virtual SANs (VSANs), PortChannels, quality of service (QoS), and security for cost-effective design, deployment, and management of enterprise SANs.

Highly available platform for mission-critical deployments

Designed for environments where downtime is not an option. It offers non-disruptive software upgrades, VSANs for fault isolation, and PortChannels for Inter-Switch Link (ISL) resiliency.

Flexibility

Offers up to 24 8/4/2-Gbps auto-sensing Fibre Channel ports with 8 Gbps of dedicated bandwidth to each port, and an aggregate platform bandwidth of 384 Gbps. Starts with a base configuration of 12 ports (8 internal and 4 external ports) with flexibility to upgrade in the field to 24 ports using 12-port upgrade activation license .The N-Port Virtualizer (NPV) feature employs industry-standard N-Port Virtualization technology to eliminate domain count concerns and enable fabric interoperability. FlexAttach further extends NPV to enable servers to be added or moved within or between BladeSystem enclosures without any impact to the SAN.

There can be a total of 16 internal ports for connectivity to 16 server blades and 8 front panel ports for connectivity to the SAN, server, or storage devices.

Simplified storage management

Includes built-in storage network management, with all features available through a command-line interface (CLI) and the Cisco Data Center Network Manager (DCNM).

Comprehensive security framework

Supports RADIUS and TACACS+, port security, fabric binding, Fibre Channel Security Protocol (FC-SP) host-to-switch and switch-to-switch authentication, Secure FTP (SFTP), Secure Shell Version 2 (SSHv2) and Simple Network Management Protocol Version 3 (SNMPv3) implementing Advanced Encryption Standard (AES), VSANs, hardware-enforced zoning, broadcast zones, and per-VSAN role-based access control (RBAC).

Sophisticated diagnostics

Industry-leading intelligent diagnostics such as Fibre Channel Ping, Fibre Channel Traceroute, Switched Port Analyzer (SPAN), Cisco Fabric Analyzer, and integrated call-home capability enhance reliability, facilitate faster problem resolution, and reduce service costs.

Interoperability

Common platform architecture and the use of Cisco MDS 9000 NX-OS Software intelligent storage-networking services across all Cisco MDS 9000 family switches reduces ongoing operating expenses by providing a consistent set of provisioning, management, and diagnostic capabilities. Offers compatibility with a broad range of HP servers and operating systems, as well as storage devices; see current compatibility matrix.

Software Components, Included

NX-OS

Cisco MDS 9000 NX-OS delivers numerous advanced storage networking capabilities for the Cisco MDS 9000 Family of Multilayer Intelligent Directors and Fabric Switches.

Cisco Data Center Network Manager

Cisco Data Center Network Manager is a responsive, easy-to-use Java application that simplifies management across multiple switches and fabrics. Cisco Data Center Network Manager enables administrators to perform vital tasks such as topology discovery, fabric configuration and verification, LUN security, monitoring, and fault resolution. All functions are available through a secure interface, which enables remote management from any location. Cisco Data Center Network Manager may be used independently or in conjunction with third-party management applications. Cisco provides an extensive API for integration with third-party and user developed management tools.

Software Components, Optional

HP StoreFabric Data Center Network Manager Package

The "Standard" Cisco Data Center Network Manager software that is included at no charge with the Cisco MDS 8Gb Fabric Switch for HP BladeSystem provides basic switch configuration and troubleshooting capabilities. HP's C-series StoreFabric Data Center Network Manager (DCNM) Package extends Cisco Data Center Network Manager by providing historical performance data collection for network traffic hot-spot analysis, centralized management services and advanced application integration.

HP MDS 9100 Enterprise Package License
