The IBM® System Storage® SAN768B and IBM System Storage

SAN384B fabric backbones are highly robust network switching plat-

forms designed for evolving enterprise data centers. Each machine

combines breakthrough performance, scalability and energy efficiency with long-term investment protection. Supporting open systems and

System z® environments, they address data growth and server virtual-

ization challenges; enable server, SAN and data center consolidation;

minimize disruption and risk; and reduce infrastructure and adminis-

trative costs.

Built for large enterprise networks, the SAN768B has eight vertical

blade slots to provide up to 512 8-Gbps Fibre Channel ports. The

SAN384B is ideal for midsize core or edge deployments, providing

four horizontal blade slots and up to 256 8-Gbps Fibre Channel ports.

The flexible blade architecture also supports FCoE, fabric-based

encryption for data-at-rest and SAN extension advanced functionality for high-performance server I/O consolidation, data protection and

disaster recovery solutions.

The SAN768B and SAN384B are extremely efficient at reducing

power consumption, cooling and the carbon footprint in data centers.

While providing exceptional performance and scale, these networking

backbones use less than one watt per Gbps—significantly more effi-

cient than alternate offerings.

System Storage

The SAN768B and SAN384B build on years of innovation,

using the core technology of systems designed to perform at

greater than 99.999 percent uptime in the world’s most

demanding data centers. With its intelligent sixth-generation

application-specific integrated circuits (ASICs) and advanced

hardware and software capabilities, the SAN768B and

SAN384B provide a reliable foundation for fully connected

multiprotocol SAN fabrics capable of supporting thousands

of servers, storage and networking devices.

As members of the IBM System Storage family of b-type

SAN products, the SAN768B and the SAN384B are designed

to participate in fabrics containing other b-type and m-type

devices manufactured by Brocade. This versatile hardware

can serve as the backbone in a complex fabric and provide

connections to other b-type and m-type directors, switches

and routers.

Fabric optimization services The IBM System Storage SAN768B and IBM System

Storage SAN384B can be expandable platforms for intelli-

gent, policy-driven services that can help manage and protect

your enterprise data in virtualized environments. The

SAN768B and SAN384B backbones utilize Brocade Fabric

OS (FOS), which provides several characteristic features,

including Bottleneck Detection, Top Talkers (part of

Advanced Performance Monitoring), and Adaptive

Networking, a suite of tools that includes Ingress RateLimiting, Traffic Isolation and quality of service (QoS).

Managed through IBM System Storage Data Center Fabric

Manager (DCFM) or the command line interface (CLI),

these advanced capabilities help optimize fabric behavior andapplication performance.

QoS and traffic management applications help ensure that

application workloads meet service levels if congestion occurs

anywhere in the data path. Resource recovery applications

can detect stranded resources or inefficiently used resources,

and reclaim or reallocate them to optimize data flow accord-

ing to predefined policies. For example:

● Bottleneck Detection identifies and alerts administrators to

ISL or device congestion as well as device latency condi-

tions in the fabric. These conditions can cause latency andI/O timeouts if left undetected and unresolved, particularly

in highly virtualized server environments.● Top Talkers measures the top bandwidth-consuming traffic

(including by individual virtual machine) in real time over a

physical device connection or throughout a network switch.

Premier platform for data center connectivity

System Storage

● Ingress Rate Limiting restricts data flow from less-critical

hosts at preset bandwidths.● Traffic Isolation dedicates paths in the fabric to specific

data flows, enabling predictability and avoiding network

congestion.● QoS expedites critical traffic in the event of congestion

while keeping all traffic flowing.

Virtual Fabrics The IBM System Storage SAN768B and the IBM System

Storage SAN384B support the ANSI standard-based imple-

mentation of Virtual Fabrics (VF). Virtual Fabrics adds the

capability for physical switches to be partitioned into inde-

pendently managed logical switches, each with its own data,

control, and management paths. Logical switches can be used

to allocate fabric resources on a per-port basis rather than ona per-switch basis. Additionally, logical switches can simplify

resource allocation by customer, department, application or

storage tier, and consolidate resources across multiple fabrics.

Each logical switch belongs to one logical fabric. A logical

fabric can include both logical and physical switches. Physical

switches joining a logical fabric are not required to support

the Virtual Fabric feature, making it compatible with existing

fabrics. All fabric services, such as Zoning, QoS and Access

Control List (ACL) policies are managed separately in each

logical fabric. Virtual Fabrics enable improved ISL bandwidth

utilization, per-port resource allocation and flexible manage-

ment partitioning, which can result in reduced power and

cooling costs, more ports for connectivity to end devices, and

a simplified management scheme.

Investment protection and efficiency To help enterprises protect their technology investments, the

SAN768B and the SAN384B feature backward compatibility

with IBM b-type and m-type fabrics, as well as interoperabil-

ity with other fabrics. The SAN768B and SAN384B can con-

nect to IBM TotalStorage® SAN256B, IBM TotalStorage

SAN140M and IBM TotalStorage SAN256M directors and

also to b-type and m-type switches and routers. By adopting

an evolutionary strategy rather than a “rip-and-replace”

approach, enterprises can save significant time, money andeffort as they move forward while minimizing disruption

and risk.

The SAN768B and SAN384B are high-performance, highly

efficient platforms, in terms of watts per gigabit per second of

bandwidth. They require significantly less power to deliver

much greater bandwidth, which helps make them consider-

ably more cost-effective than previous alternatives.

Data Sheet

System Storage

As a 512-port end user backbone solution, the SAN768B

backbone with 8 Gbps SFPs delivers extremely high perform-

ance per chassis. It requires significantly less power to deliver

much greater bandwidth than the 4 Gbps SAN256M director

and the 4 Gbps SAN256B director.

For a 256-port end user backbone solution, the SAN384B

backbone with 8 Gbps SFPs delivers higher performance per

chassis, requiring less power to deliver much greater band-

width than the 4 Gbps SAN256B director.

Plug-in security and disaster recovery

solutions The IBM System Storage b-type director family enables

scalable, high-performance, and cost-effective security and

disaster recovery solutions through plug-in blades. TheEncryption Blade can encrypt data-at-rest at up to 96 Gbps

per blade (up to four blades can be installed per chassis) with

highly secure 256-bit AES and integrated support for

IBM Tivoli® Key Lifecycle Manager (TKLM). The

Extension Blade extends replication and backup over

IP WAN links with high performance 10 Gbps FCIP

connectivity.

Technical capabilitiesEach IBM System Storage SAN768B and IBM System

Storage SAN384B contains redundant control processor

modules (active/standby) and core blades (active/active), plus

slots for FC port blades and advanced functionality blades.

All Fibre Channel ports on the blades support full-duplex,

non-blocking performance. A base system does not include

any port blades; at least one blade is required for host, stor-

age and SAN connectivity.

Available blades for the SAN768B and SAN384B include:

● 8 Gbps 16-port, 32-port, 48-port and 64-port FC blades● 8 Gbps 16-port FC encryption blade● 10 Gbps six-port FC blade● FCoE 10 GbE 24-port blade supporting twenty-four

10 Gbps CEE/FCoE ports● 8 Gbps extension blade supporting twelve 8 Gbps FC ports

and ten 1 Gbps GbE ports, or two optional 10 Gbps GbE

ports

Compact platform for enhanced data center connectivity

System Storage

Each SAN768B and SAN384B features ultra-high-speed

Inter-Chassis Link (ICL) ports to connect up to three back-

bones, providing extensive scalability and flexibility at the

network core without using any Fibre Channel ports.

The optional Inter-Chassis Cable Kit and either the

Inter-Chassis License or the Inter-Chassis Links, Half

features enable connections between SAN768B and

SAN384B (both systems must have the Inter-Chassis Cable

Kit and either the Inter-Chassis License or Inter-Chassis

License, Half optional features).

Each ICL port on the SAN768B provides 16 8 Gbps

trunked ISL connections, while the SAN384B provides

8 8 Gbps trunked ISL connections.

● Total ICL bandwidth between SAN768B chassis is

512 Gbps and preserves sixty-four 8 Gbps ports for server,

storage and switch connections.● Connecting three SAN768B chassis yields 1536 universal

FC ports with 12.288 Tbps aggregate bandwidth.● Total ICL bandwidth between SAN384B chassis is

256 Gbps and preserves 32 Gbps ports for server, storage

and switch connections.● Connecting three SAN384B chassis yields 768 universal FC

ports with 6.144 Tbps aggregate bandwidth.● All backbones connected via ICLs must be mounted in the

same cabinet or in adjacent cabinets.●

ICL bandwidth load balanced across 8 8 Gbps frame-based trunk groups using Dynamic Path Selection.

Fibre Channel ports use an optical transceiver to convert

electrical signals to optical pulses and optical pulses back to

electrical signals. Each 8 Gbps port blade requires either an

8/4/2 Gbps SFP+ or 4/2/1 Gbps SFP optical transceivers. All

8 Gbps ports are capable of automatically negotiating to the

highest speed supported by the attached server, storage sys-

tem, director, switch or router.

The FCoE ports require a 10 Gbps SFP optical transceiver.

Each 1 Gbps FCIP port can use either an SFP optical trans-

ceiver (1 Gbps and 10 Gbps) or a copper transceiver, while

the 10 Gbps FCIP ports require SFP optical transceivers.

Each 10 Gbps FC port requires an XFP optical transceiver.

All 8 Gbps port blades support the following Fibre Channel

port types: FL_Port, F_Port, M_Port (Mirror Port), E_Port,

EX_Port (Fibre Channel Integrated Routing). Fibre

Connectivity (FICON®) is supported on 16-port and 32-port

blades and on 48-port blades as part of a logical switch con-

figuration using Virtual Fabrics. FICON is not supported on

the 64-port blade.

The 8 Gbps 16-port FC encryption blade is a high-speed,

highly reliable hardware device designed to deliver fabric-

based encryption services to secure data assets either selec-

tively or on a comprehensive basis. It provides up to 96 Gbps

of encryption processing for disk and 48 Gbps of compres-

sion and encryption processing for tape. Up to four bladescan be installed in a chassis, yielding up to 384 Gbps for disk

and 192 Gbps for tape per chassis. The encryption blade can

be easily deployed in existing fabrics with minimal risk and

disruption.

Redundant and hot-swappable power supplies and fans help

maximize availability and simplify serviceability. The

SAN768B Power Supply Upgrade provides two additional

power supplies.

The SAN768B and SAN384B are supported only in an

IBM TotalStorage SAN Cabinet (2109-C36). Up to two

SAN768Bs or three SAN384Bs can be installed in one

cabinet.

Fabric operating system and

management softwareBrocade Fabric OS (FOS) is included with each System

Storage SAN768B and System Storage SAN384B, and it con-

tains all functions necessary to operate a base system. The

FOS level required may vary depending on the featuresselected. The SAN768B and SAN384B systems with

Encryption Blade require Tivoli Key Lifecycle Manager

(TKLM) v.2.0 or later. FOS offers the following advanced

functions (either included in the base switch or as optional

features).

Advanced FOS functionality includes:

● Adaptive networking services is a set of features that pro-

vides users with tools and capabilities for incorporating

network policies to ensure optimal behavior of a large SAN.

It uses network intelligence to anticipate congestion and todynamically make adjustments in the fabric so that applica-

tion traffic continues to flow.● Advanced performance monitoring helps identify end-to-

end bandwidth usage by host/target pairs and is designed

to provide for capacity planning.● Advanced Web tools enables GUI-based administration,

configuration and maintenance of a SAN switch.● Advanced zoning partitions a SAN into logical groups

(called zones) to restrict device communication and apply

certain policies only to members within the same zone.

● Enhanced group management (EGM) enables additional

device-level management functionality for IBM b-type

SAN products when added to the element management and

also allows large consolidated operations to groups of

devices (such as firmware downloads and configuration

uploads and downloads).● Extended fabric extends SAN fabrics beyond the Fibre

Channel standard of 10 km by optimizing internal switch

buffers to maintain performance on ISLs connected at

extended distances.● Fabric watch constantly monitors mission-critical switch

operations for potential faults and automatically alerts

administrators to problems before they become costly

failures.● FICON with CUP activation is designed to provide in-

band management of the SAN768B and SAN384B by

System Automation for z/OS® from IBM System z9® EC

and zSeries® 990 and 900 servers. This support is designed

to provide a single point of control for managing connec-

tivity in active FICON I/O configurations.● Integrated routing allows any FC port in a backbone to be

configured as an EX_Port to support Fibre Channel (FC)

routing.● ISL trunking enables FC packets to be distributed effi-

ciently across multiple ISLs between two IBM b-type SAN

fabric switches and directors while preserving in-order

delivery. Both b-type SAN devices must have trunking

activated.● Server Application Optimization (SAO) isolates and pri-

oritizes individual Virtual Machine data flow for end-to-end

QoS, preserving individual SLAs from each VM through

the SAN.● Virtual fabrics allow a physical switch to be partitioned

into independently managed logical switches, each with its

own data, control and management paths.

System Storage

Optional advanced SAN Extension functionality includes:

● 8 Gbps advanced extension enables two features: FCIP

Trunking and Adaptive Rate Limiting (ARL). FCIP

Trunking allows multiple IP source and destination address

pairs (defined as FCIP circuits) via multiple interfaces to

provide a high-bandwidth FCIP tunnel and failover

resiliency. Up to four IP source and destination pairs are

supported in FOS V6.3. The Adaptive Rate Limiting fea-

ture provides a minimum bandwidth guarantee for each

tunnel with full utilization of the available network band-

width without affecting throughput performance under

high traffic load.● 8 Gbps extension blade 10 GbE activation enables up to

two 10 GbE ports on the 8 Gbps Extension Blade. With

this license, two additional operating modes, in addition to

1 GbE port mode, can be selected. Either two 10 GbE

ports, or ten 1 GbE and one 10 GbE ports, can be config-

ured on an 8 Gbps Extension Blade. One license applies for

each 8 Gbps Extension Blade.● 8 Gbps advanced FICON accelerator employs emulation

techniques to reduce or eliminate performance degradation

over extended distances for applications such as

IBM z/OS Global Mirror and remote tape. Benefits include

improved FICON read and write performance, which

allows faster data backup and recovery operations.

Optional advanced SAN Encryption functionality includes:

● Sixteen auto-sensing 8 Gbps Fibre Channel ports with

cryptography (encryption/decryption) and data compression

capabilities● Fabric-based data-at-rest encryption for disk array LUNs,

heterogeneous tape drives, and virtual tape libraries to

enforce data confidentiality and privacy requirements● Easy integration, forward and backward compatibility with

IBM b-type and m-type fabrics● Up to 96 Gbps per blade of encryption processing to sup-

port heterogeneous enterprise data centers● Up to 48 Gbps per blade of compression processing for

tape storage systems● Frame Redirection technology that enables easy, non-

intrusive deployment of fabric-based security services● Plug-in encryption services available to all host servers,

including virtual machines, attached to data center fabrics● Support for IBM Tivoli Key Lifecycle Manager for both

disk and tape encryption applications

IBM System Storage Data Center Fabric Manager (DCFM)

is a software program that centralizes management of data

center fabrics, maximizes productivity by automating tasks,

provides an intuitive GUI-based interface with wizard-driver

operations, and actively monitors mission-critical fabrics in

real time. DCFM is recommended as the preferred network

management program.
