IBM TotalStorage SMB solutions
The IBM TotalStorage® SAN32M-2 fabric switch is designed specifically to
address the needs of medium-sized
and enterprise SAN environments. It
can be used to create a wide range of
high performance SAN solutions, from
simple single-switch configurations to
larger multi-switch configurations which
support fabric connectivity and
advanced business continuity
capabilities. Infrastructure simplification
solutions for IBM _`® xSeries®,
iSeries™, pSeries® and zSeries®
servers include storage consolidation
and high-availability server clustering
with IBM TotalStorage disk storage
arrays. Business continuity solutions
include data protection with
IBM TotalStorage tape libraries and
devices, and IBM Tivoli® Storage
Manager data protection software.
A single SAN32M-2 switch can serve
as the cornerstone of a Storage Area
Network for those who want the benefits of storage consolidation and are just
beginning to implement Fibre Channel
storage systems. Such an entry-level
High density design with 32 ports in an efficient 1RU height helps save rack space
configuration can consist of one or two
Fibre Channel links to a disk storage
array or to an LTO™ tape drive. An
entry-level, 16-port storage consolidation solution can support up to
15 servers with a single path to either
disk or tape. The FlexPort feature is
designed to enable a base switch to
grow to 16 ports, in eight port increments, to support more servers and
more storage devices without taking
the switch offline.
A high-availability solution can be created with redundant switches. This
capability is ideal for server clustering
environments. Such a configuration can
support from 14 to 30 servers, each
with dual Fibre Channel adapters crossconnected to redundant SAN32M-2
switches which are cross-connected to
a dual-controller storage system.
While the SAN32M-2 can be the foundation of medium-sized SANs, it can be
configured to participate as a full member in a tier enterprise SAN with other
members of the IBM TotalStorage SAN
m-type family. This capability helps provide investment protection as SAN
requirements evolve and grow over
time.
Simple SAN configuration
The introduction of large capacity, highavailability storage systems offers new
opportunities for cost reduction through
storage consolidation and infrastructure, and management simplification. In
older environments each server
accessed its own dedicated storage
capacity using either internal disks that
were contained within the server, or
disks which were part of an external
system attached exclusively to that
server. It has become difficult to sustain
that approach as both the requirement
for storage capacity and the number of
servers has increased. Storage consolidation is a fundamental objective of
infrastructure simplification and is based
on the philosophy that it is easiest to
share and manage capacity contained
in a large capacity, high-performance
and high-availability external storage
system such as provided by the
IBM TotalStorage DS4000 and DS6000
series. Fibre Channel Storage Area
Networks (SANs) were developed to
provide efficient, high-performance
access from many servers to many
storage devices.
While it is possible in small environments to direct-connect servers to
external storage systems using fibre
channel links, it is more common to
configure a SAN switch between the
servers and the storage system to
enable multiple servers to share the
same storage capacity. This simple
SAN is depicted in the following
diagram.
The SAN32M-2 was designed specifically for use as the SAN switch in this
type of configuration. It is easy to install
and easy to manage. The tan, green
and blue servers represent heterogeneous server types which are members
of the same SAN and share capacity of
the large disk system. The SAN32M-2
can be upgraded to 32 ports and is
future-ready to support 4 Gbps servers
and storage devices as they are introduced. Its flexible design allows participation with other SAN m-type switches
in fabrics that evolve as requirements
change. And it supports advanced
functions to help enable participation in
complex fabrics including cascaded
switches and ISL trunks.
High availability SAN configuration
Many applications require continuous
operation. A common design approach
to achieve that objective is to run multiple instances of the application across
a cluster of servers. When a server fails
or must be taken offline for maintenance, a backup server is available to
help continue operation with a minimum
of impact. Redundant paths to data are
usually configured in a clustered server
environment for the same reasons in an
effort to help maintain access to data.
Each server is configured with redundant Host Bus Adapters. Each Host
Bus Adapter is connected to a different
SAN switch, and each switch is connected to a different controller in a disk
system. Every effort is made to maintain
application access to data.
The SAN32M-2 is an excellent switch
to use in a clustered server environment. Separate SAN switches enable
two separate SAN fabrics, which are
desirable as a means to help minimize
or eliminate single points of failure. The
yellow and green clusters shown above
provide redundant components at every
level and are designed to help minimize
application outages.
Business continuity solution
Many small- and medium-sized companies want to implement a business continuity or remote backup capability to
help address strict new regulatory
requirements. The SAN32M-2 fabric
switch can help provide the SAN connectivity required for these environments. The diagram on the following
page is intended to represent two different sites. The blue side represents
the production site and the green side
represents the remote or backup site.
Many disk subsystems, including the
IBM TotalStorage DS6000 and DS4000
series, are capable of copying data to a
remote location. The data path for the
remote copy operation is represented
by the red links in the diagram.
Two SAN32M-2 fabric switches can be
connected over metro distances (up to
10 km) using longwave SFP optical
transceivers. Longer distances can be
supported with SAN routers, such as
the IBM TotalStorage SAN04M-R and
SAN16M-R, which transport Fibre
Channel Protocol (FCP) over Internet
Protocol (IP) networks without merging
the local and remote fabrics.
SAN32M-2 fabric switches can also be
used to connect two locations to
enable remote data backup. An
Information Lifecycle Management (ILM)
application such as IBM Tivoli® Storage
Manager (TSM), which runs on a server
in the production site, can write data to
a tape system at a remote location. The
same distance capabilities are available
for the business continuity solution
described above.
First time SAN users characteristics
Easy to install and maintain
The SAN32M-2 includes capabilities
designed to make it easy to install and
easy to maintain for system administrators who have minimal experience with
SAN components. EFCM Basic provides intuitive graphic switch management capabilities. Installation and
backup/restore wizards are included for
novice users which are designed to
help guide them through switch setup
and operation.
EFMC Basic (formerly SANpilot) is
designed for first-time SAN users with
minimum SAN expertise. EFCM Basic
can help simplify monitoring and configuration management. Functions include
Web browser access, fabric and switch
configuration management, port activity
monitoring and reset, firmware updating, event logging, diagnostics and
online help. Whether you have a single
switch or a small fabric to manage,
EFCM Basic capabilities and functionality can help simplify management of
your SAN solution.
Pay-as-you-grow scalability
The FlexPort Expansion feature is
designed to support scalable switch
upgrades. The FlexPort feature provides
an activation key and eight shortwave
SFPs which upgrade the switch in
eight-port increments while helping
avoid fabric disruption. The ability to
increase switch capacity while maintaining service helps customers implement
a pay-as-you-grow strategy while minimizing impact to applications.
High performance
The SAN32M-2 switch provides 4 Gbps
performance on all ports when paired
with storage system hardware that supports 4 Gbps throughput. Each port
auto-negotiates to 4, 2 Gbps or
1 Gbps, full duplex, depending on the
capabilities of the attached device or
switch. Up to 256 Gbps aggregate
throughput is possible with 32-port
configurations.
Network performance can be enhanced
with the Open Trunking feature which
automatically balances performance
throughout a network while helping
minimize storage administrators’
involvement. Open Trunking is designed
to optimize the total throughput
between two switches automatically by
redirecting traffic from high-utilization
links to links with available bandwidth.
Open Trunking is designed to continuously monitor loads on all links, detect
congestion and automatically balance
traffic across available ISLs without
operator interaction. Based on constant
traffic monitoring, Open Trunking acts
to help improve throughput and reroute
traffic efficiently.
High-availability
Medium-sized and enterprise businesses require high-availability switch
fabric solutions. The SAN32M-2 fabric
switch uses advanced applicationspecific integrated circuits (ASICs) to
help minimize the number of internal
components and thus improve reliability.
The SAN32M-2 switch is designed to
provide hot-swappable, load-sharing
dual power supplies designed to allow
the switch to remain online if one power
supply fails. Dual power cords allow
attachment to separate power sources
to help improve availability. Hotswappable power supplies with integrated cooling components help eliminate downtime for service when
replacing a failed component and help
reduce or eliminate the risk of erroneously cabling a replacement switch
because of a simple component failure.
Failed power supplies require IBM service or switch replacement and hotpluggable optical transceivers can be
replaced without taking the switch
offline.
FlexPort technology is designed to
support switch port upgrades without
fabric disruption. In addition, HotCAT
online code activation is designed to
allow firmware to be downloaded and
activated while the fabric switch
remains operational. Redundant
switches can be deployed for highavailability clustering applications.
Advanced solution management
Enterprise Fabric Connectivity
Manager
Enterprise Fabric Connectivity Manager
(EFCM) software is designed to
support interconnection of multiple
IBM TotalStorage SAN m-type switches
and directors for the creation of tiered
enterprise SAN solutions. EFCM software with a 1U rack mount management server (separately orderable
products) is designed to centralize the
management of multiple, distributed
switches and directors in an enterprisewide Fibre Channel fabric.
The SAN32M-2 Element Manager
feature is designed to enable tiered
enterprise-to-edge EFCM management
of SAN32M-2 switches when interconnected with multiple IBM TotalStorage
SAN m-type switches and directors in a
tiered enterprise SAN solution.
Open System Management Server
(OSMS), a standard feature, is an ANSI
(American National Standards Institute)based capability that supports SAN
management software from vendors
such as VERITAS, Tivoli and BMC.
OSMS is designed to extend the
switch’s capability to include in-band
management with an open systems,
host-based application and to allow
the fabric switch and devices attached
to it to be “discovered,” or seen in a
fabric through a framework software
application.
SANtegrity™ Enhanced (Security
Suite) feature is designed to help
enhance business continuity by reducing the impact of human influences on
networked data. The feature includes
SANtegrity Binding and SANtegrity
Authentication.
SANtegrity Zoning, a standard capability of Enterprise Operating System
(E/OS), provides hardware-enforced
world wide name (WWN) and port zoning. SANtegrity Secure Management
Zone (SMZ) is designed to secure management access to local and remote
SAN devices over a secure connection.
SANtegrity Binding is designed to create multiple layers of access control,
including port, switch and fabric
binding.
Standards-based SANtegrity
Authentication is designed to force
each device in the SAN to prove who
they are in order to avoid unauthorized
access and unauthenticated devices.
Preferred Path, a standard feature, is
designed to allow a customer to define
routes across a fabric. The Preferred
Path modifies the behavior of Open
Trunking by providing guidance for the
balancing function. The Preferred Path
configuration helps address user preference regarding exit port assignment but
is subject to the standard rules regarding the Fabric Shortest Path First
(FSPF) protocol.
Full Volatility feature is designed to
support high-security environments,
which require no customer data be
retained after power-off. Full Volatility is
designed to configure a switch or director so that no frame data is stored after
a power-off.
SAN32M-2 FICON® Management
Server feature supports management of
the SAN32M-2 switch using System
Automation for z/OS and System
Automation for OS/390® and zSeries
900 servers. IBM 9032 ESCON®
director is a type of dynamic in-band
management. System Automation—for
z/OS or OS/390—is designed to concurrently manage IBM 9032 ESCON
directors as well as McDATA® FICON
directors.
High port density, rack space savings
Rapidly growing Fibre Channel SAN
infrastructures place a premium on rack
space. The IBM TotalStorage
SAN32M-2 fabric switch uses SFP LC
optical connectors and advanced packaging that requires only one-rack unit
(1U) height for 32 ports. The
SAN32M-2 switch is also tabletop
stackable.
