PRELIMINARY DRAFT:Logical Network Configuration Chapter 2. Fibre
Channel Network
Logical Network ConfigurationThe Fibre Channel (FC) ports of a
IBM XIV Storage System are arranged with four ports in each
interface module. This section describes the connectivity options
available for the Fibre Channel network.
Note: Always check the latest version of the XIV
Interoperability Matrix to determine if a specific configuration is
supported.
Recommended High-availability ConfigurationThe optimal
high-availability configuration is illustrated in Figure 2-1.Figure
2-1 shows only an example, as all interface modules can be used in
this configuration,
The following guidelines apply to this configuration:• Each IBM
XIV Storage System module is connected to two FC switches, using
the
module's two ports.
• Each host is connected to two switches, using two HBAs (Host
Bus Adaptors), or an HBA with two ports.
This configuration assures full connectivity under single
failure of any individual component, as follows:• Upon switch
failure, each host remains connected to all modules, through
the
second switch.
• Should a module fail, each host remains connected to the other
two modules.
• Upon a FC switch replacement or software upgrade, the hosts
remain connected to the storage system.

Chapter 3. iSCSI Configuration
Physical Requirements
The IBM XIV Storage system is available in configurations:
Table 3-1 summarizes the currently available rack configurations
for iSCSI ports.
Three interface modules support iSCSI, with two ports in each
module.
This chapter applies to the full rack (15 module) system
only.
Logical Network Configuration
Logical network configurations for iSCSI are equivalent to
logical configurations suggested for FC networks. Four options are
available:
• High Availability: Each module is connected through two ports
to two different Ethernet switches, and each host is connected to
the two switches. This provides a network architecture resilient to
failure of any individual network switch or module.
• Single Switch Configuration: A single switch interconnects all
modules and hosts.
• Single Port Host Solution: Each host is connected to a single
switch, and a switch is connected to two modules.
• Direct connectivity to host connection: Each module is
connected directly to a host.

PRELIMINARY DRAFT:Ethernet Link Aggregation Chapter 3. iSCSI
Configuration
Ethernet Link AggregationIBM XIV Storage System supports the
configuration of Ethernet link aggregation, where two Ethernet
ports of the same module are connected to the same switch, and are
considered as one logical Ethernet port (including fail-over and
load balancing).
iSCSI Network Configuration
IP Configuration
Configuration of the IBM XIV Storage System iSCSI connection is
highly dependent on the customer's network. The two Ethernet
switches used for redundancy may be configured as either different
IP subnets or as part of the same subnet.IBM XIV Storage System
iSCSI configuration should match the user's network. The user
should provide the required configuration information for each
Ethernet port as follows:• The user must decide whether to
configure the two ports of each module as either
one logical Ethernet port (link aggregation) or two independent
Ethernet ports. This decision affects both how the system and
switch are configured.
• IP address • Net mask • MTU (optional)• Default gateway
(optional)MTU configuration is required if the user's network
supports an MTU which is larger then the standard one. The largest
possible MTU should be specified (it is advisable to use up to
9,000 bytes, if supported by the switches and routers).If the iSCSI
hosts reside on a different subnet than IBM XIV Storage System, a
default IP gateway per port should be specified.
Note: As IBM XIV Storage System always acts as a TCP server for
iSCSI connections, packets are always routed through the Ethernet
port from which the iSCSI connection was initiated. The default
gateways are required only if the hosts do not reside on the same
layer-2 subnet as the IBM XIV Storage System.
IP Network Configuration
IP network configuration should be ready to ensure connectivity
between the IBM XIV Storage System and the host, including the
following:• If required, Ethernet switches that connect to two
ports on the same module
should configure their ports as a link aggregation group (with a
parallel configuration on the IBM XIV Storage System module).
• Ethernet VLANs (if required) should be configured correctly to
enable access between hosts and the IBM XIV Storage System.
• IP Routers (if present) should be configured correctly to
enable access between hosts and the IBM XIV Storage System.

Chapter 4. Mixed iSCSI and FC Host Access
IBM XIV Storage System supports mixed concurrent access from the
same host to the same volumes through FC and iSCSI. When building
such a topology, you must plan carefully to properly ensure
redundancy and load balancing.
Please contact IBM XIV support if you want to configure both FC
and iSCSI access from the same host.
Notes: 1. Not all hosts support multi-path configuration between
the protocols.
2. In a partial rack (6 module) configuration, not all patch
panel interface ports are active.:
- Fiber Channel connections are active only for modules 4 and
5.- No iSCSI connections are active.

Chapter 6. Management Connectivity
Physical Management PortsIBM XIV Storage System is managed
through three IPs over Ethernet interfaces, in order to be
resilient to two hardware failures. Thus, the user should have
three Ethernet ports available for management. If you require
management to be resilient to a single network failure, it is
advised that you connect these ports to two different switches.Make
sure that the networking equipment providing the management
communication is UPS protected.
Management IP ConfigurationFor each of the three management
ports, the following configuration information should be provided
to XIV upon installation:• IP address of the port
• Net mask
• Default IP gateway
The following system-level IP information should be provided
(not port-specific):• IP address of the primary and secondary DNS
servers
• IP address or DNS names of the SNMP manager, if required
• IP addresses or DNS names of the SMTP servers
ProtocolsIBM XIV Storage System is managed through dedicated
management ports, running TCP/IP over Ethernet. Management is
carried out through the following protocols (please take this into
account when configuring firewalls, and other security protocols):•
Proprietary IBM XIV protocols are used to manage IBM XIV Storage
System from
the GUI and CLI. This management communication is performed over
TCP port 7778, where the GUI/CLI, as the client, always initiates
the connection and the IBM XIV Storage System performs as the
server.
• IBM XIV Storage System responds to SNMP management
packets.
• IBM XIV Storage System initiates SNMP packets when sending
traps to SNMP managers.
• IBM XIV Storage System initiates SMTP traffic when sending
e-mails (for either event notification via e-mail, or for
e-mail-to-SMS gateways).

Chapter 7. Remote Access and Call Home
Call Home ConnectionIBM XIV Call Home connects your system
directly to the IBM trouble?ticketing system, enabling both failure
and proactive, pre-failure notifications to be sent automatically
to IBM. When you enable Call Home support, the 2810 sends (via
email) an electronic call home record to IBM support when there is
a problem with the machine. When a problem requiring service is
received by IBM, a service representative is dispatched with the
necessary replacement parts. The Call Home alerts are sent by email
(SMTP), using the customer’s SMTP server. So in order to use this
capability, the 2810 must be configured to use an external SMTP
server, and be allowed to send messages to IBM using this server.
The configuration of the 2810 for Call Home is normally done when
the 2810 is first installed.
Remote Support ConnectionsIBM recognizes that there can be
instances in which the 2810 has detected problems that require IBM
service personnel to perform real-time problem analysis and
isolation. To address this possibility, IBM has designed a secure
network interface that allows authorized IBM personnel to access
the 2810 storage servers over a public network or over a telephone
modem connection. Remote-access support can help to greatly reduce
service costs and shorten repair times, which in turn lessens the
impact of any failures on your business. Remote access is supported
by either the modem feature (feature code 9101), or by using a
dedicated Ethernet connection to one or both of the VPN ports.
Remote Access by ModemTo use the modem for remote access, a
telephone line must be connected to the modem, and the telephone
number of the line provided to IBM. The 2810 does not make a
outgoing calls using the modem, so the telephone line need not
support dialing out.
Remote Access by Broadband ConnectionTo use a broadband
connection for remote access, the network connection must be made
to the VPN port connections on the patch panel. The VPN ports
should be connected through your organization's firewall so that
IBM XIV personnel can access the IBM XIV Storage System, if
required. Access can be limited to be from IBM XIV's IP address
space only. It is also possible to configure a VPN between IBM
XIV's offices and the organizational firewall, enabling access to
this port only through the defined VPN. The IBM XIV 2810 Storage
System only accepts connections on server port 22, and also uses
port 7778. The 2810 never uses these ports for outgoing IP traffic.
This connection is made by the two "VPN" ports on the patch panel.
The following configuration regarding the remote access port must
also be provided:• IP address of the remote access ("VPN")
ports.
• Network mask
• Default gateway
• External IP address (The IP address to which IBM support will
connect.)

Chapter 8. Laptop Port
The IBM XIV Storage System has two Ethernet laptop ports. These
ports should be used only by IBM service personnel. A single
laptop, or other computer, can be connected to these ports, and
once connected the system will serve as a DHCP server and will
automatically configure the laptop.Attention: These ports should be
used for direct laptop connections only, and must not be connected

Chapter 9. Rack Configurations
Racks can include multiple configurations from a minimum of six
(6) modules to a maximum of fifteen (15) modules. A rack containing
less than fifteen modules is considered a partially populated
system and a rack with fifteen modules is considered a fully
populated system.
Fully Populated Racks: 15 ModulesA fully populated rack contains
these modules:• 9 Data Modules
• 6 Interface Modules
• Total Number of DDMs: 180
Partially Populated RackPartially populated racks contain 6 to
14 modules (7 and 8 module configurations are not supported) Table
