System connections
You must install a host bus adapter or host channel adapter in the host system.
Installing a host bus adapter or host channel adapter in the host
system
Host bus adapters (HBAs) provide an interface from the host system’s PCI bus to Fibre Channel-attached
devices. Host channel adapters (HCAs) provide an interface from the server’s PCI bus to InfiniBand
devices.
IBM FlashSystem 710 User’s Guide 3

Ensure that the adapter that you select for use with the storage system provides a driver for the
operating system version that you are using.
Note: In subsequent sections, the term HBA is used to represent HCA or HBA interchangeably.
Before you install the HBA, consult your server documentation to determine which one of its PCI slots is
on the fastest and least congested PCI bus. Follow the instructions that are provided with the HBA to
install the card and driver. Obtain the latest drivers and firmware for the HBA. Updated drivers might
include new functions, improved performance, and minor bug fixes.
The speed of the server and network interface ultimately determine the storage system's capabilities.
Some components that can affect the maximum performance of the storage system include FC or
InfiniBand interfaces, host bus adapters, PCI buses, and server processor resources.
Fibre Channel interface bandwidth
Your storage system supports Fibre Channel (FC) communication speeds of 2 Gbps, 4 Gbps, or 8 Gbps.
Accounting for encoding and overhead, the maximum 8 Gbps transfer rate allows data to be transmitted
to the system at a half duplex rate of approximately 800 MBps. Fibre Channel interfaces have separate
read and write connections that allow a maximum data rate of twice the half-duplex rate. To sustain the
maximum full duplex rate, the data usage pattern of the system must be 50% read and 50% write. This
requirement is because of the individual half duplex limits. To find the maximum for other data usage
patterns, use the following formula (given an 8 Gb HBA):
[(smaller usage percentage/larger percentage) ×800 MBps] + 800 MBps
For example, to calculate a data usage pattern with 66% reads and 33% writes,
[(33/66) ×800] + 800 = 1200 MBps
Many applications require storage bandwidth that exceeds what a single FC connection can provide. To
accommodate this situation, up to 4 FC ports are available per system, each of which can supply the
bandwidth described here. Using multiple FC connections requires one of the following solutions:
multipathing software to a single logical unit, using software to stripe across multiple logical units,
accessing multiple logical units concurrently, or connecting multiple servers to the storage system.
Host bus adapter settings
You can modify some host bus adapter (HBA) settings to increase performance.
For information specific to your HBA, consult the HBA documentation. Many settings are intended to
increase the performance of slow storage devices and are not applicable to this high performance system.
In particular, it is always advisable to check the frame size. The amount of overhead for each Fibre
Channel frame is fixed, so larger frames have lower overhead. Set the frame size to the maximum setting,
generally 2048 bytes. For InfiniBand devices, also set the frame size to the maximum setting, generally
4096 bytes.
PCI bus selection and performance
High-bandwidth host bus adapter (HBA) traffic can quickly inundate slower PCI buses. When a PCI bus
reaches its limit, you can do little to improve performance.
Many servers, however, provide different PCI buses with different speeds, and placing the HBA on a
faster PCI bus can improve performance. When you install an 8 Gb, 2-port HBA in the server, allocate at
least an entire PCI-X bus or a PCI Express (PCIe) slot.
4IBM FlashSystem 710: User's Guide

Processor performance factors
At a certain point, processor performance can limit data transfer rates. Determine whether the server’s
processor resources are the limiting factor in performance while you benchmark the storage system as a
raw physical device.
Otherwise, an improperly tuned file system or application can make the processor seem to be the limiting
factor when it is not. Complete raw device testing after you set up any multipathing.
There are a few ways to decrease processor usage without increasing processor resources. Certain data
usage patterns can be processor-intensive and fully use the processor. These usually involve small
transfer sizes. When possible, increasing the average transfer size decreases processor usage and offers
better performance.
Another way to decrease processor usage is by enabling interrupt coalescing. Interrupt coalescing is an
HBA-dependent function that decreases processor usage at the expense of latency. This function delays
the calling of the HBA transfer interrupt until several transfers are ready. However, in general, do not
enable interrupt coalescing because the storage system performance benefits from low latency. For more
information, see your HBA documentation.
Connecting the Fibre Channel or InfiniBand ports
Connect the Fibre Channel (FC) ports on the storage system to your server or to an FC switch. If your
storage system has InfiniBand ports, connect them to an InfiniBand switch or host channel adapter (HCA)
in your server.
The following figure shows the port layout for the storage system. Each controller has two FC ports: A
and B, on the left and right respectively. The FC ports on the system can connect to Point-to-Point
(N-Port), Arbitrated Loop (NL-port), or Switched Fabric (F-Port) topologies at 2 Gb, 4 Gb, or 8 Gb speeds.
Although Figure 1 shows FC controller cards, an InfiniBand controller card can occupy either of the same
slots as the FC controller cards. The InfiniBand controller card has two x4 InfiniBand ports: A and B, on
the top and bottom respectively. The InfiniBand ports can connect to Quad Data Rate (QDR), Double
Data Rate (DDR), or Single Data Rate (SDR) HCAs. This connection uses the Small Computer System
Interface (SCSI) remote direct memory access (RDMA) Protocol (SRP).
vOn an FC controller card, the FC port LED is green if the speed is set to 8 Gb. If the speed is set to 4
Gb, the LED for the FC port is amber.
vOn an InfiniBand controller card, the port LED is green when the link is established.
Connecting the system to a management network
Your system includes a Gigabit Ethernet management controller port (MCP) connection for remote
management over a network.
You use this connection to configure the system's storage and management functions.
Figure 1. Fibre Channel or InfiniBand port locations
IBM FlashSystem 710 User’s Guide 5

Connect the Ethernet MCP to the network.
Connecting power to the system
Although the system operates when only one power supply is connected, this set up is not
recommended.
Using the ac power cords that are provided, connect each power supply to a power source. As a best
practice, connect each of the power cords to separate circuits.
