Chapter 1 – ntroduction
1.1 Overview
The RamSan-500 is the World’s Fastest Flash-based storage system. The
basic unit contains nine RAID-protected Flash storage modules accessible
from the front, with a combined usable capacity of either 1 or 2-Terabytes
and a data bandwidth of 2 GB/sec. A single RamSan-500 fits in 4U of rack
space. Multiple RamSan-500 units scale capacity, bandwidth, and IOPS.

Unlike other mass storage products, the RamSan-500 is not based on
mechanical rotating disk technology, but instead on high performance
memory technology. While each of the nine Flash storage modules may
look like a disk, there are no moving parts and it operates with a much
faster protocol, reducing access time and increasing the data transfer rate.
This is achieved with the use of better connectors (rugged, more data
pins) and a simple transfer protocol.
While the capacity and throughput of the RamSan-500 is impressive, the
key to the system’s power resides in its I/O structure. The RamSan-500
can be configured with 2-8 Fibre hannel (F ) ports. Internally, it can
handle the bandwidth and supply the IOPS needed for emerging storage
applications.

RamSan-500 User’s Man al 5 of 48
1.4 Reliability
The RamSan-500 is designed to offer superior reliability to other solid-
state disks and RAID devices. Its standard features include hipkill™-
protected RAM, hot-swap modular Flash memory, hot-swap power
supplies, failover ports, and SNMP compatibility. The nine-unit RAID
design ensures data integrity even in the event of the complete failure of
a single Flash module. In order to reduce the probability of a Flash module
failure, the unit incorporates multiple error-correcting methods.
1.5 System Management
Basic management operations, including manual shutdown and alerts, are
available from the front panel screen. Full monitoring and configuration
capabilities are available over any browser via a password protected Java
applet. The RamSan-500 also offers Telnet management capabilities and
is fully SNMP compatible.

2.2 System Overview
All nine Flash storage modules can be quickly accessed from the front
of the RamSan-500. Each module has an interlocking system with the
look and feel of a typical disk drive. The Flash module can be removed
while system power is on, once the module has been selected to go
off-line (indicated when both module LEDs are off). Additionally, all
nine Flash modules can be removed and reinstalled into another
RamSan-500 unit.

Chapter 3 – Connections
3.1 nstalling a Host Bus Adaptor in the Host System
Host Bus Adapters (HBAs) provide an interface from the server’s P I bus
to Fibre hannel attached devices. HBAs are available from a variety of
vendors. Before purchasing an HBA, ensure that it provides a driver for
the Operating System (OS) version that you are using.
Before installing the HBA, consult your server’s documentation to
determine which one of its P I slots is on the fastest and least congested
P I bus (see Section 3.1.3, below, for details). Next, power down your
server and place the HBA in this slot. Power on your server and follow the
instructions provided with the HBA to install the driver. It is generally a
good idea to check the HBA provider’s Web site to obtain the latest drivers
and firmware for the HBA. Updated drivers may include new features,
improved performance, and minor bug fixes.
T ROUBL SHOOTING T IP :
I F YOU EN OUNTER ANY PROBLEMS WITH THE HBA, THE FIRST STEP IN THE DEBUGGING
PRO ESS IS VERIFYING THAT YOU ARE USING THE LATEST DRIVER AND FIRMWARE .
The speed of the server and network interface ultimately limit the
RamSan-500’s capabilities. A few different components can affect the
maximum performance of the RamSan-500, including F interfaces, Host
Bus Adapters, P I buses, and server PU resources.

urrently, the RamSan supports two Fibre hannel communication
speeds: 2- and 4-gigabit. Accounting for encoding and overhead, these
transfer rates allow data to be transmitted to the RamSan-500 at a
half duplex rate of ~200 MB/s and ~400 MB/s, for 2- and 4-gigabit,
respectively. Fibre hannel 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 (due to the individual
half duplex limits). To find the maximum for other data usage patterns,
use the following formula (4-gigabit HBA):
( Smaller usage percentage / Larger ) x 400MB/s + 400MB/s
For example, to calculate a data usage pattern with 66% reads and
33% writes:
( 33 / 66 ) x 400 + 400 = 600 MB/s
Many applications require storage bandwidth that exceeds what a
single F connection can provide. To accommodate this situation, we
provide up to 8 F ports per RamSan-500, each of which can supply
the bandwidth described above. Using multiple Fibre hannel

RamSan-500 User’s Man al 9 of 48
connections requires one of the following solutions: multi-pathing
software to a single LUN, using software to stripe across multiple LUNs,
accessing multiple LUNs on the RamSan-500 concurrently, or
connecting multiple servers to the system.

You can modify some HBA settings to increase performance. For
information specific to your HBA, consult the HBA documentation. Note
that many settings are intended to increase the performance of slow
storage devices and will not be applicable to RamSans. It is always
advisable to check the frame size. The amount of overhead for each
Fibre hannel frame is fixed, so larger frames have lower overhead.
Set the frame size to the maximum setting, generally 2048 bytes.

High bandwidth HBA traffic can quickly inundate slower P I buses.
Once a P I bus reaches its limit, you can do very little to improve
performance. Many servers, however, provide different P I buses with
different speeds, and placing the HBA on a different P I bus can
improve performance. TMS recommends giving each 4-gigabit 2 port
HBA at least an entire P IX bus or a P I Express (P Ie) slot.

PUPU
PU
At a certain point, PU performance can limit data transfer rates.
Determine whether the server’s PU resources are the limiting factor
in performance while benchmarking the RamSan-500 as a raw physical
device. Otherwise, an improperly tuned file system or application can
make the PU appear to be the limiting factor when it is not. Perform
raw device testing after setting up any multi-pathing.
There are a few ways to decrease PU usage without increasing PU
resources. ertain data usage patterns can be very PU intensive and
fully utilize the PU. These usually involve small transfer sizes. When
possible, increasing the average transfer size decreases PU usage
and offers better performance. Another way to decrease PU usage is
by enabling interrupt coalescing. Interrupt coalescing is an HBA
dependent feature that offers a method to trade latency for PU usage.
This feature delays calling the HBA transfer interrupt until several
transfers are ready. In general, TMS does not recommend enabling
Interrupt oalescing, because most RamSan applications benefit from
low latency. For more information, consult your HBA documentation.
3.2 Connecting the Fibre Channel Ports
onnect the Fibre hannel ports on the RamSan-500 to your server or to
a Fibre hannel switch.

Figure 3– Fibre hannel Port Locations shows the port layout for the
RamSan-500. Each controller has two or four Fibre hannel ports: A and B,
on the top and bottom respectively. The F -77 ports on the system are
capable of connecting to point-to-point, arbitrated loop, and switched
fabric topologies at either 4-Gigabit or 2-Gigabit speeds.
3.3 Connecting to a Network
Your RamSan-500 includes a Gigabit Ethernet port for remote
management over a network. You use this connection to configure the
storage and management features.

Chapter 4 – Getting Started
This chapter will guide you through setting up your RamSan-500. It is
important to accomplish the following tasks to make your system usable:
 Use the front panel display to set up the network (Section 4. )
 Get the Web monitor operational (Section 4.7)
 Use the Web monitor to set the date and time (Section 4.8)
 Use the Web monitor to configure advanced network settings (Section
4.9)
 Use the Web monitor to configure security (Section 4.10)
Other sections explore the configuration tools and should be read to
familiarize you with the system.
4.1 Turning on the System
Separate power cables should be connected to each of the two RamSan-
500 power modules. The 3-prong A inlet lies at the bottom of each power
module. To power on the system, both power modules should be switched
on. Though the RamSan-500 will operate when only one power supply is
switched on, this is not recommended. After a user-initiated shutdown,
switch both power modules off, then switch both modules on again to
bring the system back on-line.
4.2 System nitialization
The front panel display shows the boot process’ current state. Once the
power is connected, the system turns on automatically and the front panel
display begins the power-on sequence. The following happens
automatically:
System Status: GOOD
1 2 3 4
 Once A power is connected, the
RamSan will power-up and the
front panel displays “System

performance bars for each Fibre
hannel port. The numbers
represent the Fibre hannel
ontrollers. If a controller is not
installed, the number and
corresponding performance will not
display. The top bars represent
port A and the bottom bars
represent port B.
The system is now ready for normal operation.
