GENERAL DESCRIPTION
PRODUCT DESCRIPTION
The Zeus
Cell (SLC) NAND flash memory technology to deliver a state-of-the-art, non-volatile mass storage
device. The interface is fully SCSI compliant and conforms to the same mechanical and mounting
requirements as a standard rotating disk drive. The SSD is an easy-to-install, drop-in replacement for
standard SCSI-compliant hard disk drives (HDDs). No additional device drivers are required to fully
support the drive as a boot or data storage device.
IOPS
3.5-inch Fibre Channel Solid State Drive (SSD) incorporates advanced Single-Level
FIBRE CHANNEL INTERFACE
The SSD can be installed in any operating system environment that supports FCP-4 devices. The
Fibre Channel Protocol (FCP) is a method for transmitting SCSI commands and data over FC-FS-2
Exchanges and Information Units. It is a high-speed serial architecture that allows for connections
over optical or electrical cable. It also supports fabric-switched and arbitrated-loop network
topologies.
DRIVE CAPACITIES
IOPS
Zeus
gigabytes. The SSDs are ideal for applications that require high reliability and high tolerance to
shock, vibration, humidity, altitude and temperature. Since there are no moving parts, the SSDs are
completely maintenance-free.
3.5-inch SSDs are available with unformatted memory capacities of 18, 36, 73 and 146
PERFORMANCE
The SSDs can operate at sustained data transfer rates of up to 200 megabytes per second. The
drives are capable of performing 50,000 random operations per second. Power consumption is kept
to a minimum; the SSDs can be powered from a single 12-volt source. The solid state design
eliminates electromechanical noise and delay inherent in traditional magnetic rotating media. The
wear-leveling and bad-block mapping algorithms ensure consistency, accuracy, and integrity of user
data. Superior data reliability is achieved through embedded Error Detection Code and Cyclic
Redundancy Checking (EDC/CRC).
DATA SECURITY

capacity of the drive. The drive can also be “sanitized”, thereby making data recovery impossible. See
Erase Times and Sanitize on page 10.
Zeus
SSDs offer erase and data sanitization (purge) features. Erase times vary according to the
IOPS
3.5-Inch Fibre Channel Solid State Drive Product Manual Rev. 1.0 23
PERFORMANCE CHARACTERISTICS
ENDURANCE
The useful life of the flash media is limited by the number of write/erase operations that can be
performed on the media. Typically, the write/erase cycles for flash media ranges between 100,000
and 300,000. To extend the life of the SSD, special Wear-Leveling and Bad-Block Mapping
algorithms are integrated into the firmware, increasing the overall endurance rating of the drive to
2,000,000 Write/Erase cycles.
WEAR-LEVELING ALGORITHM
The dynamic wear-leveling algorithm guarantees that erase/write cycles are evenly distributed
across all the flash memory block locations. Wear-leveling eliminates repeated writes to the same
physical flash memory location, thereby preventing blocks from premature wear.

The Error Detection Code and Error Correcting Code (EDC/ECC) algorithm helps maintain data
integrity by allowing single or multiple bit corrections to the data stored in the flash array. If the data
in the flash array is corrupted due to aging or during the programming process EDC/ECC will
compensate for the errors to ensure the delivery of accurate data to the host computer. The EDC/
ECC engine on the drive is capable of correcting 8 random or 12 sequential bytes in 1,024 bytes. The
possibility of undetected errors or incorrect correction is eliminated with additional CRC.

• Errors caused by host are excluded from rates.
• Errors from the same causes are counted as 1 block.

HOT PLUGGING
The Zeus
IOPS
3.5-inch Fibre Channel SSD can be inserted or removed from a loop during operation.
This capability is known as “hot plugging”. Fibre Channel error recovery procedures will recover from
any errors introduced by hot plugging. Whenever a drive is hot plugged, sync is detected lost due to
the removal or insertion of the drive into the loop.
The loop will recover as follows:
1 If a bypass circuit is used, the loop will re-synchronize and is operational while
the user waits for the drive to power up and become ready. If a bypass circuit is
not used, the loop loses synchronization and is not operational during this time.
2 When the drive becomes ready, and the bypass circuit (if used) is disabled, the
drive will re-synchronize with the loop. It will synchronize with the device that is
currently transmitting data to the SSD. All devices then go through loop
initialization.
3 After the loop initializes, the loop is in monitoring state and arbitration of
ownership can occur.
REPAIRS
A defective SSD should be replaced. There are no parts, assemblies or subassemblies that can be
repaired by the user. Please see the section titled Certification and Warranty on the inside of the

PREVENTATIVE MAINTENANCE
No preventative maintenance is required. The SSD unit is sealed at the factory, and there are no

POWER SUPPLY
The following voltage specification applies to the drive power connector. Connections to the drive
should be made in a safety extra low voltage (SELV) circuit.
The drive does not use the +5V supply input pins available on a typical 40-Pin SCA-2 connector.
The drive uses the +12V supply input. The 5V ground pins are connected to the common ground
plane within the unit.
Adequate secondary over-current protection must be incorporated in the host system (drive
enclosure, backplane, etc.). A 10 amp limit is required for safety purposes.
CAUTION: To avoid damage to the drive, power
supply voltage transients must not exceed 16
volts.

GROUNDING
Signal and chassis ground are not connected together in the drive. To ensure minimal EM emissions,
the user should provide maximum surface contact area when connecting the drive to chassis ground.
FAULT LED OUT SIGNAL
The Fault LED Out signal is driven by an open collector driver capable of sinking 30mA. It is driven
low when an internal fault is detected along with both Enable Bypass signals.
READY LED OUT SIGNAL
The Ready LED Out signal is driven by an open collector driver capable of sinking 30mA. It will
typically be connected to the cathode of an LED in the enclosure. The Ready LED function is nearly
identical to the SFF-8045 specification for hot-plugging implementations; however, since the drive
has no motor, it behaves as follows:
• Drive not mated:
The signal is de-asserted (i.e., High). The LED is off.
• Drive mated, power-up diagnostics in progress:
The signal is asserted for 1/3 of a second and de-asserted for 2/3 of a second. This
represents a 1Hz Short flash.
• Drive mated, firmware running, drive in progress of becoming ready:
The signal is asserted for one-half second and de-asserted for one-half second. This
represents a 1Hz Normal flash.
• Drive mated, firmware running and drive ready:
The signal is asserted when either of the loops is brought up. The signal will de-assert when
the drive is active on either of the fibre loops.
-PARALLEL ESI AND SEL_n/P_ESI_n
SEL_n/P_ESI_n are a set of dual purpose pins that are used to convey either a Loop Identifier
address or Enclosure Service Information (where this is supported by the backplane) to the SSD.
-Parallel ESI determines the function of Sel_n/-P_ESI_n. It is a TTL open-drain output from the SSD.
When -Parallel ESI is de-asserted (high), the backplane must present SEL_ID information on SEL_n/
P_ESI_n. See SEL_ID Function.
When -Parallel ESI is asserted (low), the backplane must present Enclosure Service Information (if
supported) on SEL_n/P_ESI_n. See SEL_ID Function on page 16.
Note: The maximum response time to a change in state of -Parallel ESI is 1μS.
IOPS
Zeus
3.5-Inch Fibre Channel Solid State Drive Product Manual Rev. 1.0 29
SEL_ID FUNCTION
The SEL_n (TTL compatible) inputs (defined when -Parallel ESI is de-asserted) provide a binary
value of a loop identifier to the drive. These seven (7) signals define 128 possible values and are
directly translated into an 8 bit hard Arbitrated Loop Physical Address (AL_PA). Only AL_PAs with
neutral disparity are valid values. The drive will attempt to acquire this hard AL_PA during the LIHA
phase of the Loop Initialization Process (LIP). Table 7 lists the SEL_ID/AL_PA translation in
hexadecimal format.
NOTE: An AL PA value of 0x00 is not valid for an NL_Port. A SEL_ID
of 0x7F will force the SSD to obtain a soft address.

SFF-8045 ENCLOSURE SERVICE INTERFACE
The SFF-8045 Enclosure Service Interface defines 7 bits of enclosure status. This status is read by
the drive, and presented to the Initiator, upon receipt of appropriate Receive Diagnostic command.
The definitions of the status bits are vendor specific. The drive will not interpret the status. The drive
assumes -EFW is status and treats it as if does the other P_ESI_n signals.
-ENBL_BYP CH1 AND -ENBL_BYP_CH2
These two signals are TTL outputs from the drive and provide 4mA of sink capability. The signals are
intended to control the state of the loop port bypass circuit on the backplane. The drive powers up
with these signals turned off. It is assumed that the backplane will provide a 1K ohm pull-down
resistor that will ensure the drive is bypassed on the loop when it is not present, or when it is powering
up. The drive will attempt to enable itself on both loops after a successful power up.
START_n MATED
These signals are used to control the motor spin on rotating media drives. Because the Zeus

-DRIVE PRESENT

DEV_CTRL_CODE_X
The DEV_CTRL_CODE_2 through DEV_CTRL_CODE_0 signals provide a binary code to the drive
to control functions such as FC link rate, Power Failure Warning (PFW) and Hard Reset. The control
function is either identified by a code or a sequence of codes on the DEV_CTRL_CODE signals.
Table 9 lists the functions and the associated codes that use a decode value on the
DEV_CTRL_CODE signals.
The Hard Reset function uses a sequence of values on the DEV_CTRL_CODE signals. The
sequence is 5, 1, 3, 2, 3, 1 and 5. A drive detecting a valid Hard Reset sequence shall perform the
equivalent of a power-on reset.
4.7K ohm pull-up resistors to 3.3V are provided on the drive for both DEV_CTRL_CODE_2,
DEV_CTRL_CODE_1 and DEV_CTRL_CODE_0 to ensure that each signal is maintained in its high
state unless a low is provided from the backplane.

The Zeus
2 interface connector, a Host FPGA, which contains a processor, NAND FPGA, NAND flash memory,
and DRAM.
Read/write data transfer requests are initiated by the host via the SCSI bus interface. Once received,
the Host FPGA controller, under the direction of the microcontroller, processes the request.
The FPGA NAND flash controller interfaces with the NAND flash chips and sequences the data flow
between the DRAM and flash.
Read and Write commands have dedicated hardware functions that do not require firmware support,
thereby increasing performance. Some commands may require the host controller to use external
circuitry that do not involve the flash memory controller.

Fibre Channel SSD is comprised of the following primary functional blocks: the SCA-
It is the microcontroller that will initiate and monitor all
activity within the controller, including the execution of the

The controller will decode an incoming host command, and
will configure the appropriate interrupts and status for the
local microprocessor to handle various SCSI commands. For
read and write transfer commands, there are hardware
functions that minimize firmware overhead to enhance
performance.
When a Read or Write operation is requested, the integrated DMA controllers transfer the Fibre
Channel frames to and from the SSD DRAM.

FIBRE CHANNEL STANDARD
The Fibre Channel standard has coined various terms that are important to know when using the

understanding of the Fibre Channel interface.
FIBRE CHANNEL ARBITRATED LOOP
SSD. This section will present the basic terms in context to help provide an intuitive
The “Fibre” or “link” refers to the copper or optical cable that connects two Fibre Channel devices via
their ports. A device, known as a “node”, can have more than one port. For example, the Zeus
SSD is a node with two ports that is linked with a copper cable, or fibre.
Nodes are connected in a “topology”. The SSD may be connected to an “Arbitrated Loop” (AL), where
the nodes of the loop are connected in a circle. See Figure 4.
IOPS
Zeus
Figure 4. Arbitrated Loop Topology Connection
IOPS
3.5-Inch Fibre Channel Solid State Drive Product Manual Rev. 1.0 53
An Arbitrated Loop has certain rules:
1 Each port on the loop has an Arbitrated Loop Physical Address (AL-PA) that is set on the
“backplane” or the board to where the device is connected. Once set, the port attached to
the backplane inherits the AL-PA.
2 The AL-PA must have “neutral disparity”, i.e., the number of binary 0s and 1s in the AL-PA
are equal when 10-bit encoded. Out of the 127 addresses, one is reserved on the loop for
the fabric switch, leaving 126 possible AL-PAs.
3 There may be more than 126 ports physically attached to the on a loop, but only 126 will
be functional, with the remaining unable to obtain valid addresses.
4 If the AL-PA of a device is not unique on the loop, the device will not participate on the loop.
The user must choose another “hard address”, i.e., an AL-PA. If a unique hard address
cannot be set, the user can set the backplane to an AL-PA so that the loop will assign a
“soft address” to the device.
5 The lower the AL-PA, the higher priority the device has on the loop while keeping “fairness”.
Fairness means that every device on the loop has a chance to own the loop once before
another device owns it twice.

An Arbitrated Loop has the following states:
Monitoring Each port acts as a repeater while listening for further instructions.
Arbitration The port requests to own the loop.
Open The port wins arbitration and connects to another device.
Closed
The port relinquishes control of the loop and the loop is in the process of returning
to a monitoring state.
A node can be “hot plugged” where it is inserted or removed from the loop. When hot plugged, the
loop loses “sync” and must “reinitialize”. The loop will be able to recover any lost communications
during the hot plugging. Typically, a backplane may have a “bypass” circuit. See Figure 6. When
enabled, the bypass circuit will remove the device from the loop while keeping the loop connected.
The loop will remain operational while the device is connected, performs its POSTs, and becomes
ready.

INSTALLATION
SYSTEM REQUIREMENTS
There is a risk of electrocution! Use extreme caution when
handling the solid state drive and while connecting it to a
power source. Observe all applicable electrical safety rules
while installing the solid state drive. Make sure to read and
thoroughly understand this section before attempting to
install the drive.
SCSI CONNECTIONS
The Zeus
supports SCSI-3 or greater devices (the SSDs are intended to be compliant to future SCSI-4
standards). If the system does not have a Fibre Channel AL-Port, the user will need to supply and
install an adapter before proceeding with the installation. If the system fails to recognize the drive,
make sure the most recent drivers for the host adapter are installed. If the drive is connected to the
motherboard, the drivers are provided by the motherboard manufacturer. Changes to the operating
system are not required.
Make sure the following is on hand before installing the SSD:
IOPS
3.5-inch Fibre Channel SSD can be installed in an operating system environment that
• Phillips screwdriver
• Six M3 machine screws
• A cable suitable to connect the backplane or tailgate card to the HBA
• An available tailgate card or backplane connection.
• Available 12V power source
SINGLE CHANNEL OPERATION
The Zeus
This allows the drive to be used on systems that have multi-pathing software, also known as
“Dynamic Multi-Pathing” or DMP. The DMP software allows for two completely separate paths from
the one host machine to access the same drive; the two separate paths are recognized as being
logically connected together. This allows for some redundancy to be incorporated into the system.
Systems that support DMP typically send commands to the drive down both channels, using the
channel that is the least busy. If one channel fails for any reason then all commands are automatically
switched to use the remaining active channel.
62 Zeus
IOPS
SSD is dual-ported and can be accessed simultaneously down both ports or channels.
IOPS
3.5-Inch Fibre Channel Solid State Drive Product Manual Rev. 1.0
For host systems that are not DMP capable, having two paths from the same host machine to the
same drive can cause problems. For example, if the two channels are connected to the same host
machine when running an operating system that does not support DMP, two separate disks will be
reported by the operating system even though both reported disks are the same physical storage.
This can cause corruption to occur if the drive is subsequently accessed down both channels. See
Single Channel Mode for Early Revision Drives on page 66.
DRIVE CONFIGURATION
To accommodate both DMP and non-DMP capable systems, the SSD can be configured so that it
only operates (and is only visible) down one of the two channels. This feature is most likely to be used
on systems that do not support DMP but where the drives in the same JBOD chassis are to be
mirrored. Enabling just the A channel for the main drive and the B channel on the mirror drive will
cause both drives to be visible via separate host channels, thereby preventing any single point of
failure.
The feature is enabled by inserting a 2mm option jumper onto the two pins marked as JP1 on the
underside of the drive. Please note that jumper JP1 is located on the 10-way right-angled connector
that also serves as a test connector during manufacture. The drive will require power cycling after
JP1 is installed or removed. When this feature is enabled, the LSB of the SELECT_ID determines the
port that the drive will use. If the SELECT_ID is even, then port A is used. If the SELECT_ID is odd,
then port B is used.
WARNING: Only insert a jumper across the pins clearly labeled as JP1
on the PCB silk-screen. If JP1 is not marked, then please read the
following for information regarding early revision drives.
FAULT SIGNALS
Under certain conditions, the SSD will drive the Fault LED Out (fault signal) on the SCA-2 interface.
In most system configurations, this will normally be connected to an LED on the chassis that is visible
to the user.

POWER-ON FAULT CONDITIONS
The fault codes listed in Table 37 indicate that a fault has been detected during the power-on

the unit.
Power-on fault codes are indicated as a series of flashes. The fault light will illuminate for 0.25
seconds (250mS), then turn off for 0.25 seconds (250mS), followed by a 2 second off interval. The
number of flashes between each 2 second off period is used to indicate the different fault conditions.

Operational fault codes are indicated as a series of flashes. The fault light will illuminate for 1 second,
then off for 1 second, followed by a 10 second off delay. The number of 1 second flashes between
each 10 second delay period are used to indicate the different fault conditions: 5, 7 or 9 flashes.

event of a power failure. The backup power allows the
firmware to ensure that any active writes are completed. It
also allows information to be saved so that the drive
becomes ready promptly (< 30 seconds) when po wer is
restored. If this fault code is active and power is
unexpectedly lost, the drive may require several minutes to
come ready when the power is restored. If this occurs, only
the data blocks that were most recently written by the host
will be lost. If those same data blocks are read when power

SINGLE CHANNEL MODE FOR EARLY REVISION DRIVES
On early revisions of the drive, JP1 did not exist. These drives are identified by having a serial number
of “50” or less and only have an 8-way right-angled manufacturing connector. For this revision of
drive, the feature is enabled by setting bit 6 of the LOOP_ID to “1”. The LOOP_ID is set using the
SELECT_ID pins on the SCA-2 connector within the chassis to which the SSD is connected. See the
SEL_ID Function on page 30.
The SELECT_ID bits are normally configured by jumpers or a switch that allows the ID of the drive
to be set using the backplane of the SCA-2 connector. Table 39 lists the various configurations of the

DRIVE INSTALLATION
Electro Static Discharge or ESD can seriously damage the
electronic components of the host system and solid state
drive. It is very important to discharge any static electricity
before you begin the installation procedure. You can touch an
unpainted, grounded metallic surface to discharge any static
charges that may be present on your body or clothing. As an
alternative, you can also use an ESD protective wrist strap.
You can minimize the possibility of damage due to ESD by
avoiding physical contact with the electronic components.
To install the SDD in a server or host system:
1 Power down the computer/host system.
2 Remove the access cover.
3 Position the SSD in an available drive bay or choose a suitable mounting location.
4 Connect the SSD to the backplane or tailgate card. The connector on the drive is keyed to
ensure that the signal and power connections to the drive are correctly oriented.
5 Secure the SSD within the drive bay or to the mounting surface using M3 machine screws.
Apply sufficient torque to ensure that the drive is secure.
Note: Be aware of the depth of the drive’s mounting holes. The maximum penetration
depth of the drive’s mounting holes is indicated in Figure 15 on page 60. The user may
mount the drive using the side or underside mounting holes. Four (4) M3 screws will be
required to mount the drive from the bottom; six (6) M3 screws to mount the drive using the
side holes. It is recommended that the user secure the drive with at least four screws. To

SYSTEM POST, BOOT AND RESUME TIMES
The time required for the drive to become ready varies according to the capacity. The average time
is 30 seconds. The total boot time will vary depending on the state of the capacitor-based power
backup module. Under normal operation, the module will remain in a state where it holds enough of
a charge to that the charging causes no delay to the boot-up. When the drive is new or remains
without power for many hours, the capacitors on the power backup module will be discharged. If the
capacitors are fully discharged the drive will take longer to start. For example: 18GB, fully discharged
35 seconds, charged 11 seconds; 146GB fully discharged 45 seconds, charged 23 seconds.

SSD MANAGEMENT UTILITY
The firmware and hardware on a Zeus
IOPS
SSD can be upgraded in the field. The drive management
utility, “Giddy”, uses signed Java applet technology and the Java native interface to maintain the
SSD. Table 40 lists the supported operating systems, Java Runtime Environments (JREs) and
compatible web browsers. The documentation for the Management utility is found at http://
www.gnutek.co.uk/giddy.pdf.
Notes:
1 The end user is required to have administrator rights to execute the management utility.
2 The utility is capable of updating the firmware or the programmable gate arrays (“hardware
upgrade”).
3 The SSD will log internal events during normal operation. These “messages” are transparent to
the host. In the event of an error, the utility is capable of extracting these messages that can be
sent to the manufacturer for diagnostic purposes.
4 The user can choose to erase or sanitize the drive.
5 The utility will not permit updating the device with firmware intended for another model or
version of the device.
