Exos 7E8 drives are random access storage devices designed to support the Serial Attached SCSI Protocol as described in the ANSI specifications, this document, and the SAS Interface Manual (part number 100293071) which describes the general interface characteristics of this drive. Exos 7E8 drives are classified as intelligent peripherals and provide level 2 conformance (highest level) with the ANSI SCSI-1 standard.
Standard features Exos 7E8 drives have the following standard features: • 128 - deep task set (queue) • 256MB data buffer (see Section 4.4). • 3.0 / 6.0/12.0 Gb Serial Attached SCSI (SAS) interface • Drive Self Test (DST) • Embedded servo design •...

Performance characteristics This section provides detailed information concerning performance-related characteristics and features of Exos 7E8 drives. Internal drive characteristics Drive capacity 6TB models (formatted, rounded off value) Read/write data heads Bytes/track 2,179,072 Bytes (average, rounded off values) Bytes/surface 1,300,000 MB (unformatted, rounded off values)
Sending a size specification using the Mode Select command (bytes 14 and 15) does not set up a new segment size. If the STRICT bit in Mode page 00h (byte 2, bit 1) is set to one, the drive responds as it does for any attempt to change an unchangeable parameter. Seagate Exos 7E8 SAS Product Manual, Rev. A...
When prefetch (read look-ahead) is enabled (enabled by DRA = 0), the drive enables prefetch of contiguous blocks from the disk when it senses that a prefetch hit will likely occur. The drive disables prefetch when it decides that a prefetch hit is not likely to occur. Seagate Exos 7E8 SAS Product Manual, Rev. A...
An interface error is defined as a failure of the receiver on a port to recover the data as transmitted by the device port connected to the receiver. The error may be detected as a running disparity error, illegal code, loss of word sync, or CRC error. Seagate Exos 7E8 SAS Product Manual, Rev. A...
Reliability and service Users can enhance the reliability of Exos 7E8 disk drives by ensuring that the drive receives adequate cooling. Section 6.0 provides temperature measurements and other information that may be used to enhance the service life of the drive. Section 8.2 provides recommended air-flow information.

(not to exceed zero) whenever the error rate is acceptable. If the counter continually increments such that it reaches the predictive threshold, a predictive failure is signaled. This counter is referred to as the Failure History Counter. There is a separate Failure History Counter for each attribute. Seagate Exos 7E8 SAS Product Manual, Rev. A...
5.2.4 Thermal monitor Exos 7E8 drives implement a temperature warning system which: Signals the host if the temperature exceeds a value which would threaten the drive. Saves a S.M.A.R.T. data frame on the drive which exceeds the threatening temperature value.

Installation Exos 7E8 disk drive installation is a plug-and-play process. There are no jumpers, switches, or terminators on the drive. SAS drives are designed to be used in a host system that provides a SAS-compatible backplane with bays designed to accommodate the drive. In such systems, the host system typically provides a carrier or tray into which users need to mount the drive.

Invalid logical unit Dual port support Exos 7E8 SAS drives have two independent ports. These ports may be connected in the same or different SCSI domains. Each drive port has a unique SAS address. The two ports have the capability of independent port clocking (e.g. both ports can run at 12Gb/s or the first port can run at 6Gb/s while the second port runs at 3Gb/s.) The supported link rates are 3.0, 6.0, or 12.0 Gb/s.
