Dot Hill Systems II 200 FC service manual Sfp

Table 1-2shows the configuration options for SANnet II 200 FC, SATA, and SATA SE arrays.

Table 1-2SANnet II 200 FC, SATA, and SATA SE Array Configuration Options

Internal RAID controllers	1 or 2
2-Gbit/sec Fibre Channel disks	Up to 12 per array or per expansion unit, with a
(SANnet II 200 FC array)1	minimum of 4 plus 1 spare
1.5-Gbit/sec serial ATA disks
(SANnet II 200 SATA array)
FC expansion units2	Up to 8 for a SANnet II 200 FC array. Up to 5 for a
	SANnet II 200 SATA array
FC JBOD arrays3 (SANnet II	1
200 FC array only)
Connection options	•	Serial port
	•	Ethernet
	•	Fibre Channel Small Form-Factor Pluggable
		(SFP)
Supported RAID levels	0, 1, 3, 5, 1+0, 3+0, and 5+0
Redundant field-replaceable	•	Power supply and fan modules
units (FRUs)	•	I/O controller modules and I/O expansion
		modules
	•	I/O expansion modules
	•	Battery board module
	•	Disk drive modules
Configuration management	•	In-band Fibre Channel ports
and enclosure event reporting	•	Out-of-band 10/100BASE-T Ethernet port
options4	•	RS-232 connectivity
	•	Enclosure monitoring by SCSI Enclosure Services
		(SES)

1.1-GHz drives are not supported.

2.A disk array with no controller. Each expansion unit has two Fibre Channel loops that can provide redundant data paths back to the RAID array.

3.A disk array with no controller that is connected directly to a host computer, with no RAID array in the loop. Only SANnet II 200 FC arrays support the JBOD configuration.

4.The host-based SANscape software provides a graphical user interface (GUI) and additional event-reporting capabilities.

A label on the bottom lip of an array chassis, underneath the front bezel, indicates whether the array is a JBOD array or a RAID array. For instance, “SANnet II 200 AC JBOD” refers to an alternating-current version of a SANnet II 200 JBOD array, “SANnet II 200 DC JBOD” refers to a direct-current version of a JBOD array, and “SANnet II 200 AC RAID” refers to an alternating-current version of a RAID array. Similarly, using a OBP command such as probe-scsi-allprovides similar information, using an “A” designator for RAID arrays and a “D” designator for disks
