Hardware component descriptions

On the rear of the storage processor, viewing from left to right, are:

• Two RJ-45 LAN connectors (labeled with a network management symbol and a wrench symbol) management ports
• SP status LEDs
• One mini-HDMI port and one USB 3.0 port
• Reset button (NMI)
• Two 10-GbE ports
• Two 12-Gb/s mini-SAS HD ports
• Two integrated Converged Network Adapter (CNA) ports

The following illustration shows the location of the SP components:

Location	Description	Location	Description
	Management LAN (RJ-45) port		SP unsafe to remove LED (black with white hand)
	Grounding screw (required for DC-powered systems)		SP fault LED
	Torque knob for SP removal		SP power LED
	Two converged network adapter (CNA) ports (labeled 4 and 5)		Non-maskable interrupt (NMI) push button (password reset button) a
	Two 12 Gb/s mini-SAS HD ports (labeled 0 and 1)		SP memory or boot fault LED
	Two 10 GbE ports (labeled 2 and 3)		Mini-HDMI port (not used)
	USB 3.0 port		Service LAN (RJ-45) port

a. NMI = non-maskable interrupt, push button used for password reset and forcing a system dump. Hold for 2 seconds to reset the password. Hold for 10 seconds or more forces a reboot.

The following table describes the SP status LEDs.

Table 7. Storage processor LED details

LED	Location	Color	State	Description
SP power LED		Green	On	The SP is on main power.
			Blinking (1Hz)	The SP is initializing a serial over LAN (SOL) session (standby mode).
		—	Off	The SP is off.
Unsafe to Remove LED		White	On	DO NOT remove the SP. Note:  Improper removal of the SP when this LED is lit could cause data loss during critical situations.
		—	Off	Safe to remove the SP without the risk of data loss when the SP has been properly prepared.
SP fault LED		Amber	Blinking once every four seconds (.25 Hz)	BIOS is running.
			Blinking once every second (1 Hz)	POST is running.
			Blinking four times every second (4 Hz)	POST completed and OS boot has started.
			On	An SP fault detected.
		Blue	Blinking once every four seconds (.25 Hz)	Operating system is booting.
			Blinking once every second (1 Hz)	Operating system driver is starting.
			Blinking four times every second (4 Hz)	Operating system caching driver is starting.
			On	SP is in degraded mode. System not initialized. A management IP address is assigned. Note:  Once license accepted, the SP fault LED turns off.
		—	Off	All operating system software has booted and SP is ready for I/O.
		Amber and blue	Alternating at one second intervals	SP is in Service mode.
			Amber then immediately blue every three seconds	System not initialized and no management IP address assigned.
SP memory or boot fault LED		Amber	On	The SP cannot boot due to a memory or boot fault.
		—	Off	Normal Operation.

Each SP contains two integrated CNA ports (labeled 4 and 5). These ports are PCI Express 3.0 x4 adapters that provide interfaces that can be configured as Ethernet, or Fibre Channel, but once set to a protocol, cannot be changed. If CNA ports are set to Ethernet, then you can use either 1Gb/s, 10Gb/s SFPs or Twin-AX for File (IP) or iSCSI Block access. If the ports are set to Fibre Channel, then you can use SFPs supporting 4, 8, 16 Gb/s FC multi-mode, or single-mode SFPs supporting 16Gb/s only.

NOTICE  Once you set the network protocol on the CNA ports you cannot switch to a different network protocol. Additionally, the four CNA ports cannot be configured independently; they must all be configured with the same network protocol. For example, if you configure the CNA ports for 10Gb/s Ethernet you cannot then later switch these ports to Fibre Channel.

Many I/O module types are supported by the storage processor.

NOTICE  When adding new I/O modules, always install I/O modules in pairs—one module in SP A and one module in SP B. Both SPs must have the same type of I/O modules in the same slots.

Refer to Platform Overview for a details on the supported types and the system limits of storage processor I/O modules.

• Four-port 12-Gb/s SAS I/O module -- where supported, provides four mini-HD SAS ports (x16 lane) of 12Gb SAS expansion for connecting additional DAEs. This I/O module also supports controller based encryption. Labeled 12Gb SAS v1.
• Four-port 16-Gb/s Fibre Channel I/O module -- provides Fibre Channel connectivity as listed below. Labeled 16Gb Fibre v3.
  • Four ports auto-negotiating to 4/8/16Gbps. Uses optical SFP+ and OM2/OM3 cabling to connect directly to a host HBA or FC switch.
  • One FC port negotiating to 16Gbps, which can be configured for synchronous replication between two Unity systems, either directly connected or connected through a switch. Uses optical SFP+ and SM or MM cabling to provide synchronous replication. The three remaining ports auto-negotiate to 4/8/16 Gbps, and use optical SFP+ and OM2/OM3 cabling to connect directly to a HBA or FC switch.
• Four-port 10-Gb/s optical I/O module -- provides four SFP+ optical or Active/Passive TwinAx 10GbE IP/iSCSI ports for connections to an Ethernet switch. Supports both IP(file) and iSCSI (Block) on the same I/O module. Ports can be configured as both IP and iSCSI simultaneously. Labeled 10 GbE v5.
• Four-port 10GBASE-T I/O module -- provides four copper 10GBASE-T RJ45 Ethernet ports for copper connections to an Ethernet switch. Supports both IP (file) and iSCSI (Block) on the same IO module. Ports can be configured as both IP and iSCSI simultaneously. Labeled 10GbE BaseT v2.
• Four-port 1GBASE-T I/O module -- provides four 1000BASE-T RJ-45 copper ports for Cat 5/6-cabling connections to an Ethernet switch. Supports both IP (file) and iSCSI (Block) on the same I/O module. Ports can be configured as both IP and iSCSI simultaneously. Labeled 1 GbE BaseT v3.
• Two-port 10Gb/s optical I/O module -- provides two SFP+ optical or Active/Passive TwinAx 10GbE ports for connections to an Ethernet switch. Supports both IP (file) and full iSCSI Offload engine (Block) on the same IO module. Ports can be configured as both IP and iSCSI simultaneously. Labeled 10 GbE V6.
