Oracle ZFS Storage ZS7-2 Storage Drive

This section shows the location and explains the functions of the storage drive status indicators.

1 Ready to Remove (blue)

2 Service Action Required (amber)

3 OK/Activity (green)

Oracle ZFS Storage ZS7-2 Fan Module

The four fan modules are located towards the front of the Oracle ZFS Storage ZS7-2 controller between the CPUs and the drive trays. The fan modules are designated from left to right. As pictured in the following illustration, the four fan modules are designated as: FMO, FM1, FM2, and FM3.

LED Color and State Meaning
Amber – The fan module is faulty. The front Top Fan LED and the front and back panel Fault-Service Required LEDs are also lit if the system detects a fan module fault.
Not Illuminated – The fan module is operational (OK).

Oracle ZFS Storage ZS7-2 Power Supply

The two power supplies are located on the right side of the controller (from the front of the controller) and are designated from top to bottom. The power supplies are accessible from the back of the controller. As indicated in the following drawing, the top designation is PS 1 and the bottom designation is PS 0.

1 Power supply 0

2 Power supply 1

The two power supplies ensure redundancy by allowing the controller to operate when one of the power supplies fails. However, when the controller is operating on one power supply, redundancy no longer exists, and the risk for an unexpected shut down and a loss of data is high. When a power supply or any component that is part of a redundant configuration fails, replace it immediately.

1 Power supply (PS) 1	3 PS 0
2 PS 1 status indicators: Fault-Service Required LED: amber; AC power input and DC power output OK LED: green	4 PS 0 status indicators: Fault-Service Required LED: amber; AC power input and DC power output OK LED: green

Oracle ZFS Storage ZS7-2 DIMM

The physical layout of the DIMMs and processor(s) is shown in the following figure. When viewing the controller from the front, processor 0 (P0) is on the left.

Each processor, P0 and P1, has 12 DIMM slots organized into 6 memory channels. Each memory channel contains two DIMM slots: a black DIMM slot (channel slot 0) and a white DIMM slot (channel slot 1).

As shown in the following figure, DIMM slots are labeled D0 through D5 to the left of each processor, and D6 through D11 to the right of each processor. For each processor, the black slots are: D0, D2, D4, D7, D9, and D11. Similarly, for each processor, the white slots are: D1, D3, D5, D6, D8, and D10.

The following table describes the supported memory configurations for Oracle ZFS Storage ZS7-2. The mid-range model supports 8 or 16 DIMMs, and the high-end model supports 24 DIMMs. All DIMMs are 64 GB. The DIMM locations in the table apply to both P0 and P1 processors; for example, P0/D2,P0/D4,P0/D7,P0/D9 and P1/D2,P1/D4,P1/D7,P1/D9.

Configuration	Total DIMMs Installed	DIMM Slots Populated	DRAM Capacity	Description
Oracle Storage ZS7-2 mid-range model, low-memory configuration	8	D2, D4, D7, D9	512 GB	Black sockets are populated
Oracle Storage ZS7-2 mid-range model, high-memory configuration	16	D2, D4, D7, D9 D3, D5, D6, D8	1024 GB	Black sockets are populated White sockets are populated
Oracle Storage ZS7-2 high-end model	24	D0, D2, D4, D7, D9, D11 D1, D3, D5, D6, D8, D10	1536 GB	Black sockets are populated White sockets are populated

Oracle ZFS Storage ZS7-2 Storage Drives

Only two of the storage drive slots are used for system boot purposes, which include redundant mirrored drives. These are used and designated consecutively from left, bottom (System Disk 0) to right (System Disk 1). All other storage drive slots include filler panels as is indicated in the following drawing. Drive slots are numbered from left to right, and from bottom to top.

1 System Disk 0	5 Filler panel	9 Filler panel
2 System Disk 1	6 Filler panel	10 Filler panel
3 Filler panel	7 Filler panel	11 Filler panel
4 Filler panel	8 Filler panel	12 Filler panel
