7700 Hardware Overview

This page contains information and instructions to help prepare you for servicing replaceable components in the Sun ZFS Storage 7700 appliance. For instructions on how to replace appliance components or for more information about the system controller, refer to the following pages:

Cabinet Specifications

The Sun ZFS Storage 7700 appliance cabinet houses all of the components that support a clustered storage system. The cabinet includes 12 cages that host 30 hard disk drives (HDDs), 2 leaf controller cards (LCCs), and 2 optional Logzilla solid state drives (SSDs). To control these resources, the appliance includes 2 system controllers and 2 rack controller cards (RCCs) on internal and external SAS and Ethernet networks. To power and cool the components, the cabinet includes 6 power supplies (PSUs) and 3 fan trays.

The lower cabinet is populated with 2 3U Sun ZFS 7720 storage controllers containing 4-socket CPU motherboards with large memory capacities, 4 optional read-optimized Readzilla SSDs and 10 PCIe slots with installed adapters that are clustered by default in a high availability configuration.

External Components

This section includes descriptions about the main components included in the 7700 main cabinet.

External Cables

The 7700 appliance is shipped with installed external cables located behind the cabinet doors. SAS cables connect the RCCs to the storage controllers, and Ethernet cables connect the internal Ethernet bus between the system controllers.

The external cables consist of power and data cables. The power cables (1) connect the power supplies and system controllers in the main cabinet to the power circuits (2 and 3) in the facility that connect to the power sources (4 and 5). Image

The following illustration shows the data cables that create the default cluster configuration between the system controllers and the RCCs. Image

Fan Trays

Each 7700 cabinet comes with three fan trays that each host three fan modules. Individual fan modules cannot be replaced; the entire fan tray must be replaced.

Caution: Operating a cabinet for an extended period of time with a fan tray removed reduces the effectiveness of the cooling system, and may initiate an emergency thermal shutdown. Unpack the replacement fan tray in advance, and insert it into the cabinet as soon as the faulted fan tray is removed. Cooling for the 7720 controllers is independent from that of the 7700 cabinet, but the same guidelines apply when replacing fans in a controller. Image

Drive Cages

The 7700 appliance cabinet hosts 12 drive cages (6 on each side). Each cage hosts 30 HDDs, 2 SSDs and 2 LCCs. Drives can be hot-swapped. Image

Leaf Controller Cards

The leaf controller cards (LCCs) are the final SAS fan out to the HDDs that are the leaves in the SAS topology. Each drive cage has 2 LCCs that are load-balanced. In the event of a fault, one LCC provides connectivity to the HDDs. The LCCs can be hot-swapped without shutting down the appliance. If both an LCC and RCC (see below) are being replaced at the same time, replace the RCC first.

Image
Power Supplies

Each 7700 cabinet comes with 6 power supplies near the bottom of the cabinet. The power supplies can be hot-swapped while the system is running. The system controllers also have power supplies. See the 7x20 Overview for more information. Image

Root Controller Cards

The 7700 appliance contains two RCCs that are located between the storage controllers and the drive cages. In the event of an RCC failure, one RCC can provide connectivity to both system controllers and the drive cages. The RCCs are the primary interface to the storage controllers and the root of the SAS topology. The RCCs are hot-swappable, but they must be replaced by a Sun service technician. If both an RCC and one or more LCCs are being replaced at the same time, replace the RCC first. Image

Solid State Drives

All of the drive cages and both system controllers use SSDs as part of the hybrid storage pool, seamlessly adding flash into the storage hierarchy for performance. Slots 30 and 31, if populated, are dedicated to write-optimised SSDs. Zero to 2 SSDs may optionally be present in each cage. Populate all of the drive cages containing LCCs with one SSD in slot 30 before adding a second SSD to any of the cages.

The minimum SSD configuration is four SSDs per base cabinet. Refer to 7420/7720 CPU and Memory components for other storage controller component guidelines.

Internal Components

The following sections contain descriptions of the internal components in the Sun ZFS Storage 7700 appliance. Note: All internal components must be serviced by a Sun Service technician.

Cabling

The internal cables deliver power to the components and plumb the necessary SAS and Ethernet connections between the backplanes, storage controllers and RCCs. All cabling connections are shown in the cabling label on the inside of the cabinet. Failed internal cables must be replaced by a Sun Service technician.

Interface Boards

The 7700 cabinet includes several internal interface boards. There are no CRUs inside the 7700 cabinet, and access to the internal interface boards is limited to Oracle's Sun Service technicians.
