2. Page 2 Introduction to File Engines Interface module Each node has six I/O module slots. Each node has a GE card for heartbeat signaling. Each node has an 8 Gbit/s Fibre Channel card for disk array connection. Each node has a maximum of four GE or 10GE cards for interfacing with NAS hosts. Being based on the Pangea V001R001 hardware platform (namely the controller enclosure of an S5500T/S5600T/S6800T), the file engine of a T series unified storage system is also 4 U high. Each controller in this independent engine serves as a file engine node, and each engine serves as a two-node file engine. Controller-file engine Each controller serves as a node.

Heartbeat network of a two-node file engine Note: The GE I/O Module comes with File engine can only be used for heartbeat. The host connectivity requires extra I/O Module

4. Page 4 Introduction to S2600T Storage Controllers Power module Adopts 1+1 redundancy. Offers a power conversion efficiency up to 92%, which is higher than the 88% of conversion efficiency for golden power supplies. Fan/BBU module Adopts 3+1 redundancy for fan modules, ensuring system continuity when a single fan module becomes faulty. Supports delicate and intelligent fan speed control. Embeds BBUs against the data loss caused by expected power failures. Control unit in the disk and controller integration configuration Provides management network ports and serial ports. Carries two onboard 4x6 Gbit/s SAS ports. Supports one expansion I/O module. Carries four onboard 8 Gbit/s Fibre Channel ports. 3.5-inch controller enclosure Supports 12x3.5-inch disks. Supports mainstream SAS and NL-SAS disks as well as SSDs. Houses four 2+2 redundant coffer disks in the first four slots. Supports the independent power-on or power-off of each disk.

12. Page 12 1. Choose an appropriate RAID level. ▬ Chooses a suitable RAID level from the supported RAID 0, 1, 5, 6, 10, and 50 based on the actual application scenario. ▬ As recommended, uses RAID 5 or 1 SAS or Fibre Channel disks ▬ You need to use RAID 6 for a RAID group that consists of NL-SAS disks or SATA disks. (The ISM uses RAID 6 by default). 2. Configure a moderate number of disks for each RAID group. ▬ The optimal number of disks configured for one RAID 5 or RAID 6 group is 8 to 11. ▬ Configures a maximum of 16 disks for each RAID 10 group. ▬ Weighs the disk utilization ratio, disk failure rate, reconstruction duration, and disk performance when you choose a RAID level. 3. Deploy hot spare disks. ▬ Deploys hot spare disks whenever possible. ▬ Avoids using coffer disks as hot spare disks. ▬ As recommended, configures at least one hot spare disk for each enclosure and at least two for the sole controller enclosure. 4. Intermix different types of disks in practice. ▬ Avoids intermixing high-speed disks with low-speed ones within the same enclosure. ▬ Configures dedicated hot spare disks for different types of disks. 5. Calculates the available capacity of disks according to the RAID level (redacted). 6. Configures an ideal of no more than 72 and a maximum of less than 120 disks for each pair of back-end ports.
