Figure 2-6 shows a fully configured three-frame DS8884 configuration. The leftmost frame is the base frame that contains the processor complexes, I/O enclosures, standard drive enclosures, and HPFEs Gen2. The second frame is the first expansion frame that contains I/O enclosures, HPFEs, and standard drive enclosures. The third frame is also an expansion frame that contains only standard drive enclosures. 

Each frame contains two standard single-phase DC-UPSs that supply redundant power for all installed components. All DC-UPSs in a system contain one BSM set, whether the ePLD feature is installed or not. 

Note:  The DS8884 configuration supports only single-phase input power.

## 2.2.7 DS8880 base frames 

As mentioned in 2.1.1, “Storage system” on page 26, the DS 8880 storage system is available indifferent base frame models. Each base frame model number is determined by the configuration and the hardware version. The specific combinations are shown in Table 2-1 on page 26. 

Note:  All DS8880 frames are 19 inches wide with a 40U capacity. The DS8886 frames and DS8888F optionally can be extended from 40U to 46U to allow greater storage capacity in a smaller footprint. 

The DS8880 base frames accommodate the following components: 

GLYPH<SM590000> High-Performance Flash Enclosure Gen2, in the following configurations: 

– Up to four HPFE Gen2 enclosure pairs in the DS8888F configuration base frame. 

– Up to four HPFE Gen2 enclosure pairs in the DS8886F configuration base frame.
