requires higher levels of cooling, they automatically speed up fans to increase airflow across

1.5 Disk and media features
Three backplane options are available for the Power S822 and provide a great deal of
flexibility and capability. One of the three options must be configured:
1. Storage Backplane with 12 SFF-3 bays and one DVD bay (#EJ0T)
2. Storage Backplane with 12 SFF-3 bays and one DVD bay (#EJ0T) and feature EJ0V
provides split backplane functionality
3. Storage Backplane with 8 SFF-3 bays, 1.8-inch SSD cage bays, one DVD bay, dual
integrated SAS controllers with write cache and Easy Tier functionality (#EJ0U)
Each of the three backplane options provides SFF-3 SAS bays in the system unit. These
2.5-inch or small form factor (SFF) SAS bays can contain SAS drives (HDD or SSD) mounted
on a Gen3 tray or carrier. Thus the drives are designated SFF-3. SFF-1 or SFF-2 drives do
not fit in an SFF-3 bay. All SFF-3 bays support concurrent maintenance or
hot plug capability.
In addition to supporting HDDs and SSDs in the SFF-3 SAS bays of the Power S822, the
storage backplane feature EJ0U supports a mandatory 6-bay, 1.8-inch SSD Cage (#EJTL).
All six bays are accessed by both of the integrated SAS controllers. The bays support
concurrent maintenance (hot plug). The SSD 1.8-inch drive such as the 387 GB capacity
feature ES16 (AIX, Linux) is supported.
The high performance SAS controllers provide RAID-0, RAID-5, RAID-6 and RAID-10
support. The dual SAS controllers can automatically move hot data to attached SSD and cold
data to attached HDD for AIX, and Linux environments using the Easy Tier functionality.
Table 1-5 shows the available disk drive feature codes that can be installed in the
Power S822.
