About the Deskside Disk-Array Processor Enclosure
Deskside DPE Components
The components of a deskside DPE include:
•
Front doors (two)
•
Enclosures (DPE and DAE)
•
Disk modules
•
Link control cards (LCCs)
•
Storage processors (SPs)
•
Power supplies
•
Fan packs (drive and SP)
•
Standby Power Supply (SPS)
•
Power Distribution Units (PDUs)
Any unoccupied slot (SP, LCC, disk module, or power supply) has a
filler module to maintain air flow and compliance with
electromagnetic interference (EMI) standards.
The disk modules, link control cards, power supplies, storage
processors, SPSs, and fan packs are customer-replaceable units (CRUs),
which you can add or replace without any tools while the deskside
DPE is powered up.
The high availability features for a deskside DPE include:
•
Second SP, power supply, and LCC (in the DPE enclosure)
•
Second LCC and power supply (in the DAE enclosure)
•
SPS (See “Related Documentation” on page xiii.)
A second SP (with required second LCC in the DPE enclosure)
provides continued access to the DPE and any connected DAEs if the
first SP or LCC fails. The second SP can improve performance and
connect easily to a second server.
The FC-AL compliant disk drives support dual-port Fibre Channel
connections through the link control cards and the associated cabling.
Simple serial cabling provides easy scalability, allowing you to
configure a single disk-array system using a deskside DPE and
add-on DAEs.
