GENERAL DESCRIPTION

EEC1005 is a generic, easily configurable, True Universal Backplane Management (UBM) device that can be used on

hard drive backplanes to provide complete storage enclosure management and reporting to computing host systems

using industry standard communication protocols.

EEC1005 supports a variety of host interfaces to accommodate SAS/SATS/NVMe backplane. The SFF-8654 slimline

connector (Host facing Connector) can be used to route SAS signals in which case the HBA will manage SAS/SATA

drives, the same connector protocol (physically a different connector) can be used to route PCIe signals in which case

the HBA will manage NVME drives. In both cases UBM will be used as management protocol with support of SGPIO

as well on SAS Slimline (Configuration dependent).The device supports using U.2 and U.3 Drive facing Connectors.

EEC1005 also supports Multiple Backplanes on a single chassis.

EEC1005 supports 2 or 3 LED IBPI blinking patterns for up to 16 drives. Customized LED blink pattern can also be pro-

grammed through the FRU.

The EEC1005 has a secure boot loader that authenticates and decrypts the Flash boot image (UBM application) using

the AES-256, ECDSA P-256, SHA-256 cryptographic hardware accelerators. EEC1005 hardware accelerators support

128-bit and 256-bit AES encryption, ECDSA and EC_KCDSA signing algorithms, 1024-bits to 4096-bits RSA and

Elliptic asymmetric public key algorithms, and a True Random Number Generator (TRNG). Additionally, the device

offers lockable OTP storage for private keys and IDs.

EEC1005 is available in 84 pin and 144 pin WFBGA packages.
