Introduction
This chapter provides a brief description of new features, minimum hardware and software levels,
and the compatibility requirements for the release of the UltraNet Edge Storage Router 3000.
What’s New With the Release
Version 3.2 of the UltraNet Edge Storage Router 3000 software adds the following new features
and enhancements.
RoHS Compliant 10/100 Ethernet Card
Environmental concerns and the desire to protect human health, has led the EU (European Union)
to issue the Restriction of Hazardous Substances (RoHS) directive. RoHS eliminates or restricts the
use of lead (Pb) and other hazardous substances in electronic products. To comply with RoHS, a
new 10/100 Ethernet card is now available.
Refer to “RoHS Compliant 10/100 Ethernet Card Requirements” under Compatibility
Requirements for more information.
FICON Tape Read Pipelining Feature
FICON Tape Read Pipelining improves performance for certain applications when reading from
FICON Tape over extended distances. FICON Tape Read Pipelining reads data from tape directly
from the tape device. Reading of tape continues until a threshold is reached. The buffered data is
forwarded to the host in response to requests from the host. When the host sends the status accept
frame indicating that the data was delivered, the read processing on the device side credits the
pipeline and requests more data from the tape. If exception status is received from the device, the
reading of data and emulation would be terminated.
Adaptive Rate Limiting Feature
The adaptive rate limiting feature allows the allocation of idle bandwidth within the network.
Often times, the bandwidth for the network is allocated in a worst case scenario when all devices
