Vision 2015 Goals
 NASA will ensure safe stewardship of the data through its lifetime.
 The EOS archive holdings are regularly peer reviewed for scientific merit.
 Multiple data and metadata streams can be seamlessly combined.
 Research and value added communities use EOS data interoperably with other relevant data
and systems.
 Processing and data are mobile.
 Data access latency is no longer an impediment.
 Physical location of data storage is irrelevant.
 Finding data is based on common search engines.
 Services invoked by machine-machine interfaces.
 Custom processing provides only the data needed, the way needed.
 Open interfaces and best practice standard protocols universally employed.
 Mechanisms to collect and preserve the pedigree of derived data products are readily
available.
 Data systems evolve into components that allow a fine-grained control over cost drivers.
 Expert knowledge is readily accessible to enable researchers to understand and use the data.
 Community feedback directly to those responsible for a given system element.
 Access to all EOS data through services at least as rich as any contemporary science
information system.

Evolution status and plans for ECS:
Technology Infrastructure (Software Transition)
•
ECHO to provide user search, browse, and order submission functions
to the evolved ECS
 Warehouse Inventory Search Tool (WIST) and other ECHO clients will provide
these services
 The V0Gateway will be removed
 ECS orders will be implemented by ECHO clients using SOAP messages (via
HTTP? JMS?) to establish the ECHO WSDL Ordering Component (EWOC)
•
Data Pool drill down search interface would be retained
 Java application operating in the Tomcat Java Application Server
•
Other services retained include HDF-EOS to GeoTiff format conversion
utility (HEG) and the HEW Subsetter Appliance
•
Machine to Machine Gateway will be removed
 Still assessing the impact if this capability is removed from ECS
 Primary use of this service is by NSIDC staff
 May collaborate with LP DAAC (EDC) by providing requirements for a MTMGW
service via the ECHO client

Status and Plans for non-ECS Systems:
Technology Infrastructure (Hardware Architecture)
•
Commodity Servers
 Intel and AMD Servers with Linux OS
o
Phase two of transition in progress includes transition of data production software to
AMD servers
 Intel Servers with Windows OS
•
Enhanced Storage System to support NSIDC Storage Infrastructure
 Fiber Channel SAN (SATA and SCSI)
o
~14 TB including 3 TB to enable GLAS subsetting
 ADIC/Quantum StorNext File System (in progress)
o
Evaluating ADIC/Quantum StorNext Storage Manager as a replacement for AMASS
o
Working issue related with certification of SNSM for Copan MAID vtl
o
May need to re-evaluate the Copan MAID vtl as an archive solution
o
•
Considering disk archive solutions
Network upgrade for servers to Gigabit Ethernet
 Switchover is scheduled for October

accuracy that rivals predict methods while being faster, less
costly to implement, and less costly to maintain than any other
method

Capabilities Envisioned for Future Science Information Systems
The Technology Infusion Working Group, one of four working
groups established by the NASA-sponsored Earth Science Data
Systems Working Group (aka SEEDS), identified 10 capabilities
in their vision of what information systems must provide to
support scientific research in the future. This activity was
conducted in parallel with the formulation of the NASA EOSDIS
Evolution Vision for 2015.
The group is in the process of assessing the correlation
between their top ten capabilities and the goals identified in the
NASA EOSDIS Evolution Vision for 2015.
