- 5. …TAKE AWAY • Complex Environment • Many dependencies (SAN, Metadata, Tape Drives, Silo) • Aging Infrastructure • Puts pressure on all the dependencies • Tech refresh way over due • Archival data is difficult to access - high latency, lower bandwidth, user interfaces • Difficult to share archival data to multiple users • All too often archived data, particularly HPC simulations, is “write-once- read-never” SAN DIEGO SUPERCOMPUTER CENTER at the UNIVERSITY OF CALIFORNIA, SAN DIEGO Cyberinfrastructure Services Division
- 6. Where SDSC is at today Data Services Overview Cloud Storage (OpenStack Swift) • Purpose: Storage of Digital Data for Ubiquitous Access and High-Durability • Access Mechanisms: Swift/S3 API, Cloud Explorer, Clients, CLI Traditional File Server Storage (NFS/CIFS) • Purpose: Typical Project / User Storage Needs • Access: NFS/CIFS/iSCSI High Performance Computing Storage (PFS) • Purpose: High Performance Transient Storage to Support HPC • Access Mechanisms: Lustre on HPC Systems (Gordon, Trestles, Triton) SAN DIEGO SUPERCOMPUTER CENTER at the UNIVERSITY OF CALIFORNIA, SAN DIEGO Cyberinfrastructure Services Division
- 7. Goals for Cloud/Object Storage • Support NSF Data Management Plan • Required Plan to describe how research results are shared. • 99.5% system availability • File replication automated • Default 2 copies, able to keep additional offsite replications. • Automated checksum verification and error correction • Scalable • Performance and capacity grows by incremental bricks. • Multifaceted accessibility • Web, API, Graphical and Command Line Clients • Cost competitive • Operated as a recharge service • On par with current tape-based dual-copy costs of $0.0325/GB/Mo. SAN DIEGO SUPERCOMPUTER CENTER at the UNIVERSITY OF CALIFORNIA, SAN DIEGO Cyberinfrastructure Services Division
- 8. Why Openstack? Industry Standard Proven Software • More than 100 leading • Running the OpenStack cloud companies from over a dozen operating system is same countries are participating in software that powers many OpenStack, including large public and private Cisco, Citrix, Dell, Intel and clouds, including RackSpace Microsoft Cloud Storage. Control & Flexibility Highly Compatible Open source platform means not • Compatibility w/ public OpenStack locked to a proprietary clouds means it’s easy to migrate vendor, and modular design can data and apps to public clouds integrate with legacy or 3rd-party when desired—based on security technologies. OpenStack project policies, economics, and other provided under Apache 2.0 key business criteria license.

Notas del editor
- Organized research unit on the campus of UC San Diego and funded by the National Science Foundation.
- Describe environment, Complex, Latency due to tape loads, small files affect performance
- Silo overview, pass-through ports
- High latency tape access and lower bandwidth users wait longer for there data. Many times one user can monopolize the staging queueBecause it’s difficult to share and access, most data tends to be write-once, ready never. Fine for things like backup, but not acceptable for valuable data sets
- Where we’re at
- New January 2011, NSF data plan is required for all new grant proposals
- Talk about basic architecture, scale out by adding more components (proxies, storage bricks) Love the shared nothing architecture. then changes we made to improveDoug Merging auth, Load balancing… Arista switched data oasis…Currently running Centos 5 with a plan to update to Centos 6.2 within the next couple of months.
- Launched Service in August 2011, Modest usage so far. Commvault backup service has yet to come online
- Backups consumes the most space and This is consistent with our tape archive usage as wellFollowed by File system emulation. Both Backups and Filesystem are well understood and have familiar applicationsNative Client usage is a small percentage of use (swift python client, cyberduck, cloud explorer). There is no robust reliable (free) client available to our knowledge. We would like to see this get addressed. Speak to the challenges of each tool.We may be a little different in where we want to use swift as the generic storage service vs building an application.

- Search, indexing,etc is handled by the web applicationDigital assets, text and other associated data is stored in swift
- Features: Upload, Download, Permissions, dragNdrop, change passwordNot considered a large data movement tool. Largely used for viewing objects, setting permissions, viewing share URL’sNeed to support large file uploads
- Swift: Nice to add copy, move, rename. In general, we’d like to see a robust command line client. We are interested in starting this effort if one doesn’t exist already and talking to others who have similar needsNearly all of our HPC users rely on command line based tools. Cyberduck is ok for light usage. Our hopes is that once cloud explorer supports drag and drop uploads that this would obsolete the tool and focus on the web and command line tool development and support.
- And with that I’ll take questions

- Ron PI pertinentEverything you put in is immediately shareable to groups of users, the world or no one if you want This form of storage is fully integrated with your applications and web services.Near real time collaboration from anywhere on the globe that you have web access.
