Sun Microsystems Keynote: NFS for N1
- Glenn Weinberg, Director, Software Engineering, Sun Microsystems With the release of Solaris 9 in May, Sun announced the N1 architecture. N1 is a new computing architecture that virtualizes an entire data center of servers, storage, and network computing equipment as if it were one super-server. N1 storage emphasizes IP networking and file-based access, with NFS as a key component. This presentation makes the case to move file-based data access and NFS from an optional role, to a vital role in the data path. |
| 9:45-10:30am |
High Performance and Distributed NAS Server Architecture for Scalable
and Global NFS file systems
- Mike Kazar, CTO, Spinnaker Networks Many different architectures exist in the marketplace today to provide NFS file serving, from NAS to general-purpose systems with DAS. This presentation will discuss a new NAS architecture from Spinnaker Networks, based upon a distribute file system which enables the IT administrator to build large, high performance NFS file systems with a global name space. |

| 10:45-11:15am |
NFS version 4
- Spencer Shepler, Sun Microsystems RFC3010 was the start. Implementations were started, issues were found. The update to RFC3010 (NFS version 4) is complete and coming to an RFC list near you. Will take a look at where the NFS version 4 implementation community is currently at and what changed from RFC3010 and where the NFS version 4 standard is going. |
| 12:00-12:30pm |
NFSv4 Open Source Reference Implementation Project Update

Hummingbird Keynote: Hummingbird NFS Maestro = NFSv4
- Dan Trufasiu, Director of Connectivity R&D, Hummingbird What does the NFS protocol offer the Windows PC world? What is the bottom line on NFSv3? Topics discussed will include Hummingbird's implementation of NFSv4: what has been done, how it was done, and the restrictions of the implementation. |
| 2:00-2:30pm |
NFS at 10Gb/sec
- Brent Callaghan, Sun Microsystems While NFS enjoys the ubiquity and interoperability of TCP/IP networking, it is facing a growing performance barrier inherent in the architecture of host networking stacks. Clients and servers are unable to keep up with a "fire hose" of data. RDMA provides direct data placement and network offload into hardware, decoupling network performance from host performance. NFS can use RDMA to take full advantage of the performance benefits of multi-Gigabit Ethernet and Infiniband networks. This presentation will describe RDMA, how NFS will use it, and how it will affect the balance of SAN vs NAS storage. |
| 2:30-3:00pm |
Network Adapters for NFS at 10Gb and Beyond
- Tom Hotchkiss VP, Engineering, Emulex NFS will require Network Adapter support to run at 10Gb and beyond. Hardware offload and new protocols such as RDMA will be required to address the shortcomings of today's approach. Multi-protocol Network Adapters interoperate with existing protocols and provide a migration path to RDMA and other future technologies. |
| 3:00-3:30pm | BREAK |
| 3:30-4:00pm |
NFS Clustered Filesystem
- Xiaoye Jiang, EMC Scaling NFS server throughput can be accomplished in several ways; most commonly NFS servers approach the challenge of scaling by devoting larger and larger machines to the task, which creates larger single points of failure. An alternate approach to achieving scalability is using multiple servers in a cluster configuration. This approach has not been widely adopted because of the challenge of maintaining cache coherency between the nodes. Leveraging MPFS technology natively on EMC Celerra NFS servers allows you to build incrementally scalable amounts of front-end capacity to a shared filesystem. This allows you to treat your NFS serving requirements much like you treat your storage requirements, scaling incrementally to meet your front-end I/O requirements. |
| 4:00-4:30pm |
NFS v4 - Customer problems and NetApp's solutions
- Amit Sinha, Multiprotocol Product Marketing Manager, Network Appliance A brief overview of typical customer NFS environment, their current challenges with NFS v2 and v3. It will then lead to how NFS v4 will benefit these customers and their environments, for example security, performance. In addition, the presentation will also focus on how NetApp is driving the NFS v4 development efforts with partnerships from leading NFS v4 client vendors. |
| 4:30-5:00pm |
Migrating from AFS to NFS for Global Data Sharing
- Travis Broughton, Intel For the past decade, Intel has been using AFS to share design data globally, with NFS (protocol versions 2 and 3) used to provide higher performance for data with no inter-site access requirements. With the EOL of AFS announced by IBM, we have been examining other technologies to provide global access to data, including OpenAFS, NFS (protocol versions 3 and 4), and caching NFS proxy solutions. This presentation will describe the existing AFS-based environment, the advantages we see in NFS (especially NFSv4), and the challenges -- both technical and political -- that we are facing when considering migrating to NFS-based solutions. |

EMC Keynote: Policy Based Management and Tiered Backends
- John Hayden, EMC Storage platforms are becoming more and more a commodity available at specific tiered levels - running the gamut from JBOD to simple RAID arrays, to complete storage subsystems with integrated features such as replication and snapshots. NAS devices, attached to these different tiers of storage from many different vendors, are presented with new and unique management and functionality challenges. Tools and strategies to manage the transparent storage provisioning and migration of data from one tier to another, as well as policy based engines to automatically match business requirements (service level agreements, recoverability, replication, performance, availability etc.) to the available storage tiers are needed in such environments. |
| 9:45-10:30am |
Analyzing NFS Client Performance with IOzone
- Tom McNeal, TRM Consultants and Don Capps, Hewlett-Packard This paper will review the basic structure of IOzone, a file system benchmark which may be used for assessing client performance issues in an NFS client/server environment. It will review IOzone's use of file IO for its base measurements, and will discuss possible system and network variations based on IO type, SMP, cache management, process vs. thread usage, transport type, etc. It will also review the system parameters useful in modifying system behavior when testing with IOzone, in order to investigate client behavior in the most extensive and illustrative way. |

NFS: Pushing the Limit
- Smita Thakur, Sun Microsystems |
| 11:15-12:00pm |
Deploying Scalable Switched NAS Infrastructures within NFS Environments
- Vladimir Miloushev, CTO and Founder, Z-force Z-force has invented a new network node called a "file switch". The "file switch" will enable the first "NAS Array", an unlimited number of commodity, low-cost NAS boxes that can be connected together to provide aggregated performance and unlimited scalability at up to wire speeds, in an environment that is truly manageable as a single entity. This session will discuss the file switch in more detail and the challenges with switching file transactions at wire speeds. It will look at the NFS protocol and its strengths and limitations for large fileserving environments. The session will look at the unique issues associated with NFS interoperability, security and locking mechanisms to provide an aggregated NAS environment. |
| 12:00-12:30pm |
NFS-v4 server implementation in a multi-protocol environment
- Dave Noveck, Network Appliance A discussion of the Netapp filer's NFS-v4 implementation will be presented. The implementation of such features as locking support, ACL's, and named attributes will be discussed. The focus will be on the choices and tradeoff's concerned with multiprotocol implementation -- what implementation is protocol-specific and what generic to multi protocol. There will also be discussion of possible implementation strategies for future features such as delegations and migration support. |

| 2:00-2:30pm |
Managing NFS in Solaris using CIM/WBEM
- Sarah Jelinek, Sun Microsystems CIM/WBEM is a technology that is gaining ground in the data resource management area. Many vendors, including Sun Microsystems, are planning on rolling out data resource management products based on the DMTF CIM and SNIA Bluefin specifications. NFS in Solaris will be fully manageable via CIM/WBEM. This talk will present the full Solaris NFS CIM model, along with examples on how to use it in Solaris. |
| 2:30-3:00pm |
Replication and Migration
