Need for Super Storage Application ServerNeed for Super Storage Application Server

Companies willing to spend more for larger servers [Forrester]– Server spending driven by

consolidation [$90B 2003;IDC]

Rapid market growth - NAS CAGR 133%; Appliance CAGR 73% [SRC]


GoalGoal

Build a super file server that provides an order of magnitude performance and scalability improvement over the state-of-the-art File servers

Lower total cost of operations Manage fewer servers Lower management cost and complexity Support incremental scalability

Improve service quality Provide QoS guarantees Provide carrier-class reliability


SSA Features / BenefitsSSA Features / Benefits

Unprecedented system scalability and throughput performance

Carrier class reliability for supporting SLAs Centralized multi-customer management with lower TCO

for provisioning Customer specific Performance, Fault, and Address

isolation Hot pluggable, incremental scalability Support for multiple LAN/WAN/Storage interfaces Support for Greenfield and Legacy customers


Target CustomersTarget Customers

Data centers that require demanding performance (capacity, throughput, reliability) from incrementally scaleable centralized storage initiatives– Enterprise data centers for the Financial services industry

(E-Trade, Merryl Lynch, Goldman Sachs), Oil/Gas exploration, etc.

– Storage service providers

– Intranet data centers of medium/large enterprises


Why File ServersWhy File Servers

Ubiquitous abstraction familiar to users and application developers– Commonly used functionality - needed by web-

servers, application-servers, database servers, client’s, etc.

– Standardized protocols allow adoption of new servers without changes to client/application code

Problems with today’s deploymentProblems with today’s deployment

Server attached storage difficult to manage– Detrimental to storage consolidation initiatives

– Operational cost too high Server attached centralization software is

inefficient– 30% overhead (FS + VM) for each server

– Difficult to upgrade

Difficulties scaling GPC File ServersDifficulties scaling GPC File Servers

GPC based file servers are difficult to scale (I.e., performance and capacity)– Processor is on the data path

– Memory/bus bandwidth contention

– Sequential processing of operations

– No specialized resources to accelerate data/control path

New thinking is required to resolve the file server bottleneck


Technical ApproachTechnical Approach

Strategic: Do to GPC file servers what Cisco did to GPC routers– Eliminate File system bottlenecks with specialized

hardware and software resources

Tactical: Break file server operations into primitives Distribute primitives over a switched interconnect Configure/deploy primitives dynamically (n-

tiered) to provide functionality– Pipelined/Parallel execution of primitives


The NGFS Logical ArchitectureThe NGFS Logical Architecture

• Uses a switched networking core

– Eliminates the storage bandwidth limitations of conventional servers

• Separates data and control paths

– Increases scalability

– Increases throughput

– Reduces latency• Acceleration used in both the

data and control paths

– protocol stack processing on network service modules

– directory operations (e.g. filename search) on the file system service modules
