Overview

The HP 4400 Scalable NAS File Services offers scalable file serving performance for medium-sized customers that cannot afford any downtime for their business-critical applications. The HP 4400 Scalable NAS File Services is a fully factory configured storage solution that includes an HP Enterprise Virtual Array 4400 (EVA4400) with dual array controllers and up to 12TB of storage standard, two high performance file serving nodes, redundant Fibre Channel switches, management and replication software, and support for Windows or Linux. The HP 4400 Scalable NAS File Services does not have a single point of failure. It allows customers to transparently increase application throughput far in excess of traditional NAS products and easily grow storage capacity online without service disruption. The HP 4400 Scalable NAS File Services offers great total cost of ownership with a low initial purchase price and a shared data architecture that yields lower management expenses from a single shared pool of file serving nodes and storage.

At the heart of the HP 4400 Scalable NAS File Services is a truly symmetrical cluster file system, with high availability services and cluster storage management services, which allow file server nodes and storage to be added to linearly scale file serving throughput performance or storage capacity. The HP 4400 Scalable NAS File Services integrates various file serving protocols including Network File System (NFS) functionality, Common Internet File System (CIFS) or SAN-Direct I/O protocol. The product can aggregate up to 16 Windows or Linux file server nodes for high-performance, fault-tolerant file serving with a EVA4400 storage.

The EVA4400, used by the HP 4400 Scalable NAS File Services, delivers all the business benefits of virtualization such as ease of management, superior capacity utilization, and self-tuning performance that have made the EVA product family one of best selling arrays in its class. The EVA4400 provides broad operating system support and is built on the EVA4400/6400/8400 architecture with dual-redundant design and offering 99.999% availability. Plus, it supports the robust local and remote replication capabilities of Business Copy and Continuous Access EVA allowing 4400 Scalable NAS File Services customers to configure for disaster tolerance and the ability to easily keep applications on-line during backup and restore.

Scale from 2 to 16 nodes with a linear increase in file serving performance and throughput. Depending on number of HDDs and application workload Support for 128 TB per file system for Linux and 32 TB per file system for Windows. The Linux version provides scalable NFS file serving and transparent failover for NFS clients with no need to remount in the event of one or more node failures. This feature is unique in the industry. The Linux version also supports CIFS file serving in a non scalable mode via Samba. The Windows version provides scalable CIFS file serving and transparent failover for CIFS clients with no need to reconnect in the event of one or more node failures. The Windows version also supports NFS file serving in a non scalable mode via Hummingbird NFS Maestro™

Fully symmetrical file system architecture means that all nodes see the same file system and that means no hot spots or bottlenecks. Hardware node failures are detected and failed over to all remaining nodes in as little as 5 seconds.

99.999 continuous availability

Complete session state, data and cache coherency is maintained among all nodes in the cluster. Both the Windows and Linux versions support scalable SAN-Direct I/O.

The performance of each node can provides up to 170 MB/second of sequential write throughput; approximately 190 MB/second sequential read throughput regardless of the base OS selected.

NOTE:

NOTE:NOTE: system.

SUSE Linux v10 Enterprise edition is the supported Linux File Server node OS versions. Windows Storage Server x64 2003 R2 is the supported Windows File Server node OS version.

Though the HP 4400 Scalable NAS File Services comes standard with an EVA4400 array storage system, it can also use any HP of SAN storage product including MSA, EVA and XP storage arrays. Utilize existing data center tools and solutions for backup, management and anti-virus protection that support the OS you have selected.

The HP 4400 Scalable NAS File Services includes pre-loaded and pre-configured file serving and array management software. Perform rolling upgrades of individual file server nodes by removing nodes from the cluster and then re-inserting them into the cluster. This can be done without any disruption to clients or concern about data integrity with the failover over capabilities that are part of the architecture.

Purchase the file serving needs for today confident that you can add additional file serving throughout put and performance as your needs grow. There is no need for a "forklift upgrade" in the future. By building the solution with industry standard components flexibility can be maintained in the infrastructure - no need to buy proprietary hardware and software. Integration in the data center is straight forward as there no need to specialized training to learn about custom hardware and proprietary software.

The HP 4400 Scalable NAS File Services supports both file and block storage access. For host block storage access the HP 4400 Scalable NAS File Services provides support for industry-leading Operating System platforms including: HP-UX, HP OpenVMS, Windows 2008, Windows 2003 Professional, Windows 2003 Standard/Enterprise (32/64-bit) and Extended (32/64-bit), /DataCenter (64-bit), Sun Solaris, Linux, IBM AIX, Novell NetWare, VMware and Apple Mac OS X.

NOTE:

See the EVA Family Operating System, Cluster and High Availability Compatibility matrix for

NOTE:NOTE: Operating System version details.

The HP 4400 Scalable NAS File Services redundant architecture is designed to eliminate single-points-offailure.

Each EVA4400 Dual array controller has ten FC host ports per controller; twenty per controller pair and two device ports per controller, four per controller pair.

Each EVA4400 controller pair interfaces with the M6412 drive enclosures. With two device ports per controller and dual FC I/O modules per drive enclosure, each controller has two connections to each FC drive A and B port. So each controller has a redundant path to each drive.

Each X5500 Network Storage Gateway node has a dual port HBA. Each HP 4400 Scalable NAS File Services system includes dual 10 port enabled FC switches. With two FC ports per HBA and two FC host ports per array controller, each node and array controller connects to each FC switch. So each node has a redundant path to each array controller and each drive within the array.

HP 4400 Scalable NAS File Services

HP 4400 Scalable NAS File ServicesHP 4400 Scalable NAS File Services

On the EVA4400, each port connects to one FC I/O module on a drive enclosure. Up to eight drive enclosures can be connected in a FC loop arrangement with a controller pair and connect to one port of up to 96 drives. With the two FC ports per controller, each controller can connect to both ports on up to 96 disk drives for redundant paths to all 96 drives.

The EVA4400 controller also has dual redundant hot plug power supplies and dual redundant hot plug blowers. Each controller has hot plug cache batteries to maintain cache contents for up to 96 hours in case of a total power failure.

The M6412 FC drive enclosure has dual redundant hot plug FC I/O modules that allow the controllers to distribute I/Os between the two modules and provides redundant paths should either FC I/O module become unavailable. The enclosure also has dual redundant hot plug power supplies and dual hot plug blowers. Environmental Monitoring Unit (EMU) functionality is built into the I/O module in the enclosure and monitors and reports the condition of the power supplies and fans.

The FC and FATA disk drives have dual FC ports which can be redundantly accessed by each controller. The drives are hot plug. Drives can be configured, using redundant Vraid1 or Vraid5 protection, so that a drive failure will not cause loss of data. Optional virtual sparing can be configured so that a drive failure will trigger an automatic rebuild of the Vraid1 or Vraid5 protection using the virtual spare.

All EVAs have dual redundant power distribution. Two independent power cords distribute power through two Power Distribution Units (PDUs) to each side of the EVA cabinets and to each power supply of the controllers and to each power supply of the drive enclosures Each cabinet power cord can be connected to independent power sources. For maximum availability, a customer should provide redundant power from independent power circuit breakers, independent power lines from the power company and even independent power companies.
