Product Snapshot #4
Product: Exanet; ExaStore NAS management software
Maximum Storage: ExaStore clustered NAS system has no practical limits on capacity, file size, or number of files. It can scale transparently to any total capacity, up to 1 Exabyte. Storage space can easily be expanded, through the addition of disks or entire storage arrays. The file system grows to include the new storage without disrupting user access to data.
RAID Support: Different RAID arrays are supported in different configurations – 0, 1, 0+1, 5, 6. There is a required minimum of 2 LUNs per ExaStore cluster node, and a recommendation of a minimum of one LUN per CPU core (so in a Quad-CPU node it is recommended to configure access to a minimum of 4 LUNs).
Hot Spare Support: Hot spare support will depend on the underlying RAID array – all RAID arrays that Exanet supports currently do support hot spare disks.
Automated Discovery: ExaStore automatically discovers LUNs from RAID arrays.
Automated Maintenance: Most system maintenance activities, including hardware and software upgrades, are performed on-line, with no down time. ExaStore is designed to be fully supported remotely, and includes a built-in "phone home" capability, which continuously monitors the health of the system, and alerts Exanet's global support center to any problem. The file system itself automatically distributes data among the cluster nodes, and is self-tuning, requiring no performance tuning from the administrator.
Reporting Features: ExaStore includes a centralized, browser-based tool for managing the system. The tool monitors and controls capacity utilization, performance, configuration, and hardware system status. Using SNMP support, it integrates easily into standard system management frameworks, such as OpenView (HP) and Tivoli (IBM). A CLI interface is also provided. ExaStore authenticates users via Active Directory, LDAP and NIS.
Backup Support: ExaStore can be easily integrated with any network environment, and with major backup products from Veritas, Legato, CA, and others, using vendor-provided backup agents. ExaStore offers a variety of connectivity options for backup: Through the client network to a backup server; over a dedicated "backup-only" network to a backup server; or using a direct FC or SCSI system-to-tape connection. The ExaSync feature enables backup to disk, ensuring very fast, highly reliable, automatic backup and recovery.
Virtualization Support: All information in an ExaStore system is contained in a single global file system. A client needs to only configure access to one file system to gain access to any of the data in the system. The ExaFS distributed file system is the core infrastructure that turns the multi-node ExaStore system into a single-system image. Each node in a system is a peer and presents an identical view of the file system. Both data and metadata are fully distributed. In addition, ExaFS supports virtual data container entities called virtual volumes which allow the administrator to apply different capacity allocation, security, and data protection policies to every data set separately.
Security Features: ExaStore is released as a secure platform – supporting SSH/SSL protocols for management. In addition, it supports common file sharing authentication protocols such as Active Directory, NIS and LDAP.
Other Key Features: ExaFS supports file striping, directory striping and metadata striping out-of-the-box, without any additional configuration or licensing; ExaStore active/active software architecture uses redundant pairs in a clustered configuration, and a patented transparent failover architecture protects file access in case of hardware failure; offers automatic and transparent capacity and client load balancing; ExaStore CDP gives administrators access to a virtually infinite set of data recovery points, through the use of unlimited Snapshots. These can capture block-level changes on a continuous basis, reducing capacity requirements by capturing only the portion of the files that has changed.
Minimum Requirements: Supported PC hardware with a minimum of 4GB per node, a minimum of 2 nodes, and a supported RAID array.
Hardware Compatibility: Standard, Intel-based Linux servers comprise the nodes of the ExaStore cluster, and ExaStore supports a variety of standard, off-the-shelf RAID subsystems. Complete list of supported hardware at: http://www.exanet.com/default.asp?contentID=41
OS Compatibility: ExaStore is natively compatible with NFS, CIFS, and AFP file protocols, enabling Windows, Linux, UNIX and Apple Macintosh OS9/OSX users to freely share data with one another.
Vendor Comment: ExaStore's intrinsic value lies in its internally developed file system and NAS software, which optimize the performance of industry-standard components. ExaStore is unlimited by design, enabling it to scale to arbitrarily very large systems while maintaining excellent performance, high utilization, and ease of use.
