1、Share rich media in a high-speed, cross-platform SAN Enable your Mac, PC, and Linux workstations to simultaneously read/write common files at hundreds of megabytes per second! What is a SAN? A Storage Area Network (SAN) allows multiple computers to simultaneously attach to a common storage device. A

2、 SAN overcomes the performance bottleneck associated with traditional NAS (Network Attached Storage) and server-clients technologies SAN management software (such as metaSAN) is required to arbitrate accesses and prevent file system corruption that would normally occur when multiple computers attemp

3、t to write to the same volume 2/33 Volume-level sharing Traditional volume-level solutions grant write access to a given volume to only one user at a time. Others can only read. LAN SAN Read only Read only Read server virtualization transparently aggregates the bandwidth of multiple servers. By allo

4、wing multiple servers to appear as a single cluster to LAN clients, reliability and up time is increased and maintenance of the individual servers is greatly simplified. 22/33 Is server virtualization right for you? Do you have need for: High seat count with moderate bandwidth requirements Reliable

5、connection to the shared storage Block-level access from LAN clients Easy cross-platform integration Simplified maintenance of your network 23/33 Top 5 reasons for choosing metaLAN 1. New generation of clustering software Any SAN member (metaSAN, metaSAN iSCSI, or metaLAN Server) can participate in

6、a cluster of servers for metaLAN clients Provides the scalability and reliability required to simplify and unify data centers Complete integration with standard IT management tools Save $ on Microsoft Client Access Licenses (CALs) 2. Dynamic Load Balancing and failover for LAN clients Aggregates the

7、 total bandwidth of individual LAN servers to eliminate hotspots and I/O bottlenecks Dynamically reassign LAN connections based on server load Eliminates single point of failure found in server/clients model Supports Link Aggregation (aka trunking) for increased bandwidth 24/33 Top 5 reasons for cho

8、osing metaLAN 3. Unique cross-platform integration Windows, Mac, and Linux workstations easily join the cluster Built-in file-system translation technology ensures everyone can read and write the same files No visible performance impact to foreign clients 4. Benefit from advanced metaSAN features on

9、 LAN clients Block-level access to data Per-node bandwidth usage control Virtualization for Avid 25/33 Top 5 reasons for choosing metaLAN 5. Uses a native file system (HFS+ or NTFS) Your SAN is Easier to setup, maintain, and support Choose the file system you are most comfortable with No need to re-

10、format your RAID Your SAN volume can be disconnected and used as local drive Your entire SAN is easier to install, manage, and support Use standard tools to format and/or configure SAN storage Supports large volumes (16TB) Supports software RAID 0 striping for optimal performance No need to create d

11、edicated metadata partitions Standard tools can be used to diagnose, defrag, and repair damaged volumes 26/33 metaLAN Server vs. metaSAN Offers virtually all the same features, but at a reduced price Difference: SAN volume does not mount locally on metaLAN Server desktop SAN volume available on the

12、metadata master machine only Volume will disappear after failover Cannot be used for reliable backup Cannot be used for creating regular network shares after failover Use metaSAN instead when this functionality is required metaLAN Server is designed to be used as a gateway server for metaLAN clients

13、 Available for Windows or Mac OS metaSAN and metaLAN Server licenses cannot be used in the same setup 27/33 Dynamic load balancing Dynamic load balancing eliminates i/o bottlenecks and hot spots by distributing client load between the servers SAN LAN Server A Server B Server C Gigabit Ethernet Share

14、d Storage Fibre Channel, iSCSI, AoE, or InfiniBand 28/33 Transparent failover Total bandwidth is reduced when a server fails (or is taken off-line for maintenance) but clients do not lose access LAN Server A Server B Server C Gigabit Ethernet SAN Shared Storage Fibre Channel, iSCSI, AoE, or InfiniBand 29/33 The most flexible SAN technology! 30/33
