Преимущества
Performance Leadership
The AAC-364's I/O capacity and throughput are more than a match for even the most data-intensive applications. Its on-board StrongARM RISC microprocessor and 64-bit data path deliver the power and bandwidth to drive up to 60 devices over 4 Ultra2 SCSI channels. The AAC-364 can achieve sustained data rates in excess of 200 Mbytes/sec and 28,000 I/O's per second (IOPS). Additionally, its unique design significantly reduces I/O latency and host CPU utilization for I/O processing.
Data And Investment Protection
In addition to the data availability of RAID, the AAC-364 provides disk failover facilities to ensure uninterrupted access to data. When a drive fails, a designated spare takes over automatically and data is reconstructed in real time. The AAC-364 also includes a non-volatile cache memory card that supports up to 128 MByte of industry-standard ECC memory. This removable daughter card includes battery-backup to preserve cached data for up to 72 hours in the event of a failure. Best of all, cached data can be easily restored by transferring the daughter card from the failed system to another AAC-364 controller. The AAC-364 also protects your IT investments. With 4 Ultra2 SCSI channels, the AAC-364 delivers more storage capacity to your server systems by allowing you to configure more devices per server PCI slot. The AAC-364 is also 32-bit PCI-compatible, so it's the perfect fit for the newest 64-bit servers, as well as your existing 32-bit systems.
Easy Configuration And Management
The AAC-364 takes the complexity out of RAID. Adaptec's flexible array management software provides a graphical user interface and wizards for simple, point-and-click RAID array creation and management. System administrators can also manage storage remotely and create management scripts for automating routine management functions.
Storage Management With No Downtime
Planned downtime for storage reconfiguration and backup is a routine and costly disruption that every IS manager would like to eliminate. With the AAC-364 they can. The AAC-364's on-line management tools enable administrators to manage storage without taking systems or information off-line. Administrators can perform on-line capacity expansion (OCE) and any-to-any array reconfigurations; without interrupting user access to data. There is no system downtime and no reboot required. These on-line storage management capabilities, which are typically found only in expensive mainframe storage solutions, are the perfect solution for reducing information downtime.
