Are you ready? Let's read!
About Xserve RAID
Xserve RAID is a well-designed module that provides multiple points of failover and hot-swap capability. Among all vendors of enterprise-quality RAID arrays, this option is more cost-effective, but at the same time reliable and stable. It can be used on Unix Network File System, Apple File Sharing, and Windows Server Message Block shared folder. The Network card is integrated with a Fiber Channel connector for direct connection to the Xserve, and there is also an Ethernet port used to manage the RAID server. There is also a battery for backing up disk cache and a removable power supply.
When a RAID set is created, the RAID block performs a block-by-block consistency check. At this time, the volume becomes unavailable by default. If you need the volume to be available immediately after the set is created, the array performance will be sluggish, and perhaps part of the volume will be unavailable. After completing the consistency check, you should reboot the disk.
The Xserve has its own processors and operates independently of the server. That is, you can connect one server to each controller and share the Xserve RAID.
The advanced features of the RAID administration program are as follows:
- partitioning an array into multiple volumes,
- recovering parity information in the event of a disk failure,
- expanding a volume,
- restricting access to specific hosts.
It should be noted that the Xserv3 is clearly corporate-quality while maintaining low initial cost, power consumption, and heat dissipation.
RAID data safety
Any array is subject to collapse to one degree or another, even if it is maximally fault-tolerant. If this happens to you, don't panic, you can still recover data from the array. It is for such cases that leading IT specialists have developed the DiskInternals RAID Recovery application - this utility supports both automatic and manual determination of basic parameters. It concerns the array level, type of RAID controller, disk order, size stripes, etc.
A reliable and smart recovery wizard will help you if you have little knowledge of how to recover a damaged array of any level. If desired, any virtual disk can be easily mounted on a local disk and all recovered data is exported to local or remote locations (including FTP). So you won't find a better deal at the moment for recovering any data from an array!
Follow these instructions for professional, fast, and high-quality array recovery:
- Download and install DiskInternals RAID Recovery on your computer and then open the application. Run the Recovery Wizard (if you do not need a wizard, skip this step right away).
- Select an array for subsequent scanning and search for damaged and deleted data.
- Select the search mode: Deep (for detailed view), Fast (shallow).
- After scanning, view all or individual search results for free. This way you can check the integrity and correctness of the data.
- Then purchase a license from the program website to complete the export of data to the desired storage device.
