24 April 2009 Source: www.thecus.com
Thecus' promise to users is continuous and flawless access to data. Great news for office users. The hottest storage products for enterprises, the Thecus N7700 and N8800, provide 24/7 data access with zero down-time, even during RAID upgrade and capacity expansion.
Thecus offers a convenient and accessible process when adjusting RAID level and capacity to meet all storage demands. In addition to the failover mechanism, the connection with the system is assured without compromise.
Often when system administrators would like to raise the degree of data protection by upgrading RAID level or expanding capacity by replacing hard drive disks, which can be long processes, the system is not accessible until processes are completed. This is not a desirable situation for enterprise users. With the features of RAID migration and expansion, Thecus users can read from or write into the system under any circumstances. In case of unexpected network connection, Thecus provides dual Gigabit LAN port design and the function of failover so an additional LAN port is ready for replacement if current LAN connection has problem. Below is how all features work:
Online RAID migration: if users want to upgrade the current RAID level, from RAID 1 to RAID 5 for example, simply select the desired RAID level from the web UI. During the process, users can still read or write files on the system.
Online RAID expansion: when replacing with bigger capacity hard drive disks, RAID volume will have to be rebuilt in order to maintain existing data. During rebuilding and expansion, regular data tasks are still functional.
Failover: with dual Gigabit port design, users can connect both LAN ports at the back of the system. If one LAN port fails, the other one will automatically take over the connection task to ensure continuous transfer.
On top of the unprecedented data protection, ultimate performance and vast fascinating features, Thecus N7700 and N8800 deliver continuous and flawless data access anytime and anywhere. With online RAID migration and expansion plus mechanism of failover, zero system down-time under any circumstances is guaranteed.
