Convert them into RAID0.<br> <br> Ахобадзе Александр<br> <a href="mailto:akh...@ri...">akh...@ri...</a><br> <br> ======================================================<br> Вы писали 20 декабря 2015 г., 9:26:56:<br> ======================================================<br> <br> <span style=" font-family:'arial'; font-size: 11pt;">Hi All<br> <span style=" font-family:'Courier New'; font-size: 9pt;"><br> <span style=" font-family:'arial'; font-size: 11pt;">I have a discussion.<br> <span style=" font-family:'Courier New'; font-size: 9pt;"><br> <span style=" font-family:'arial'; font-size: 11pt;">Now i used two mfs chuckserver to save Jboss log data . Server A and Server B. and mfs had good performance.<br> <span style=" font-family:'Courier New'; font-size: 9pt;"><br> <span style=" font-family:'arial'; font-size: 11pt;">Server A : 3 hard disk (each 2T Raid 5)<br> Server B : 3 hard disk (each 500G Raid 5)<br> <span style=" font-family:'Courier New'; font-size: 9pt;"><br> <span style=" font-family:'arial'; font-size: 11pt;">i have a thought. why not remove server's raid and directly use each disk for mfs chuck.<br> the reason is:<br> 1, Raid is mostly used for keep data safe. But mfs already did it if you choose a good copy number.<br> 2, Raid let the disk write slower than no raid for each disk.<br> 3. Remove raid can got more disk space for mfs chuck.<br> <span style=" font-family:'Courier New'; font-size: 9pt;"><br> <span style=" font-family:'arial'; font-size: 11pt;">am i right? hope got response.</body> |
