The 9750-4i may support JBOD mode. If you would like to test, install the MegaCLI tools. (Warning, this will clear the RAID configuration on your device) This is the command for switching the RAID controller to JBOD mode: #megacli -AdpSetProp -EnableJBOD -1 -aAll Thanks, Jacob -----Original Message----- From: ceph-users [mailto:ceph-users-bounces@xxxxxxxxxxxxxx] On Behalf Of Markus Goldberg Sent: Thursday, April 23, 2015 5:41 AM To: ceph-users@xxxxxxxxxxxxxx Subject: SAS-Exp 9300-8i or Raid-Contr 9750-4i ? Hi, i will upgrade my existing Hardware (in 3 SC847-cases with 30 HDDs each) the next days. Should i buy a SAS-Expander 9300-8i or keep my existing Raid-Contr 9750-4i. The 9300 will give me real Jbod , the 9750 only single-disk Raids. Does this make a real difference ? Should i spend or keep money? -- MfG, Markus Goldberg -------------------------------------------------------------------------- Markus Goldberg Universität Hildesheim Rechenzentrum Tel +49 5121 88392822 Universitätsplatz 1, D-31141 Hildesheim, Germany Fax +49 5121 88392823 email goldberg@xxxxxxxxxxxxxxxxx -------------------------------------------------------------------------- _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com ---------------------------------------- The information contained in this e-mail message is intended only for the personal and confidential use of the recipient(s) named above.
