Hi, It's my understanding that CAM doesn't bundle the new ST6x40 firmware (7.1) at this point. However, the new firmware is available today by request and it does remove the 2TB limitation for the 6140 and 6540. As Andy had suggested, it does require a new version of CAM though, 6.1.
The ST25x0 firmware that fixes the 2TB limitation is still coming though. Regards. -------- Original Message -------- Subject: Re: [zfs-discuss] ZFS and Sun Disk arrays - Opinions?
