Storage systems that use the ZFS file system, a transactional data system developed by Sun Microsystems, have their own hardware-controller-free RAID function. They also ensure extremely high data security thanks to file system checksums and periodical disk scrubbing. Configured as a cluster, ZFS servers access a shared storage pool. To ensure protection even if a complete JBOD fails, the disks of two JBODs are mirrored against each other. The data can then be made available for the clients via iSCSI, NFS and CIFS. At this year’s CeBIT, EUROstor is presenting the first ever Metro Cluster solution using Open-E JovianDSS software. The cluster nodes do not access the JBODs as usual via SAS, but instead via fiber channel. This means the two cluster nodes and one half of the storage pool in each case can be placed in two different fire protection areas. FC switches even make long-range distances possible.

At the other end of the scale, EUROstor is also presenting a ZFS cluster-in-a-box. In this case, both cluster nodes are compactly housed in a chassis of 2 or 4 U and access a common backplane. Here, too, both nodes can be rebooted separately without interrupting data availability. "With these two new ZFS products we are able to considerably expand the fields of application for clusters with Open-E JovianDSS," says EUROstor’s Managing Director, Franz Bochtler. "With the ES-8700CLF Metro Cluster we are able to present to our customers a very reliable and, nevertheless, affordable high-availability solution."
