NexentaStor是一份私有操作系统，它由开源发行Nexenta的开发者创建，并被优化为作为虚拟的服务器环境及围绕ZFS文件系统创建的
Fibre
Channel应用程序来使用。它的特色包括iSCSI支持，不受限制的增长式备份，快照式镜像，块级镜像，集成于ZFS快照的搜索，以及一份用户应用编
程接口。该操作系统以ISO及VMware磁盘镜像的形式发布，其定价则基于每兆字节及每服务器的许可来决定。此外还有一份可免费获取的开发者版本供磁盘
使用空间少于4T字节的用户使用。
Garrett D'Amore has announced the release of NexentaStor 3.1, an enterprise-class storage solution built upon the foundation of the OpenSolaris-based Nexenta Core Platform: "After
a long and arduous release cycle, I am pleased to report that
NexentaStor 3.1 is available now. This release includes a number of key
features, including some significant improvements for performance and
manageability. Folks using SCSI target mode will probably see the
biggest performance boost relative to earlier versions of NexentaStor,
especially those folks using NexentaStor to serve up storage to VMware
guests -- thanks to the VAAI offload support that is part of this
release. And yes, this release includes the fix the long-standing
problem with iSCSI timeouts. For ZFS fans, this release also includes
the updates for ZFS version 28." Read the complete release announcement for further information. Download (MD5): NexentaStor-Community-3.1.0.iso.zip (580MB).
