Built around a dual-core Intel Atom CPU, Iomega's px2-300d adds hot-swap drive capability and can be configured with RAID 0 or RAID 1, as a block-level iSCSI SAN, a file-level NAS device, or both at once. Dual-Gbit Ethernet ports can be aggregated or redundant. Pricing ranges from $499 unpopulated to $1,199 with 6 TB (2 x 3 TB drives). The ix2 starts at $199 unpopulated, and houses a Marvell processor. The unit's two drive bays are not hot-swappable, and it contains just a single Gbit Ethernet port.
Both units are running LifeLine 3.4 and employ Iomega's excellent Personal Cloud software, which eliminates the complexities of web-enabling the device for sharing and data replication. EMC says the latest version of its Linux-based operating system contains the "more efficient" EXT4 file system, works better with Active Directory, supports MySQL Server and can handle video surveillance. The px NAS can handle as many as 16 cameras, and the ix can control up to eight. The px also works with EMC's Avamar data-deduplication and backup software.
