—agami Systems, which introduced its agami Information Server (AIS) NAS product approximately 18 months ago, has added iSCSI support to the AIS operating system. The new OS leverages agami's file-system features to enable snapshots, replication, and high-availability features for block-level data.
agami's unified storage system enables users to run file-based NAS and IP SAN (iSCSI ) on the same box. The iSCSI function supports more than 1,000 concurrent initiators and up to 256 targets per box. Users can configure an iSCSI target and can subsequently increase the target's capacity without service interruptions. New targets can also be added without disruption.
"One of our value propositions in our NAS offering was high throughput," claims Paul Speciale, vice president of product management for agami. "A lab validated 1GBps on our NAS product last year. We're doing the same validation on the iSCSI product and we expect it to come very close to 1GBps, if not over."
Speciale says one of agami's retail customers uses AIS systems for file storage and also wants to be able to consolidate its Microsoft Exchange on the same box. AIS is designed to offer storage consolidation and the ability to manage fewer boxes with high performance and low cost of ownership.
Contributing to low cost of ownership is an architecture that allows capacity density. agami uses SATA drives from Western Digital that are spec'd at a mean time between failure (MTBF) rating of one million hours. In addition, systems monitoring and parallel RAID schemes are designed for fast rebuild times.
Six AIS models range from 4TB to 24TB, with prices ranging from $25,000 to $100,000. Replication and fail-over are optional features.
