FastStream RAID Storage Controllers FAQs

Q: What is the ATTO FastStream SC?
A: ATTO FastStream Storage Controllers are high-performance devices, independent of storage which add instant data protection while enabling you to pool your direct attached storage together and access it on your Storage Area Network (SAN). Connect individual disks, JBODs or RAID systems and instantly increase performance and reliability. In addition, you can expand RAID groups and add storage on-the-fly, growing as your needs grow. The ATTO FastStream is a unique solution that leverages ATTO's engineering expertise in data management. FastStream storage controllers offer high-performance features such as hardware-based RAID, multi-host connectivity, field serviceable design, all in a standard 1U – 19" external rack or desktop form factor.

Q: Why use a FastStream Storage Controller?
A: With skyrocketing storage demands coupled with shrinking budgets, companies continue to face increasing stress on their IT infrastructures. ATTO FastStream Storage Controllers directly resolves both of these issues. By offering companies the opportunity to network their existing Direct Attached Storage (DAS) creating a manageable pool of assets with the added benefit of RAID protected data. The FastStream has the performance to meet the most demanding needs including video and film editing, audio editing and playback, database and other high throughput applications.

Q: What separates the FastStream Storage Controller from off-the-shelf RAID solutions?
A: The FastStream Storage Controller utilizes ATTO patent-pending technologies, rather than off-the-shelf RAID solutions, to provide unsurpassed performance and category-leading flexibility. The FastStream is not an integrated solution; this allows organizations to continue to add lower cost JBOD storage as their need for capacity grows without the need to purchase more expensive RAID arrays every time you need additional storage capacity. Performance, protection, capacity expansion and added intelligence to storage are the main value points of the FastStream SC line.

Q: How many drives does the FastStream Storage Controller support?
A: The FastStream SC supports up to 128 target devices.

Q: What configurations are available?
A: ATTO FastStream Stroage Controllers are available in 1U rack and desktop configurations; additionally available as an embeddable MicroATX board. Interfaces include quad 4Gb Fibre Channel to dual (x4) SAS/SATA, dual 4Gb Fibre Channel to dual 4Gb Fibre Channel disk interfaces and quad 8Gb FC to (x4) SAS/SATA and quad 6Gb SAS to (x4) SAS/SATA.

Q: What is the maximum number of hosts that can be connected per FastStream Storage Controller?
A: Fibre Channel models of the FastStream Storage Controller support up to 96 host initiators.

Q: Does the FastStream support LUN Mapping?
A: Yes, the FastStream Storage Controller supports LUN Mapping. The ability to define which servers have access to which LUNs is handled through the LUN Mapping capabilities within the FastStream. Because the FastStream has independent Fibre Channel host interfaces the user will need to define which LUNs are accessible through which port. The default is that every LUN is accessible through each port.

A: The ATTO FastStream contains redundant Fibre Channel host ports operating at 4Gb/s or 8Gb/s. The host ports support FC-AL, and point-to-point operating modes.

Q: What types and speed drives are supported by the FastStream Storage Controller?
A: The ATTO FastStream works with 3Gb and 6Gb SAS or SATA disk drives.

Q: Can my existing storage be moved away from video editing workstations and servers?
A: The FastStream Storage Controller allows you to extend the distance your storage may be located from your workstations. By utilizing the Fibre Channel ports and forming a Storage Area Network (SAN) you can pool your storage together in one location almost anywhere at your location. This reduces noise, allows faster access to all data stored and clears workstations from the physical presence of Direct Attached Storage (DAS).

Q: How does the FastStream achieve its fast performance in RAID configurations?
A: RAID applications are the most taxing on storage subsystems. These calculations (called XOR processes) ensure redundancy but are "compute intensive". The ATTO FastStream Storage Controller utilizes hardware to complete the XOR calculations. This removes the task from the processors running the storage and places the workload on components optimized for the job. ATTO uses patented technology coupled with custom software to accomplish this. ATTO has many years of RAID storage development experience that results in enhanced performance in the FastStream SC line.

Q: Is FastStream suitable for video applications?
A: The FastStream Storage Controller is optimized for video needs. The FastStream supports a wide selection of video solutions and configurations and has industry-proven results to support this. There are three key aspects to supporting a video application – 1) performance, 2) RAID protection, and 3) interoperability. The FastStream offers all three.
