Product Highlights

High Levels of Storage Density, Data Protection, and Functionality

Storage Capacity - The Modular Smart Array 20 cabinet supports up to twelve SATA 3G hard drives, for a maximum of 12 TB of storage capacity using HP 1TB SATA 3G 3.5" hard drives.
- (3G SATA drives will only function as 1.5G drives in a MSA20)
Data Protection - Modular Smart Array 20 is designed for a high level of data protection. It includes redundant fans and power supplies (standard), battery-backed cache, and support for various RAID level including RAID ADG (RAID ADG within the enclosure only applies when connected to a SA6402 or SA6404, controller. When connected to a MSA1500 the RAID ADG function is performed in the MSA1500 controller.)
Storage Manageability - The Smart Array 20 feature familiar configuration and management tools such as Smart Array Configuration Utility and Insight Manager. Online Management Features: Online Capacity Expansion, Online RAID Level Migration, Online Stripe Size Migration, Online Spares (Global), User Selectable Read/Write cache, User Selectable Expand and Rebuild Priority. (These features are available only when connected to a SA6402, SA642 and 6i controller.)
Choice of Computing Platform - The Modular Smart Array 20 is designed and qualified for ProLiant servers.
Advanced Data Guarding (RAID 6 with ADG) Fault Tolerance - This is the highest level of RAID fault tolerance. It allocates two sets of parity data across drives and allows simultaneous write operations. This level of fault tolerance can withstand two simultaneous drive failures without downtime or data loss. (Only available when NOT connected to a MSA1500.)

Low Total Cost of Ownership

The modular, scalable design of the Modular Smart Array 20 provides an extremely flexible platform. You can buy what you need today and purchase additional capacity as your data storage needs grow, instead of making a large up-front investment. Additional drives and enclosures can be easily added as your needs dictate.

Tiered Storage – Improve storage utilization and lower storage management cost by moving low-IO storage applications to the Modular Smart Array 20 allowing you to more effectively utilize mission critical storage where you need it most.
Universal SATA Hard Drive – Since the Modular Smart Array 20 supports HP Universal SATA drives, your investment in disk drives is protected and cost is minimized as you add new drives. Sharing of a common universal drive form factor between your server and storage can significantly reduce needs for hardware and spare inventory, and offer overall reduction in storage management and business costs. SATA drives carry a 1 year warranty.
Pre-Failure Warranty – Drives installed in a Modular Smart Array 20 and monitored under Insight Manager are supported by a Pre-Failure (replacement) Warranty (1 year for SATA drives).. Pre-Failure Warranty allows for the replacement of designated drives in Modular Smart Array 20 before they actually fail when using Insight Manager on ProLiant servers. NOTE: Some operating systems may not support all of these features.
Integrated Configuration and Management Tools – The Modular Smart Array 20 utilizes the standard, integrated set of Smart Array management and utility software. These tools consistently lower the cost of ownership by reducing training and technical expertise necessary to install and maintain HP server storage.
