The HP StorageWorks 1500cs Modular Smart Array (MSA1500) is a Fiber Channel storage area network (SAN) 2U controller shelf that connects to HP StorageWorks Serial ATA (SATA) and/or SCSI disk enclosures. Together they provide customers with a flexible low-cost, high capacity storage solution. The MSA1500cs has been designed as a hardware foundation for future solutions to ensure maximum investment protection. New alternative firmware gives active/active functionality to HP-UX, Windows and Linux, giving even higher performance then before.The MSA1500cs is perfect for those customers looking for less expensive storage solutions using HP SATA enclosures to store data that doesn't require a high degree of I/O performance and/or is viewed as non-mission critical to business operations. The MSA1500cs with up-to-eight attached SATA enclosures can provide the customer with up to 48 TB (96 - 500 GB SATA disk drives) of native capacity. If the business requires enterprise-class SCSI reliability then attach up-to-four SCSI enclosures for a native capacity of 16.8 TB (using 56 - 300 GB SCSI disks).By using existing SCSI drive enclosures, MSA1000 controller technology, and integrating low cost SATA hard drives and enclosures, the MSA1500cs lowers the total cost of ownership and protects the customer's hardware investments.
