- The introduction of the HP StorageWorks 8Gb PCIe Fiber Channel Host Bus Adapters brings datacenter infrastructure components to a higher level of performance and efficiency. The HP StorageWorks 8Gb PCIe FC Host Bus Adapters are priced only slightly higher than an equivalent 4Gb HBA, yet, they have the ability to deliver twice the I/O performance. In addition, an 8Gb FC HBA purchased today is backward compatible with 4Gb and 2Gb and will protect your investment longer than if you were to purchase an equivalent 4Gb HBA. If you are using storage intensive applications, such as backup / restore, database transactions, and rich media, the increased performance of the 8Gb infrastructure allows you to store and retrieve critical information faster. .
