What is the 82885T Microsemi Adaptec SAS Expander card?
The Microsemi Adaptec 82885T is the industry’s first 36 port, 12 Gbps SAS expander card in a low profile PCIe form factor. It allows you to connect more SAS & SATA devices such as hard disk drives and SSDs to a single controller because it enables you to fan-out from a single connection to multiple connections.
How are the ports configured on the card?
The 82885T has 8 external ports for external storage expansion, 28 internal ports. 24 internal ports can be directly attached to drives and the other 4 or 8 internal ports are for connectivity to the SAS RAID adapter or SAS HBA.
What are the performance benefits?
The Microsemi Adaptec SAS expander card features SAS and SATA edge buffering capabilities that enable it to increase total throughput to the controller even when using 6 Gbps SAS drives. This is achieved by bursting data at 12 Gbps when connected to 6 Gbps SAS or SATA devices when utilized in conjunction with a 12 Gbps capable adapter such as the Microsemi Adaptec Series 8 SAS RAID or SAS HBAs.
Does the expander card need a driver?
The 82885T is used as a companion card with a RAID adapter or HBA. The card presents itself as an internal SES device to the RAID adapter or HBA so no unique driver is required for the expander card.
How compatible is the 82885T expander card?
The 82885T is compatible with all Microsemi Adaptec Series 8, Series 7 and Series 6 RAID adapters and HBAs and have been tested and supported with 3rd party RAID adapters, HBAs, all HDDs and SSDs, and existing active and passive backplanes. Please visit our website at www.adaptec.com/compatibility for a list of tested components.
What management utilities are included with the 82885T?
Microsemi Adaptec maxView Storage Manager is a one-view utility which centralizes management and will display the drives behind the 82885T. maxView can be downloaded from www.adaptec.com/en-us/support.
Each card is backed by a 3-year warranty and Microsemi Adaptec industry-leading technical support.
What applications is the expander card ideal for and why?
The 82885T SAS expander card is an ideal low cost, fan-out solution for high density storage server applications while enabling a passive backplane architecture in the server. The 82885T also provides for optional connectivity to external JBODs for even greater capacity expansion on a single SAS RAID adapter or HBA.
Market Dynamics
What applications being targeted for the SAS Expander Card?
Ideal for density optimized servers requiring direct connectivity to 24 SAS or SATA HDDs or SSDs. The 82885T simplifies cabling and eliminates the need for costly external enclosures by mounting internally to any available PCIe slot, away from the backplane and offers significantly lower power consumption than competing solutions.
