This JBOD supports 24Gb SAS and providing performances. High density and performance make it for workloads such as virtualization, enterprise backup storage, cold and warm data storage.
The J4078-02-04X is a 4U top-loading JBOD that supports 78 units of 3.5″ enterprise capacity HDDs, up to 1.PB+ of storage. On-boarded with the Broadcom 24Gb SAS expanders on hub expander modules, the J4078-02-04X I/O performance improves 100% compared to its previous generation. While J4078-02-04X edge expanders remain at 12Gb SAS, it is proven that the doubled bandwidth on hub expanders is the key of enhanced I/O performances.
This directly addresses the performance demand of high density storage in the market while most of the other 4U top-loading JBODs are using 12Gb SAS hub expanders with limited bandwidth for data transmission. Its dual hub expander modules support dual-path redundancy for host link and expansion link. Designed with HA and balanced architecture, each hub expander has 4 MiniSAS HD, providing a total of 16 ports and supporting up to 384Gb/s. With 810mm in depth, J4078-02-04X is one of the shortest in its category and can fit into any existing one meter rack. Its modularized enclosure is designed with hot-swap components and redundant features to increase reliability and ease of maintenance.
The Broadcom 24G SAS expander boosts the doubled I/O performances of J4078-02-04X. It is compliant SAS-4 SerDes. By maximizing the available throughput to the host, the SAS4x expander couples next gen SAS-4 technology and provides high device throughput with SAS to support up to 22.5Gb /s, doubling the effective bandwidth over prior 12Gb/s expanders without compromising energy efficiency and package size. From software and firmware perspectives, the Broadcom 24G SAS expander SDK has 95% commonality with legacy Broadcom SAS expanders, supporting AIC to reduce the resources for developing J4078-02-04X.
“Market demands of 4U top-loading JBOD are soaring as it is cost-effective and can support enterprises to minimize the cost per gigabyte,” said Michael Liang, CEO and president. “I am honored to collaborate with Broadcom in developing J4078-02-04X which is one of the first-to-market SAS4x ready 4U top-loading JBODs. With the aid from Broadcom SAS4x expanders, J4078-02-04X will support our customers to run the most data-intensive storage applications.“
“The strong collaboration between Broadcom and AIC continues with the SAS4x expander family and the J4078-02-04X technology alignment,” said, Zee Shirazi, global head, marketing, data center solutions group, Broadcom, Inc. “Data-centric applications require servers with high I/O performance to move, process, and store massive amounts of data. With AIC’s deep expertise in high-density storage, the J4078-02-04X utilizes the full capability of the Broadcom SAS4x expander family and takes performance to the next level. I am certain this JBOD will support our customers as they tackle the challenges found in today’s high density, demanding storage workloads.”
J4078-02-04X samples will be ready in 3Q22.
