About Areca

Areca Technology Corp., founded in 1999, is one of the few significant RAID Adapter and SAS HBA manufacturers (real manufacturers) in the world today (excluding those Re-branded Names but OEMed from the Original Maker). The Areca engineering team has more than 30 years of experience in firmware/BIOS, software, device drivers, and ASIC technologies related to disc arrays. Areca has dedicated all of its research and development resources to developing disc array technologies that outperform competing disc array systems in terms of speed, dependability, and price.

Areca offers a full line of RAID & Storage products: from PCIe SATA RAID, SAS HBA, SAS RAID Adapters to External RAID modules, Thunderbolt, USB 3.1 Gen 2 and complete RAID Systems, even an FC Gateway / Bridge for SAN RAID connectivity; and it has the broadest OS supports: Windows, Linux, BSD/FreeBSD, XenServer, illumos, unRAID, FreeNAS, NAS4Free, Solaris 10/11, and Mac OS X 10.5.x or Higher. You can always find anything on Areca’s product list to suit your needs in terms of price, features, and performance.

Introduction

The ARC-4038 SAS-to-SAS JBOD box provides a compact external storage chassis capable of accommodating up to 8/12 12Gb/s Serial-Attached SCSI (SAS) drives or 6Gb/s Serial ATA (SATA) drives. The box can support both 3.5-inch disk drives and 2.5-inch disk drives, each one contained in its hole on the disk carrier. The expander module on ARC-4038 is designed with an integrated ARM Cortex-R4 processor for topology management functions such as discovery, enclosure and drive management, and LED management. Each ARC-4038 compact tower JBOD supports four 12Gb/s SFF-8644 and one 6Gb/s SFF-8088 SAS host and expansion connections. Out-of-band CLI can redefine the manufacturer’s default setting on those connections. Configuration and environmental information are accessible either via in-band (SES-3.0 over SMP) or out-of-band serial port.

Unparalleled Performance

The 12Gb/s ARC-4038 offers 28 ports of connectivity in an 8/12-bay desktop tower. It can provide internal connectivity for up to 8/12 direct attached SAS/SATA HDDs and or SSDs and 20 external ports (using 4 x SFF-8644 and 1 x SFF-8088 connector) for storage host/ expansion connections. High-performance architecture sets new boundaries of industry performance expectations: 12Gb/s SAS or 6.0Gb/s and 3Gb/s SAS/SATA. The ARC-4038 incorporates the latest enhancements in SAS along with new LSI DataBolt bandwidth optimizer technology. This is designed to help facilitate the industry transition to 12Gb/s SAS-enabled systems by allowing users to take advantage of 12Gb/s speeds while utilizing existing 6Gb/s drives and backplanes. Using DataBolt, the ARC-4038 buffers 6Gb/s data and then transfers it out to the host at 12Gb/s speeds to match the bandwidth between faster hosts and slower SAS or SATA devices.

Easy Management

The ARC-4038 contains an embedded expander manager that can access via in-band SES-3.0 over SMP protocol and out-of-band RS232 port. An out-of-band serial port is available for managing the configuration and monitoring the expander. The ARC-4038 expander firmware and EPLD have implemented the SES-3.0 protocol and disk activity map to the individual fault/activity status indicator on the backplanes. It has implemented autonomous chassis management of power supply status connectors, and two fan monitor/speed control connectors through the SES-3.0 protocol. In data center environments, identifying issues with drives and environments are crucial. The hardware monitor can monitor system voltage and temperature. The warning message will be shown on the alarm buzzer and respect LED.

Maximum Interoperability

Areca presents its ultra-high performance and high-reliability 12Gb/s SAS expander module for a cost-effective and enterprise-class JBOD storage enclosure. A 12Gb/s SAS expander module literally expands the number of end devices that you can connect together. Expander devices, typically embedded into an expander module to connect the system backplane, support large configurations of SAS end devices, including SAS host/RAID adapters and SAS and SATA disk drives. The SAS protocol defines a mechanism that has been implemented in the SAS expanders to guarantee fair access between drives in a domain. The ARC-4038 is ideal for 12Gb/s SAS storage systems with external interfaces and gets the benefit of more storage capacity. The type and total amount of drives you use are based on the host interface in the server that the JBOD is connected. Host-based RAID configuration is supported via an external connector on PCIe to 12Gb/s SAS RAID controller, external series SAS/Fibre/iSCSI to 12Gb/s SAS RAID and SAS host adapters.

FAQs Areca ARC-4038 8-Bay SAS Expander Tower JBOD Enclosure

What is the Areca ARC-4038 8-Bay SAS Expander Tower JBOD Enclosure?

The Areca ARC-4038 is an 8-bay SAS expander tower JBOD (Just a Bunch Of Disks) enclosure. It is a storage device that allows you to connect multiple hard drives or solid-state drives (SSDs) to a host system using SAS (Serial Attached SCSI) technology. The enclosure expands the storage capacity of the host system and provides a centralized solution for managing and accessing the connected drives.

How many drives can the Areca ARC-4038 accommodate?

The Areca ARC-4038 can accommodate up to eight drives. These can be 3.5-inch or 2.5-inch SAS or SATA (Serial ATA) drives. The enclosure supports both SAS and SATA drive interfaces, giving you flexibility in choosing the type of drives to use.

What is a SAS expander?

A SAS expander is a device that allows you to connect multiple SAS drives to a host system using fewer physical connections. It acts as a hub or switch for SAS drives, enabling you to connect more drives than the number of available ports on the host system. This helps in maximizing storage capacity and simplifying cable management.

What RAID configurations does the Areca ARC-4038 support?

The Areca ARC-4038 supports various RAID configurations, including RAID 0, RAID 1, RAID 10, RAID 3, RAID 5, RAID 6, RAID 30, RAID 50, and RAID 60. RAID (Redundant Array of Independent Disks) is a technology that allows multiple drives to be combined for improved performance, data redundancy, or both.

How do I connect the Areca ARC-4038 to a host system?

The ARC-4038 connects to a host system using SAS cables. You need a SAS HBA (Host Bus Adapter) or RAID controller in the host system that supports SAS connectivity. The SAS cables connect from the HBA or RAID controller to the SAS ports on the ARC-4038 enclosure.

Can the Areca ARC-4038 be used with both Windows and macOS?

es, the Areca ARC-4038 is compatible with both Windows and macOS. The enclosure relies on the host system’s operating system and the SAS controller drivers installed on the system. As long as your system supports SAS connectivity and you have the appropriate drivers installed, you should be able to use the ARC-4038 regardless of the operating system.

Does the Areca ARC-4038 support hot-swapping of drives?

Yes, the Areca ARC-4038 supports hot-swapping of drives. Hot-swapping allows you to remove and replace drives while the system is powered on and operating without shutting down or restarting the system. This feature makes it convenient to replace or upgrade drives without interrupting storage operations.

Can I use SSDs (Solid-State Drives) with the Areca ARC-4038?

Yes, you can use SSDs with the Areca ARC-4038. The enclosure supports both SAS and SATA drives, and SSDs are available in both SAS and SATA interfaces. SSDs offer faster data access and transfer speeds compared to traditional hard disk drives (HDDs), which can improve overall system performance.

What are the dimensions of the Areca ARC-4038 enclosure?

The exact dimensions of the Areca ARC-4038 may vary, but as a general reference, the enclosure is typically designed to fit in a standard 3.5-inch drive bay. It is usually around 5.7 inches (14.5 cm) in width, 6.5 inches (16.5 cm) in height, and 8.7 inches (22 cm) in depth. However, it’s recommended to refer to the specific product specifications or consult the manufacturer for accurate dimensions.

Does the Areca ARC-4038 support RAID expansion or migration?

Yes, the Areca ARC-4038 supports RAID expansion and migration. RAID expansion allows you to add more drives to an existing RAID array to increase its capacity. RAID migration allows you to change the RAID level of an existing array without losing data. These features provide flexibility and scalability in managing your storage configuration.
