The Lenovo ThinkSystem D4390 supports 24 Gbps SAS connectivity, which doubles the data transfer rate compared to 12 Gbps SAS solutions to maximize performance of storage I/O-intensive applications.

With support for daisy chaining, the D4390 can be scaled up to 3.240 PB for capacity-optimized configurations.

The Lenovo ThinkSystem D4390 Direct Attached Storage is a single, flexible expansion platform that utilizes existing infrastructure, providing a lower TCO and immediate savings on traditional capital costs.

Key features and benefits provided by theD4390 Direct Attached Storage include:

• Versatile, scalable storage expansion with dual Electronic Service Module (ESM) configurations for high availability and performance
• Flexible host connectivity to match diverse client needs for direct attach storage with support for 12 Gb or 24 Gb SAS RAID adapters for advanced data protection or 12 Gb or 24 Gb SAS Host Bus Adapters (HBAs) for maximum JBOD performance
• Support 90x 3.5-inch large form factor (LFF) 12Gb Nearline SAS drives in a 4U rack space
• Scalability of up to 180 drives per HBA with the attachment of up to two D4390 daisy-chained high density expansion enclosures
• Flexibility in storing data on high performance SAS SSDs or capacity-optimized enterprise NL SAS HDDs; mixing and matching drive types on a single HBA to perfectly meet performance and capacity requirements for various workloads
• Support multiple host attachments

The D4390 Direct Attached Storage is designed to support a wide range of data storage requirements, from highly utilized applications to high-capacity, low usage applications.

The following SAS drives are supported by the D4390:

• High-capacity, archival-class nearline HDDs, up to 18 TB 7.2K rpm
• High performance SSDs (2.5" drive in 3.5" tray): 800 GB

Additional drives and expansion units are designed to be dynamically added with virtually no downtime (operating system dependent), helping to quickly and seamlessly respond to growing capacity demands.

The D4390 Direct Attached Storage is designed to offer high levels of system and data availability with the following technologies:

• Dual ESMs provide redundant paths from a supported HBA to the drives in the enclosures for I/O load balancing and failover
• Dual-port drives (both HDDs and SSDs)
• Redundant hardware, including host ports, ESMs, power supplies, 5V DC/DC regulators and cooling fans
• Hot-swappable and customer replaceable components; including ESMs, power supplies, cooling fans, 5V DC/DC modules, and drives

The following figures show the front of the D4390 Direct Attached Storage.

Notes:

• The ESMs (shown in the previous figure) have additional service ports, and these ports are reserved for use by a Lenovo service technician.
• The Ethernet management port on the ESMs are disabled.

The following table lists the D4390 system specifications.

The following table lists the relationship models of the D4390 drive enclosures.

The D4390 high density expansion enclosure supports dual electronic service module (ESM) configurations. Each ESM has four universal 12/24 Gb SAS x4 ports (Mini-SAS HD SFF-8644 connectors). These ports are used for connections to a supported SAS RAID controller or SAS HBA installed in a server and for daisy chaining the D4390 enclosures between each other.

Cabling is as follows:

• A, B, C ports are for upstream
• D ports is for downstream

Up to two Lenovo ThinkSystem D4390 can be daisy-chained with support for up to 1 host server attached to the chain.

Without daisy-chaining, a standalone Lenovo ThinkSystem D4390 can support up to 1 directly attached host server.

• There is no support for intermixing chaining with D1212/1224/3284.

The following table lists ordering information for the SAS cables that are supported with the D4390.

Configuration notes:

• Y-cable is not supported.

The D4390 Direct Attached Storage supports up to 90x 3.5-inch hot-swap drives. The supported drive types are NL SAS HDDs and SAS SSDs.

The following rules apply when adding drives to a system that start with less than 90 drives, add them in the following manner :

• For HDDs, add only complete rows of 15 drives at a time starting from the back of the system (the row next to the fan modules, row 6) and moving towards the front (row1).
• A partial filled row (except the back row, row 6) of drives (less than 15) is allowed, but if additional drives are added later, the row must be filled completely before adding more drives to the next empty row.
• For SSDs, drive slot 1 ~ slot 12 on row 1 is recommended for SSD usage for low latency. SSDs are allowed on drive slot 1~90 just like HDDs.
• HDDs and SSDs can be mixed and coexist on any row in the enclosure.
• Intermixing HDDs of various sizes within a row is supported.

The following tables list drive options for the D4390 Direct Attached Storage.

Some regions might have different warranty terms and conditions than the standard warranty. This is due to local business practices or laws in the specific region. Local service teams can assist in explaining region-specific terms when needed. Examples of region-specific warranty terms are second or longer business day parts delivery or parts-only base warranty.

If warranty terms and conditions include onsite labor for repair or replacement of parts, Lenovo will dispatch a service technician to the customer site to perform the replacement. Onsite labor under base warranty is limited to labor for replacement of parts that have been determined to be field-replaceable units (FRUs). Parts that are determined to be customer-replaceable units (CRUs) do not include onsite labor under base warranty.

If warranty terms include parts-only base warranty, Lenovo is responsible for delivering only replacement parts that are under base warranty (including FRUs) that will be sent to a requested location for self-service. Parts-only service does not include a service technician being dispatched onsite. Parts must be changed at customer’s own cost and labor and defective parts must be returned following the instructions supplied with the spare parts.
