• SAS Cables

Enclosure port detail

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-8674 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.

Typical convention leverages the ports as follows:

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

Note: Any port can be an "upstream" or "downstream" port

The following also apply when considering daisy chaining:

• Up to three Lenovo ThinkSystem D4390 can be daisy-chained with support for up to 1 host server attached to the chain.
• For the maximum quantity of daisy-chaining D4390 per adapter, please go to the SAS RAID Controllers and HBAs section.
• Without daisy-chaining, a standalone Lenovo ThinkSystem D4390 can support up to four directly attached host servers with zoning function enabled.
• When daisy-chaining with 24Gb 450W-16e SAS HBA, please make sure you use the 24Gb SAS cables to connect to 450W-16e adapter as well as in-between D4390 enclosures for the maximum performance and interoperability.
• There is no support for intermixing chaining with D1212/D1224/D3284.

Connectivity topologies

The following figures illustrate different host connectivity topologies.

Figure 4. Connectivity topology one host with one RAID adapter and 1xD4390

Figure 5. Connectivity topology one host with one HBA adapter and 3xD4390

SAS Zoning

The SAS zoning function of D4390 allows multiple host servers to access the JBOD enclosure at the same time independently. If the zoning function is disabled (zone mode 0), the attached host server can access all the drives in the enclosure. If the zoning function is enabled (zone mode 1 or 2 or 3), each connected host server has exclusive access to a predefined set of drives in the same enclosure through different SAS ports on the ESM module. Different zone modes will have different drive partitions in association to the SAS ports on the ESM module. With zone mode set to 1, there are two equal size zones. With zone mode set to 2, there are three equal size zones. With zone mode set to 3, there are four zones (22/23/22/23). The following table shows all supported zone configurations.

• With zone mode enabled, daisy-chaining D4390 is not supported. Therefore, there is no downstream expansion port. It’s always a single, standalone D4390 enclosure when its zone mode is enabled.

The following table lists the supported zoning configurations

* Zone mode 0/1/2/3 are the value you use to enable/disable the zoning function using Lenstor utility. In zone mode 2, SAS port D on the ESM module will be disabled.
** If the hosts are running an OS/Application that supports SCSI reservations, for example a parallel distributed file system, more than 1 host attachment could be supported, but that is beyond the ability of the enclosure to enforce in zone mode 0.

The following figures illustrate different zone modes:

Zone mode 1

Figure 6. Zone mode 1 for D4390 enclosure

Zone mode 2

Figure 7. Zone mode 2 for D4390 enclosure

Zone mode 3

Figure 8. Zone mode 3 for D4390 enclosure

With zone mode 3, a single D4390 JBOD enclosure can support up to four individual host servers with the following cabling configuration as an example. Each host server can use either a SAS HBA (non-RAID) or a RAID adapter.

The following is connectivity topology of four host servers attached to one D4390 JBOD enclosure

Figure 9. Four host servers attached to one D4390 JBOD enclosure

SAS Cables

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

Note: For end-to-end 24Gb connectivity you will need 24Gb SAS adapter and 24Gb cable to connect to D4390

Configuration notes:

• Y-cables are not supported.
• For host server with CMA function, it requires another 1 meter distance to travel for the server CMA installation. The 2 meter SAS cable may not be long enough for this purpose. Plan accordingly.

The D4390 Direct Attached Storage Enclosure 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:

• The minimum of 15 drives have to be inserted in row 1. This is highly suggested to be followed even in configurations with zone mode other than 0 applied.
• For HDDs, add drives (a complete 15 drives per row is highly recommended) starting from the front row of the system (row1) and moving towards the rear row (next to the fan modules, row 6).For configurations with zone mode other than 0 applied, install drives at the start of the zone and install in ascending order.
• A partial filled row of drives (less than 15) is allowed, but if additional drives are added later, the row must be filled completely firstly before adding more drives to the next empty row.For configurations with zone mode other than 0 applied, install drives in ascending order according to the zone of drives.
• While SSDs are supported in any of the 90 drive slots, for lowest possible latency on the SSD drives it is recommended to use slot 1 to slot 12 on row 1.
• Intermixing HDDs of various sizes within a row is supported.

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

The Lenovo ThinkSystem D4390 Direct Attached Storage Enclosure supports up to four redundant hot-swap power supplies. In the Lenovo configurators power supplies are automatically derived and not individually configurable.

​​​​​

• The D4390 Titanium 1300W AC-DC CSRP power supply operates at both 230V and 110V.
• The D4390 Titanium 1300W AC-DC CSRP power supply supports AutoSensing of the input power.
• At 230V the power supplies are N+N (N=2), 2+2. If 1 or 2 PSUs fail. Unit can operate with as few 2 PSUs.
• At 110V the power supplies are N+1 (N=3), 3+1. If 1 PSU fails. Unit operates at 3 PSUs.

Power cords

• Line cords and rack power cables with C13 connectors can be ordered as listed in the following table.

* Four cables are needed with the D4390 models listed in the Models section.

Due to the absence of a web interface for enclosure management and the inactivation of the RJ45 port, all enclosure management functions and services must be conducted through in-band SAS commands. To facilitate this process, Lenovo offers the Lenstor utility, which aids customers in firmware updates, log collection, overall status assessment, and all other enclosure management tasks.

The Lenstor utility is a binary executable file compatible with Linux-based operating systems, such as RedHat and SLES as well as Windows Server operating systems. Please note that this utility is exclusively designed for the ThinkSystem D4390 enclosure, allowing hosts with either non-RAID or RAID adapters installed and connected to the D4390 to interact with the enclosure(s).

Before updating the firmware, it is a good practice to back up the user data, and configuration of RAID adapter. With zoning function enabled, it is highly recommended to stop all I/O between host server and the drives in ThinkSystem D4390 enclosure before performing the firmware update.

To download the Lenstor utility, please visit the Lenovo Data Center Support page. Additionally, we recommend reviewing the accompanying readme file within the Lenstor utility software package for further information under Drivers & Software from same support page noted above.

The ThinkSystem D4390 is a Direct Attached Storage (DAS) enclosure that does not feature Ethernet capabilities or a web management interface. Its serial COM port is secured by a user-defined password. Provided that the host server to which the ThinkSystem D4390 is connected is secure and well-protected, the enclosure remains free from security vulnerabilities.

A fully assembled D4390 enclosure can weigh up to 100kg. To ensure a safe and efficient installation experience, the following guidelines should be observed:

• Stability is maintained by starting the installation of enclosures at the bottom of the rack.
• Rack cabinet balance can be enhanced by securing it to the floor using stabilizers.
• When installing multiple D4390 enclosures in a single rack, it is recommended to begin from the bottom and work upwards.
• To prevent a rack from tipping over while servicing drives in a rack with multiple D4390 enclosures, only one enclosure should be pulled out at a time, and pulling out multiple enclosures simultaneously should be avoided.

The D4390 system base includes the necessary railkits for seamless rack installation. Detailed railkit installation instructions can be found in the D4390 Hardware Installation and Maintenance Guide. For a quick reference, the Getting Started Guide poster, provided with the system base package, can also be consulted.

• Device as a Service (DaaS)

  Leverage latest technology to advance your business. Customized solutions aligned to your needs. Flexibility to add equipment to support growth. Protect your technology with Lenovo's Premier Support service.

• 24/7 Asset management

  Manage your financed solutions with electronic access to your lease documents, payment histories, invoices and asset information.

• Fair Market Value (FMV) and $1 Purchase Option Leases

  Maximize your purchasing power with our lowest cost option. An FMV lease offers lower monthly payments than loans or lease-to-own financing. Think of an FMV lease as a rental. You have the flexibility at the end of the lease term to return the equipment, continue leasing it, or purchase it for the fair market value. In a $1 Out Purchase Option lease, you own the equipment. It is a good option when you are confident you will use the equipment for an extended period beyond the finance term. Both lease types have merits depending on your needs. We can help you determine which option will best meet your technological and budgetary goals.
