Power supply features- IBM Power E1050

The Power E1050 server has four AC to DC 2300 W Titanium classed power supply units (PSUs). The PSUs are concurrently maintainable.

Note: A Titanium-certified (best in class) power supply has an efficiency of 90% – 95% on load.

Every 1% efficiency loss at the PSU requires more than 1% more power to accomplish the same output. Efficient power supplies help data centers to achieve their sustainability goals.

The Power E1050 power supplies have 2+2 redundancy. The failed PSU is hot-pluggable.
Ê When one PSU is defective during run time, the system continues to run with full performance.
Ê When two PSUs are defective during run time, the system continues to run, but might throttle as needed.
Ê During boot, the system requires three PSUs to be installed, but will power on with only two good PSUs.

3.4 Peripheral Component Interconnect adapters

This section covers the various types and functions of the PCIe adapters that are supported by the Power E1050 (9043-MRX). This list is based on the PCIe adapters that are available on the GA date of these systems, but it is subject to change as more PCIe adapters are tested and certified, or listed adapters are no longer available. The latest list of supported adapters is available at the Announcement Letter or Sales Manual page, which can be found at the IBM Offering Information website.

The following sections describe the supported adapters and provide tables of orderable and supported feature numbers. The tables indicate OS support (AIX and Linux) for each of the adapters.

Note: The maximum number of adapters in each case might require the server to have an external PCIe expansion drawer.

The Order type table column in the following subsections is defined as follows:

Initial Denotes the orderability of a feature only with the purchase of a new system.

MES Denotes the orderability of a feature only as part of an MES upgrade purchase for an existing system.

Both Denotes the orderability of a feature as part of both new and MES upgrade purchases.

Supported Denotes that feature is not orderable with a system, but is supported; that is, the feature can be migrated from existing systems, but cannot be ordered new.


3.4.1 Local area network adapters

To connect the IBM Power E1050 server models to a local area network (LAN), you can use the LAN adapters that are supported in the PCIe slots of the system. Several connection speeds and physical connections are supported.

Table 3-6 lists the LAN adapters that are supported within the Power E1050 servers.

Table 3-6 LAN adapters for the Power E1050 server

a. Requires one or two appropriate transceivers to provide 10 Gbps SFP+ (#EB46), 25 Gbps SFP28 (#EB47), or 1 Gbps RJ45 (#EB48) connectivity as required.

b. Linux support requires Red Hat Enterprise Linux (RHEL)8.4 or later, Red Hat Enterprise Linux for SAP 8.4 or later, SUSE Linux Enterprise Server 15 Service Pack 3 or later, SUSE Linux Enterprise Server for SAP with SUSE Linux Enterprise Server 15 Service Pack 3 or later, or Red Hat OpenShift Container Platform 4.9 or later. All require Mellanox OFED 5.5 drivers or later.

c. To deliver the full performance of both ports, each 100 Gbps Ethernet adapter must be connected to a PCIe slot with 16 lanes (x16) of PCIe Gen4 connectivity.

3.4.2 Fibre Channel adapters

The Power10 processor-based Enterprise Midrange servers support connection to devices that use Fibre Channel (FC) connectivity, either directly or through a storage area network (SAN). There is a range of PCIe connected FC adapters that are available in both low-profile and full-height form factors.

All supported FC adapters have LC connections. If you are attaching a switch or a device with an SC type fiber connector, then an LC-SC 50-Micron Fiber Converter Cable (#2456) or an LC-SC 62.5-Micron Fiber Converter Cable (#2459) is required.

Table 3-7 lists the FC adapters that are supported within the Power E1050 servers.
