Dell 01HGDK EMC Poweredge R740 16-Bay SFF Server Backplane Expander

The Lenovo 01KR353 is a 16GB DDR4-2933 Registered ECC Memory module (RDIMM). It is a genuine Lenovo ThinkSystem / TruDDR4 enterprise memory module, with Samsung OEM equivalent M393A2K40CB2-CVFCO.

This is a Single Rank x4 (1Rx4) 16GB DDR4 RDIMM running at 2933 MHz (PC4-23400). It is optimized for Lenovo ThinkSystem servers and provides excellent performance with lower power consumption compared to higher-rank modules. The module is fully validated by Lenovo for stability and compatibility in their latest server platforms.

The IBM 01LJ138 is the official hot-swap drive caddy (also called LFF hard drive tray, carrier, or sled) for 3.5-inch Large Form Factor (LFF) drives in the IBM Storwize V7000 Gen2 (models 2076-524/624/724) and Storwize V9000 systems (and compatible expansion enclosures).

This is a tool-less, hot-swappable drive tray designed to securely hold and mount standard 3.5-inch SAS/SATA HDDs or SSDs into the Storwize V7000 Gen2 or V9000 front drive bays. It features:

• Black plastic/metal construction with a spring-loaded latch
• ESD (electrostatic discharge) protection
• Vibration-dampening mounts to reduce drive wear in dense enclosures
• LED pass-through for drive activity/fault indicators
• Alignment pins/guides for fool-proof insertion into the backplane

The caddy is mandatory for installing or replacing drives in these systems — bare drives cannot be inserted directly. It is the exact same tray used in most IBM Storwize V7000 Gen2 and V9000 enclosures (24-bay LFF or 12-bay LFF configurations).

Failure to use the correct tray (or using a mismatched tray from V7000 Gen1, V5000, or other vendors) can cause:

• Drive not detected
• Backplane connection failure
• Vibration-induced errors
• Improper seating or ejection

This tray is a very common FRU (Field Replaceable Unit) when trays are lost, damaged, cracked, or worn out during drive replacements.

The IBM 01LJ126 is a hot-swap fan module (also listed as fan FRU or cooling module) designed specifically for the IBM Storwize V5000 Gen2 storage systems, particularly the 92F model (24-bay 2.5-inch SFF enclosure) and related expansion units in the V5000 Gen2 family.

This is a high-speed, redundant fan assembly that provides active cooling for the Storwize V5000 Gen2 controller enclosure or expansion enclosure (92F = 2.5" SFF 24-drive canister). The module contains multiple high-RPM fans arranged in a single replaceable tray, with integrated airflow direction optimized for front-to-back cooling in the enclosure.

Key characteristics:

• Hot-swappable design — can be replaced without powering down the enclosure when redundancy is maintained (N+1 fan redundancy typical in V5000 Gen2)
• Built-in fault detection and reporting to the Storwize firmware (via LED status and system alerts in GUI/CLI)
• Tool-less insertion/removal with latch mechanism
• Front-to-back airflow (cold aisle intake, hot aisle exhaust)
• Low acoustic noise profile for data center environments

Failure of a fan module typically triggers:

• Amber fault LED on the module
• Enclosure fault light
• Critical alert in Storwize GUI / CLI / email / SNMP
• Potential thermal throttling or enclosure shutdown if multiple fans fail

Replacement restores full cooling redundancy and prevents overheating of drives, controllers, or cache batteries.

The Cisco 03-25641-0600 (also known as UCSB-MRAID12G, UCS VIC 1340 + RAID controller bundle, or FlexStorage 12Gbps SAS RAID Storage Controller) is a modular RAID storage controller designed specifically for Cisco UCS B-Series Blade Servers (particularly B200 M3/M4/M5 generations) and some C-Series rack servers with modular LOM (LAN on Motherboard) and storage options.

This is not a standalone PCIe card but a mezzanine-style FlexStorage module that combines:

• Cisco VIC 1340 (Virtual Interface Card) – dual-port 10GbE + storage connectivity
• LSI SAS 3008/3108-based RAID controller – 12 Gbps SAS-3 with hardware RAID support

It installs into the dedicated mezzanine slot on UCS B200 blade servers (or equivalent C-Series modular slot), providing:

• Dual-port 10GbE networking (via VIC 1340) for high-bandwidth fabric interconnect
• 12 Gbps SAS RAID with up to 8 internal SAS/SATA drive ports (supports RAID 0/1/5/6/10/50/60)
• Integrated supercapacitor cache (no battery) for write-back caching during power loss
• Full Cisco UCS integration with UCS Manager (service profiles, firmware updates, monitoring)

The controller supports MegaRAID firmware from Broadcom/LSI, with Dell EMC UCS branding and validation for seamless UCS blade operation. It was a very common configuration in UCS B200 M4/M5 blades for servers needing both high-speed networking and hardware RAID for internal drives without using a full PCIe slot.

The Dell 02TRM4 is an enterprise-class 1.8TB SAS hard disk drive (HDD) in 2.5-inch SFF (Small Form Factor) with a 12 Gbps SAS (SAS-3) interface and 10,000 RPM spindle speed. It is an OEM-branded version of the Toshiba AL14SEB18EQ (or equivalent AL14SEB series), certified and rebranded by Dell for use in PowerEdge servers and Dell EMC storage platforms.

This is a high-performance, tier-1 enterprise SAS HDD optimized for low-latency random I/O, high IOPS, and reliable 24×7 operation in demanding workloads such as databases, virtualization, VDI, OLTP, transactional systems, boot/OS volumes, and primary storage tiers where speed and responsiveness matter more than maximum capacity per drive.

The drive features:

• Dual-port SAS for redundancy and multipathing in high-availability configurations
• 128 MB cache buffer for improved burst and sustained performance
• 512e (512-byte emulation / Advanced Format) sector format for broad OS/RAID compatibility
• Advanced rotational vibration safeguards to maintain stability in dense multi-drive enclosures

In Dell deployments, the 02TRM4 is commonly used as a performance tier drive in PowerEdge servers (especially 13G–15G generations: R630/R640/R730/R740 series) and compatible Dell EMC storage arrays. It is a popular replacement or upgrade drive for systems needing high random IOPS alongside SSD tiers for hybrid performance/cost balance.
