Overview
The IBM x3400 server has been revised over three different generations (M1-M3). The best way to determine which server you have is via the 4-digit IBM feature code on the front of your server. Certain upgrade options are common across all three generations (such as disk drives), but other features such as CPU upgrades are not common across all generations.
All x3400 servers have optional internal (non-RAID) SATA disk modules. Contact us if you need an internal disk drive replacement.
| FC | Max Memory | Max # CPUs & Speed | Storage Bays (Front) |
| 7973-7976 (M1) | 32GB (8x 4GB PC2-5300) FBDIMM |
2x 2.0GHz Quad Core Xeon | 4/8x Simple-Swap SATA (1TB) 4/8x Hot-Swap SATA (1TB) 4/8x Hot-Swap SAS (600GB) *Standard models ship with 4 bays. An optional back plane upgrade allows for 8 drives. |
| 7836-7837 (M2) | 96GB (6x 8GB PC3-10600 Registered PER CPU) |
2x 2.26GHz Quad Core Xeon | 4x Simple-Swap SATA LFF (1TB) 4x Hot-Swap SATA LFF (1TB) 4x Hot-Swap SAS LFF (600GB) 8x Hot-Swap SFF SAS (600GB) 8x Hot-Swap SFF SATA (1TB) |
| 7378-7379 (M3) | 128GB / 48GB PC3-10600 via 16 / 12 Slots (Buffered / Unbuffered) when (2) CPUs are in use. | 2x 2.53GHz 6-Core Xeon | 4x Simple-Swap SATA LFF(1TB) 8x Hot-Swap SATA LFF(1TB) 8x Hot-Swap SAS LFF(600GB) 16x Hot-Swap SFF SAS 16x Hot-Swap SFF SATA * |
| Notes: | *Do not mix buffered and unbuffered memory. Do not mix memory ranks. Dual rank memory is always preferred. When using a 2nd CPU, memory should be installed in its dedicated CPU banks. | *These represent the FASTEST CPU upgrade options. Contact us for other CPU upgrade options. | *The use of (8) LFF or (16) SFF drives required an optional backplane upgrade. |
