Frequently Asked Questions
What does the Intel Silver 4110 processor mean for this server's workload capacity?
The Xeon Silver 4110 is an 8-core/16-thread Skylake-SP chip running at 2.1GHz base with 11MB L3 cache and a 85W TDP. It handles moderate-to-heavy virtualization, database, and web workloads efficiently — you're not getting the core density of a Gold or Platinum SKU, but for SMB or departmental deployments it's more than adequate.
Is 16GB of RAM enough for production use, and can it be expanded?
16GB is a starting point, not a ceiling. The R640 supports up to 24 DIMM slots depending on configuration and can scale to 3TB of DDR4 RAM. For most virtualization stacks running 4–8 VMs, 64–128GB is a more practical target — plan to add DIMMs before deploying in a demanding environment.
What RAID levels does the H730 controller support, and how does it protect the eight 300GB drives?
The PERC H730 supports RAID 0, 1, 5, 6, 10, 50, and 60 with a 1GB non-volatile cache backed by a battery or flash module. Across eight 300GB 15K SAS drives, RAID 6 gives you fault tolerance against two simultaneous drive failures while still delivering strong sequential throughput — appropriate for workloads where data integrity outweighs raw capacity.
What does "8x2.5 Hot Plug" mean in practice?
It means the server ships in the 2.5-inch small-form-factor bay configuration with all eight drive sleds accessible from the front without powering down. Hot-plug is critical in production: you can swap a failed drive mid-operation and let the RAID controller rebuild without scheduling downtime.
Does this renewed unit include rail kits or a warranty?
Renewed units typically do not include rail kits — verify with the seller before purchasing if rack mounting is required. Warranty coverage varies by seller; Dell's original hardware warranty on renewed units should be confirmed at time of purchase.
