File Server Selection Recommendations
Key Selection Criteria
When choosing a server for file storage, you need to consider several important factors that will determine the effectiveness and lifespan of your solution. The first and main criterion is the volume of stored data. Calculate the current volume of corporate files and add 50-100% for future growth over 3-5 years. Don't forget to account for space for backups if they will be stored on the same server.
The second important parameter is the number of concurrent users. For 20-50 users, a single-processor solution with basic specifications is sufficient; for 50-150 users, a dual-processor system with adequate RAM (minimum 32-64 GB) is required; and for 150+ users, powerful servers with latest-generation processors and large memory volumes (128-256 GB and more) are needed.
The third criterion is the type of stored data and performance requirements. If the main task is storing office application documents, an HDD configuration in RAID 5 or RAID 6 is sufficient. For working with databases, virtual machines, or many small files, SSDs or a hybrid configuration are required. For media production with high-resolution video, NVMe SSD arrays with maximum throughput are necessary.
Recommendations for Different Scenarios
Small Business (up to 30 users, up to 20 TB data): The optimal choice would be DELL PowerEdge T550 in basic configuration with one processor, 32 GB memory, and 4-6 x 3.5" drives with 4-8 TB capacity each in RAID 5. This configuration will provide sufficient performance, reliability, and ease of maintenance at minimal initial costs.
Medium Business (30-100 users, 20-80 TB data): DELL PowerEdge R550 with two processors, 64-128 GB memory, and 8 x 3.5" drives with 8-12 TB capacity in RAID 6 is recommended. Adding a PERC H745 RAID controller with cache memory will significantly increase performance. Such a system will handle intensive loads and provide power reserve for growth.
Large Business (100-300 users, 80-200 TB data): The ideal solution would be DELL PowerEdge R750xs or HPE ProLiant DL380 Gen11 with two powerful processors, 256 GB memory, and hybrid storage configuration: 2-4 SSDs for hot data and 8-12 high-capacity HDDs for primary storage. Advanced RAID controllers with large cache volumes are mandatory.
Enterprise Level (300+ users, 200+ TB data): For such requirements, HPE ProLiant DL380 Gen11 or ML350 Gen11 with maximum specifications is necessary: two Intel Xeon Scalable 5th generation processors, 512 GB - 1 TB memory, multi-tier storage with NVMe SSDs for critical data, SSDs for active files, and HDDs for archives. Implementation of monitoring systems, automated backup, and data replication is required.
Media Production and Video Work: The specifics of working with large video files require maximum disk subsystem throughput. Best choice — HPE ProLiant DL380 Gen11 or DELL PowerEdge R750xs with NVMe SSD array in RAID 10 for working projects and a separate high-capacity HDD array for archival storage. Installation of 10 GbE or higher network adapters is critically important to ensure sufficient network bandwidth.
Important Additional Aspects
RAID Arrays: Data protection is critically important for a file server. RAID 5 is suitable for systems with low write loads; RAID 6 provides better protection against two simultaneous disk failures; RAID 10 delivers maximum performance with adequate reliability but at 50% redundancy cost. For particularly critical systems, RAID 60 (combination of RAID 6 and RAID 0) is recommended.
Network Infrastructure: The most powerful file server won't realize its potential without appropriate network infrastructure. For offices up to 50 people, standard 1 GbE adapters are sufficient; for 50-150 users, aggregation of two 1 GbE or installation of 10 GbE adapters is recommended; for large systems, 10/25 GbE or even 40/100 GbE adapters are necessary.
Backup: The file server must be integrated into a backup system. Plan additional equipment for storing backups — either a separate NAS/SAN device, an additional server, or cloud storage. Remember the 3-2-1 rule: three data copies, on two different media, one copy offsite.
Scalability: When choosing a server, consider future expansion possibilities. Ensure there are free memory slots, space for additional drives, available PCIe slots for network adapters or RAID controllers. Also pay attention to the maximum supported configuration — sometimes it's more profitable to take a more powerful model with basic configuration and expand it as you grow than to replace the server in a couple of years.
