Dell Servers vs HP Servers Comparison

Dell and HP are among the most popular brands that make powerful, sturdy, and reliable servers. Both brands share almost the same popularity and offer similar features and benefits, with a few exceptions specific to each brand. People and businesses often compare the two to pick the right one for their requirements. The choices are mostly guided by personal experiences. We look at both brands here in terms of the features and benefits they offer.

Dell Servers

Dell EMC server portfolio includes their famous PowerEdge (PE) server product line. They have introduced diverse types of PE servers over the years. They offer a broad array of product and family codes under the PE brand name. All Dell servers within a generation come with consistent chipsets in spite of different packaging. This allows them to have common system images and a set of drivers for all servers.

Types Of Dell Server

Dell PE server systems come in three form factors:

Dell also offers Specialty servers, Industrial-Grade servers, and Management solutions.

After Dell introduced Gen 10 servers in 2007, they started using a uniform naming method for their servers. The name of every Dell server has a letter that means the type of server, R (rack), T (tower), and M (modular). The letter is followed by three digits, the first of which represents the number of sockets, the second digit indicates the generation, and the last one refers to the brand of the CPU.


Apart from the standard benefits that all major brands of servers offer, the latest (12th Generation) Dell PE servers are built to provide an extra edge with the following advantages.

Processors Supported

Dell servers support multiple series and generations of different brands of Intel processors (Celeron, Pentium, Xeon, Xeon Scalable). They also support AMD Opteron and AMD EPYC processors. These advanced processors help Dell servers in delivering high performance and faster outcomes.

Raid Cards Supported

Redundant Array of Independent Disks (RAID), the data storage virtualization technology, brings together multiple physical drive components into a single unit for better performance and data redundancy. Dell servers use their own series of disk array controllers called PowerEdge RAID Controller (PERC), built for their PE servers. They come in series 5 to 11 families and support the different levels of RAID – RAID 0, RAID 1, RAID 5, RAID 10, RAID 50, and RAID 60, in both external and internal forms. PERC are enterprise-class controllers designed for fault tolerance, improved performance, better reliability, and easy management, giving the Dell servers a robust infrastructure and maximized uptime. They support SATA and SAS HDDs and SSDs.


The Dell PE servers support multiple operating systems (OS) that include BIOS, Ubuntu, and different versions of the brands – Red Hat Enterprise Linux, VMware ESXi, Windows Server, Citrix XenServer, and SUSE Linux ES. They may not support a specific OS due to its non-availability with some products, compatibility issues, or if the software vendor has discontinued the support for it.


Dell PE servers offer multiple drive form options for a variety of storage capacities. Their different models can support up to 32 2.5″ SAS/SATA HDDs or SSDs to provide max internal storage of 122 TB.

HPE’s Apollo, Superdome, and the latest servers from the ProLiant line assure reliability. However, faults have been found within the HPE servers. During a survey done in the middle of the year 2017, it came to the fore that HPE ProLiant servers had about 2.5 times more downtime than the Dell PowerEdge servers. So, on the dependability front, Dell seems to be a winner. But HPE does an impressive job with their prognostic alerts about the parts that might fail. This gives the businesses a chance to repair or replace those parts before they break down completely and become the cause for downtime.

Processors Supported

The HPE ProLiant servers from Modular, Density, Scalable, and MicroServer lines support different generations and series of Intel Celeron, Intel Core, Intel Pentium, Intel Xeon, AMD Opteron, and AMD Turion processors. These power-packed processors help the servers achieve powerful processing.

Raid Cards Supported

HP was the first organization to introduce RAID subsystems in the network servers in 1989 (HP was Compaq then). In present times, RAID technology is considered a standard and is used for most of the network data storage online. HP offers its own range of Smart Array controllers that support RAID levels 0, 1, 1+0, 5, 6, 50, and 60. They have been providing SAS-based and PCIe 2.0-compliant Smart Array controllers since 2009. Some server models of their specific lines also offer embedded HP Smart Array technology. Both Gen 8 and the newer Smart Array generation by HP come with provisions for external, internal, and embedded controllers.


HPE ProLiant servers support Microsoft, SUSE, Red Hat, Canonical, and Oracle OS. HPE also enables community Linux distributions. You can buy your complete operating environment from them.

What Is The Main Difference Between HP And Dell?

Both Dell and HPE are very similar organizations that offer comparable features in their servers, nothing major stands out as a distinction. Which brand you choose for your business will depend on your needs. However, certain performance differences were established between the two in some areas. If you compare identical server units, Dell could complete a workload like TPC-H much quicker than its HP counterpart. HP fell behind Dell 20% low in efficiency on reading performance. If both are compared for variety, HPE fares better, it offers more simplified storage equipment and switches. It has a larger segment of equipment designed for small to mid-sized businesses.

HP Price Vs. Dell Price

When you compare the cost of initial investment for both brands, HPE is more flexible in price negotiation. If you have a good relationship with your vendor and frequently order large quantities, you can get good deals. Dell’s flexibility in this area is almost nil.

However, Dell equipment is used widely; it ships its hardware assembled and tested. This saves time and a bit of cost, but their deliveries may take up to two weeks. HPE ships its servers mostly unassembled and within one to two days, but you need to get it assembled and tested from your IT provider. That involves additional cost. So, the prices of both get balanced there.


Both Dell and HPE have their own server management and monitoring technologies in place for easy maintenance of their servers, locally as well as remotely. Integrated Lights Out (iLO) is HPE’s Management tool, and Integrated Dell Remote Access Controller (iDRAC) is Dell EMC’s. Both the systems have developed over time and provide some similar features like HTML5 support. However, both are different too, in certain features.

  • iDRAC has evolved for the better in its recent generations. Use of Java is no longer required after iDRAC 7, though its Graphic User Interface (GUI) is not as good as the new iLO GUI.
  • For iDRAC, you need a physical license that you can buy in the secondary market. iLO standard version is included, but the advanced version requires a license. You cannot buy it from the secondary market. So, that locks you in with the OEM after your server’s end of life.
  • With iDRAC, updates take a slightly longer time, and overall, it is a bit slower than iLO.

When you set out to buy new servers for your business, comparisons between Dell and HPE will always be there. However, you need to assess your requirements first and gauge which brand serves your needs in the best possible way. Both these brands offer excellent options at competitive prices. Connect with your IT provider and do a logical assessment to select the brand that suits your company the best.
