Tech Tip: Difference between HP BL, ML, and DL servers

Each type of server has its pros and cons. Each server type has their own unique niche and service different needs. When deciding on the type of server that’s right for you, one has to consider cost, space, cabling, management, maintenance.

HP Proliant DL Servers

HP Density Line (DL) are rack severs. They come in sizes such as the 1U rack, 2U rack, and 4U rack.

The slimmer rack servers, such as the 1U server, has a poorer performance and scalability compared to wider counterparts such as the 4U. The trade-off is between size and performance.

Because they are designed to fit as many servers into the smallest space as densely as possible, they are perfect for data centers. It’s the best way to maximize storage and/or computation.

The most popular of the HP DL servers is the HPE ProLiant DL380 server.

DL servers tend to be more expensive than their ML counterparts due to their smaller form factor. Most people find DL servers easier to work on.

If you have a rack available, then this is the one for you.

HP Proliant ML Servers

Maximized Line (ML) servers are tower servers. They tend to have lower specs as they are designed to be Small Office Home Office servers (SOHO) servers. Technically they can also be used with rails. These servers are usually bigger and take up more space than DL servers due to their support of more expansion cards.

These tower servers are designed for small and remote office environments, not data centers. Due to their large size they offer the most flexibility in terms of components and expansions that can be installed inside. ML towers are geared to small business and tend to be more affordable than DL servers. If you do not have a rack and are on a small budget, this is the one to go with.

HP Proliant BL Servers

HP Blade (BL) servers work with each other within the same chassis. Generally, softwares are used to aggregate BL servers into a clusters. Each blade in the cluster is hot-swappable, and can easily be replaced when one goes down.

Blade servers save the most space from all three types of servers. They are also the least messy since they do not require the same level of cabling that DL servers need.

This is the blade system. Blade servers are geared for data centers that use external storage.
