Therefore, scalability is not a problem."

Pricing and Cost Advice
  • "Pricing will be based on your requirements so it is important to plan, engage, and negotiate directly with the Cisco Account Manager."
  • "UCS is expensive, and we will be migrating to the cheaper HP servers."
  • "Cisco UCS B-Series is an expensive solution."
  • "This is a premium device and our clients are not as concerned about the reasonableness of the price compared to satisfaction with their productivity."
  • "The licensing cost is a little bit expensive because by default, it depends on your fabric interconnect model. Most of the time, however, Cisco provides a lot of promotions to the customers, so the cost can be waived for many projects. The price of the chassis itself is fair."
  • "The cost of the blade servers is okay, but the cost of Fabric Interconnects ends up increasing the overall costs. For example, suppose it costs 3,500 USD per blade server. When you include the Fabric Interconnects, you could pay up to 30,000 USD. Therefore, compared to the cost of servers from Lenovo, Huawei, Dell, or HP, the cost of Cisco servers can be high. However, Cisco gives good discounts (about 90% to 94%) to partners and to customers who are already using Cisco servers. New Cisco customers do not get the level of discount that an existing customer does. Because you can get discounts with Cisco, I would give pricing a rating of four out of five."
  • "Cisco UCS B-Series is an expensive solution."
  • "Compared to the more in-demand hyper-converged environments such as Nutanix or DVX rail, Cisco UCS B-Series is even more costly due to the expensive fabric interconnects."
  • More Cisco UCS B-Series Pricing and Cost Advice →

  • "There is a one-off payment to buy the equipment and the support is purchased annually."
  • "The is an annual license cost to use the Lenovo Flex System. If the price was less expensive and flexible overall and for additional features, our customers would be happier."
  • "The 14 blade server allows significant room for upscaling before having to invest in another chassis. You would have to purchase another chassis much sooner in the case of an eight or nine blade server."
