Sr, Manager- Network Solution Architect at a energy/utilities company with 10,001+ employees
Comprehensive support and integration ensure smooth cloud infrastructure operations
I may not be the right person to comment on advanced improvements because we are just using basic functionalities. We are getting all the functionalities which we used to get in other OEM rack servers. Potential areas for improvement may include a more flexible pricing model, better technical support, or tutorials from the vendor for users.

One of the products in the market that is the easiest to set up and maintain
Performance and scalability-wise, there are certain areas where the product lacks and needs improvement as it does not provide a lot of fancy features presently. In general, it is a normal product that is good enough for our company. For the time being, my company does not need any extra features.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution is stable."
"The most valuable feature of Cisco UCS C-Series Rack is the use of databases, such as MySQL."
"It is very stable and easy to use. It integrates easily with Cisco's cloud-based UC solutions. There are tools for management that make the management a bit easier, but we don't use them. We don't use what you would term as power users."
"The solution is easily scalable."
"The integration with IT infrastructure is seamless based on our experience."
"The C-series is number one, in my opinion."
"The Cisco UCS Servers are very dependable, and they're very reliable."
"Cisco UCS C-Series Rack Servers have plenty of features and computing and memory power."
"It is a stable solution."
"The solution is very simple to install."
"The product is very user-friendly."
"The hardware is good."
"I would say the stability of the system itself would be the biggest advantage."
"It performs really well, and the price is cheaper than other solutions."
"The most valuable aspect of Lenovo ThinkSystem Rack Servers is the brand name and the service relationship we have with Lenovo."
"The server itself covers all of the bases — my clients are really happy with it."
 

Cons

"The C-Series is not designed to be as scalable. They are designed to have enough RAM and enough CPU on their own side. If you want scalability, it's better to choose the B-Series— the Blade Servers — because those are much more scalable with Fabric Interconnect."
"The hard drive of Cisco UCS C-Series Rack Servers is not very good. I have already replaced three of them."
"Potential areas for improvement may include a more flexible pricing model, better technical support, or tutorials from the vendor for users."
"The product is losing ground to the competition, such as Nutanix."
"The initial setup could be easier."
"Technical support could be more responsive."
"The improvement should be done as per customer requirements."
"The warranty and support periods should be extended."
"Upgrading firmware is easier in Dell than in Lenovo."
"I have a few notification alerts about PCI cards but it's rare."
"To be frank, the technical support from Lenovo's team needs improvement. There seems to be a lack of support, and it is important for Lenovo to address this issue."
"Lenovo ThinkSystem Rack Servers availability could improve. We have been waiting two months for one server."
"Throughout the use of the product, special needs will arise which may require a global need."
"The cost is a bit pricey."
"The power consumption needs to be optimized in Lenovo."
"HP has a riser inside, but Lenovo does not have a riser. It would be good to have a riser with Lenovo. The GUI of the system is really bad. HP has a very good UI for smart memories and everything inside, but in Lenovo, we have a black-and-white UI. HP right now manufactures a server with scalable SP1 and SP2 on a single machine, which is not the case with Lenovo. They are changing the machine. For SP 1, there is one server, and for SP2, there is another server, which is really bad. In HP, we can use two models of processors in a single case. Lenovo should also be improved to have SP1 and SP2 scalable processors simultaneously on a single machine. They should not release another machine. This issue is also there in H3650 severs. They are all inside, but only V3 CPU or only v4 CPU can work, whereas, in HBG9, we can deploy V3 and V4 simultaneously. Lenovo also needs to advertise more because I can't see advertisements anywhere."
 

Pricing and Cost Advice

"We have to pay for the VMware and Cisco licenses."
"The price of the Cisco UCS C-Series Rack could improve. It's a little more expensive in comparison with Dell or HPE solutions."
"If they plan to expand their infrastructure in periods, then simply Cisco is not a good choice."
"Licensing fees are paid on a yearly basis, which is only $2,000 or $3,000."
"The price of Cisco UCS C-Series Rack Servers is approximately 20 percent more than other solutions."
"The price for Cisco is a bit higher than its competitors. We paid 40k for one server."
"The pricing is expensive."
"This product is slightly more expensive when compared to others."
"The cost of the solution depends entirely on the client. There are not any additional costs other than the standard licensing fee."
"Lenovo ThinkSystem Rack Servers can be categorized as a product falling under an affordable price range but more expensive than its competitors."
"It is too expensive. Because we are a university and we have to look for our money, many times we buy some refurbished machines or equipment at reasonable prices from IBM or Lenovo. We are a little bit limited in terms of money, and we buy as much as we can. If they were cheaper, we would buy more."
"It is expensive compared to other vendors."
"In India, the solution is cheap compared to its competitors."
"The price of Lenovo ThinkSystem Rack Servers is competitive."
"I don't know the exact amount of money, but when I compared it to Dell or HPE, Lenovo was the best when it comes to price and equipment."
"The licensing cost is the same as HP. It doesn't have any additional cost. However, the price, for example, for the memory option, does not match other vendors such as HP or Dell. They should work on the pricing of Lenovo. It is a great competitor, and it should compete with the price."
