What is our primary use case?
I provide IBM FlashSystem to my customers and host it on the GBM private cloud, to give them the best services. I am working on a project to replace an HP Primera with an IBM FlashSystem 5200. This solution consists of two boxes connected with the remote mirroring feature of the FlashSystem. Each box has about 30 terabytes of storage and is replicated using a flash copy. The boxes are connected to a Power System running AIX, and I have implemented the EC tier with multiple layers of disk including MV, SST, and rotational disk. Additionally, I have set up Spectrum Protect to make backups to the TS 4300 tape. This project is currently being implemented and should be completed within the next month.
What is most valuable?
At the FlashSystem level, customers are especially fond of multi-tier and distributed rate systems, particularly the dynamic rate six arrays. They appreciate the extra layer of protection this provides, as well as the Easy Tier feature which is analogous to IBM’s FlashCopy. Customers find the FlashCopy feature highly beneficial, and the feature often comes up in conversations.
Customers are delighted with the new version of IBM's Virtualize system because it allows them to easily expand arrays with a single disk, something that was not possible in the past. They appreciate the added convenience of being able to incorporate multiple items indistinctly into the array.
What needs improvement?
Our customers have raised concerns about the limitations of the FlashSystem 5200 and 7300, which only offer a 32-gigabyte connection. This presents an issue for customers whose other infrastructure, such as old HBA cards, is limited to an eight-gigabyte connection. To maintain the recommended N minus one connection, the customer must use the 32-gigabyte connection, which is not ideal. To provide more flexibility, our customers would prefer to have a 16-gigabyte connection on these small boxes. The customer was initially unhappy with the situation because they had to replace all of the eight-gigabyte connections in their sixteen servers in order to migrate to a new storage system. Furthermore, to remain competitive, the customer had to be given the machines for free. While the customer accepted this, it was still a displeasing and uncomfortable experience for them. However, the machines were eventually sold and installed, leading to a satisfactory outcome. Despite this, the customer was still left with a feeling of dissatisfaction from the negotiation.
For how long have I used the solution?
I have been using the solution for several years.
What do I think about the stability of the solution?
I give the stability a nine out of ten. The latest versions of Virtualize, from 8.5 and above, are highly reliable. I have not had any complaints from customers about them.
What do I think about the scalability of the solution?
I give the scalability a nine out of ten. This solution is highly scalable, allowing for both side-by-side placement and clustering. This makes it an ideal option for me due to its scalability.
How was the initial setup?
My technician told me that the initial setup of this machine is much faster and easier than with previous versions, and they were very pleased with it. Though I haven't experienced it myself, I understand the positive experience it has provided.
For example, with the small model, we can configure the machine to enable us to access the SAN. This includes configuring the worldwide name and getting familiar with the SAN experience. It typically takes around three to four hours to set up boxes in the morning, depending on the size of the array and any specific configurations that the customer wants. For smaller models, this is usually the case. For larger models, the setup time may vary but is estimated to take no more than four hours for arrays up to 30 terabytes.
For deployment on the small machine, one to two people are typically required, as it is necessary to have two people to rack the machine. For larger machines, three people are usually used for racking and setup. The large machines are the DS, the Enterprise, and the 7300.
What's my experience with pricing, setup cost, and licensing?
I'd rate the basic licensing and the Virtualize software a ten out of ten, and the extra Spectrum and other an eight out of ten. However, if we combine the basic and advanced licensing, I'd give a score of eight out of ten.
What other advice do I have?
I give the solution a nine out of ten because of the solution's flexibility, scalability, and great prices. Last year's performance was remarkable, and I expect the same this year. IBM FlashSystem truly exceeded my expectations.
I suggest using the ESS for planning and ensuring a thorough conversation with the customer about their desired outcome. Proper planning is essential for successful implementation; if the planning isn't done well, it can lead to having to redo the work. My advice is to plan carefully and talk to the customer to make sure we understand exactly what they need and how to deliver it.
