Solutions Architect at Recovery Point Systems

The ability to leverage multi-tenancy along with immutability is a huge benefit for us

The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top. Veeam Backup specifically has started to streamline their API, and they are doing that with SOS API. They have optimized it. Any of the S3 devices out there that support this SOS API can have far more API calls at once. On our side, that translates to better restoration. With SOS API, it can leverage far more restorations at a single given time or read from the device in simple terms. That results in maximizing the output and throughput from the device itself.

Built-in compression enhances data management efficiency

I have noticed that the technical support for software issues, such as with Spectrum Protect, needs improvement. The case logging process is efficient, but resolving software problems takes too much time. This delay can hinder customers and strain vendor relationships. For hardware issues, IBM handles them efficiently, but software-related support requires enhancement. Overall improvement in support for software cases is necessary.

Enables efficient multi-environment cluster deployment and resource management with versatile features

While VMware vSAN is quite comprehensive, if we are running multiple infrastructures, applications, databases, and other elements, having a diagnostic tool to identify the actual problem area, whether application-side or infrastructure-side, would be beneficial. A proper monitoring tool that encompasses both applications and infrastructure would help in quickly resolving issues.

Quotes from Members

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

Pros

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

"Among its most appealing features are its ease of handling and minimal maintenance requirements."

"It helps simplify our storage, because the user interface is very simple and the installation is easy."

"FlashBlade offers low latency, high throughput, and seamless scalability."

"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."

"The initial setup is pretty quick."

"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."

"What I like best about Pure Storage FlashBlade is its object storage functionality, plus it has fast underlying hardware. Pure Storage FlashBlade is also very stable. I find its stability one of its valuable features."

More Pure Storage FlashBlade pros

"IBM provides exceptional technical support, which I rate as the best along with Cisco."

"The abstraction flair and the abstraction layer. We had a mixture of different storage arrays, and the wonderful thing about SVC is is that it normalizes all it into a single driver. A single view that all hosts see simultaneously."

"There are many benefits to this solution. Storage virtualization and the ability to migrate massive amounts of data to other systems without impacting your client are the most valuable. It is non-disruptive for my users. We migrated 350 terabytes of data in one night to a new machine without a small system going down and a single user complaining about the performance. You have to fine-tune a lot of storage machines constantly for performance and for making sure that they are optimal, but IBM Spectrum Virtualize does this by itself. It does the adjustment on its own, and it does it right. That's what makes it different. I had a huge VSP from Hitachi, which is also a type of virtualization-based engine but with a decent size. It was a continuous performance-tuning exercise. I never had that issue with IBM Spectrum Virtualize."

"One of the main features of Spectrum Virtualize is it virtualizes the servers from the storage. We have a very large infrastructure. A major advantage is when you get the aged storage arrays and you have to replace all of those."

"I like that it can virtualize more than three hundred storage providers."

"Although the GUI from the XIV was used (in my view), IBM has polished and refined the GUI providing a pleasant and easy to navigate GUI experience."

"The biggest benefits of IBM Spectrum Virtualize are its stability, data security, and customer support."

"The ability to have a feature-rich software set which extends the capabilities of the back-end storage arrays."

More IBM Spectrum Virtualize pros

"It helped us survive power outages in one of our data centers, then continued to function without a hitch."

"The most valuable feature of VMware vSAN is you do not have to use additional hardware for storage. The operation of VMware vSAN does not take a lot of effort. If you have VMware technology on your site, then it's easy for the operational support of the system."

"vSAN Health is a feature designed to monitor the health and performance of the vSAN environment. It's crucial for us and our customers to frequently check on this to ensure everything is operating smoothly."

"It is easier to deploy than the traditional SAN."

"The product’s ecosystem is better than Nutanix’s."

"The feature that I have found most valuable is that it is easy to deploy. It is easy to create and delete virtual servers. It is easy to create the load balancing and the clustering."

"I like the tolerance of VMware vSAN."

"The simplicity, as well as the integration with virtualization."

More VMware vSAN pros

Cons

"The feature that we're waiting on is better integration with the cell services."

"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."

"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."

"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."

"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."

"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."

"Its configuration should be easier."

"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."

More Pure Storage FlashBlade cons

"The training program could be improved."

"The integration would be an option that we would like, but I understand that's not how it's going to be implemented."

"t is limited in terms of a single system to eight nodes or four, what they call IO groups."

"The disk reliability is not that good."

"I would like to see more baseline replication and integration with the operating system between Vmware and IBMI."

"Adding features for data deduplication is one area of improvement."

"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."

"The Storwize port is not so stable."

More IBM Spectrum Virtualize cons

"While I like the replication and compression features, there is a problem with them running too slowly."

"On the DevOps side, if there could be more automation it would be more helpful."

"It doesn't seem like it gives the performance that an actual SAN would give for heavy IOPS, read/writes."

"There is a room for improvement on the latest version of compatibility with the VMware product, especially for vSAN and with other vendors on their motherboards and driver configurations."

"The vSan product uses a software system called Vsphere to monitor the system. It is sometimes difficult to manage the PCs within the systems."

"he list of hardware supported should be increased in the future."

"One of the things that we've had challenges with are when we place hosts into maintenance mode. Sometimes doing so triggers large re-sync processes which can be time-consuming and which have, at times, pushed the capacity to the threshold. I definitely think making some changes in that area would provide some big improvements."

"I would like to see more comprehensive lifecycle management. The current path and process for upgrading or updating the firmware, as well as the storage controller software to interact with that firmware, is fairly manual and not very well documented. A little more time and effort spent on the documentation of the lifecycle management for vSan would be really great."

Pricing and Cost Advice

"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."

"I understand that it is competitively priced compared to other brands."

"I feel that the price could always be lowered."

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

"The price could be cheaper."

"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."

"The price is a little high."

"Our licensing is renewed annually."

More Pure Storage FlashBlade pricing and cost advice

"It has a lot of advanced functions for a reasonable price."

"Do a proof of concept, if you are not comfortable jumping in, but do it."

"I am very happy with the pricing. There is no comparison when it comes to pricing. I have looked at all solutions from EMC, Veritas, Hitachi, Dell, etc. None of them compares to IBM when it comes to pricing. I get great pricing from them."

"The entry point of pricing for this product is the most amazing price ever in the industry."

"I think it is a good value for the price."

"We have struggled with Pure Storage, but people are understanding that much of Pure has been consumer grade SSDs. Therefore, when the customer is really understands what they are getting, they realize that IBM presents the same sort of value as existing vendors."

"This solution came as an additional cost for the TSM package we chose."

"Generally the bundled licensing is more cost effective and gives flexibility to the solution. Linking into the Spectrum Suite can also be advantageous, but depends on the scale of the enterprise."

More IBM Spectrum Virtualize pricing and cost advice

"The price is expensive."

"We did consider other hyperconverged solutions. It usually came down to price. vSan was the most cost effective thing."

"ROI from an administrative perspective is clearly much better because I only have to deal with one user interface."

"The first 1-2 years of purchasing vSAN will be expensive. Thereafter, the longer you are running it, the more cost savings you will have."

"I would like to see this technology be made available to smaller businesses, who might benefit from high availability but struggle with the entry fee."

"From a cost perspective, it is expensive. From a usability perspective, it reduces the overhead costs attached to its users' servers."

"If they could reduce the cost, it would be better. Licensing costs are something that they could take care of. If you are a smaller and strong IT team, then VMware vSAN is a very good product. If you want to expand in the service provider space, then you will have to go for an open-source solution like OpenStack. We are now looking at OpenStack because we sell licensing costs. We are a service provider, so the IT component data is a substantial component in our overall costing. We feel that OpenStack might help us to cut down the licensing cost. Therefore, we are looking at SAS storage instead of vSAN. SAS is open source, but it is not wise to have open source without having the backend support. We are using RedHat SAS, and it is an open-source solution. You can also have a free version, but we are using it with support from RedHat so that we have somebody to back us up in case we have a problem. If you do normal business, then IT expense is 1% or 2% of the total turnover. The higher licensing costs sometimes don't make difference to the big companies who are not service providers and are using it only for their internal use. For them, the IT cost is 1% or 2%, but for an IT service provider, the IT costs will go up to 15% to 16% of the total cost of the operations. This is where the licensing costs become irrelevant. For example, the licensing cost of using VMware, VC, and vSAN is 8% of my monthly revenue. Every month, I pay about $35,000, and, with the revised plan, it will be something like $50,000 or revenue of 600k per month, which means almost 8% of the revenue is going into VMware licensing. In a very competitive world, 8% as a cost element is huge. So, if I can bring it down to 2%, I save 6% in revenue expenditure. In terms of profit, 6% of 30% is something like another 25% increase in my profit. My profit can be almost 25%. It would be 20% to 25% in case I am able to handle the licensing costs and bring them to a very low level. Because these IT costs are substantial for us, that is why we are going with OpenStack. OpenStack has a limitation that it requires more hardware. There will be some increase in the hardware cost, but overall we will save 5% to 6% of our licensing cost by using OpenStack."

"Basically, vSAN is a license in addition to that of the classic VMware Vsphere, which is also mandatory."
