Offers cost-effective storage for small companies with budget constraints

IBM FlashSystem 5300 is offered at a very low cost in Israel, which is advantageous for small companies. However, other features like deduplication and compression do not perform effectively. The price sensitivity makes it a viable option for clients with budgetary constraints, as it allows us to secure deals based on the cost rather than advanced performance.

Good value for money but issues with modular scaling

IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness I've been using IBM XIV for two and a half years. IBM XIV is stable. IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger…

Quotes from Members

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

Pros

"The Flash core models offer amazing performance."

"The pricing is reasonable."

"The valuable features are high availability, compression, and a failover mechanism. It's a very highly available storage solution."

"IBM FlashSystem has been stable in our operations."

"No queuing and high ops, speed, and performance."

"Ability to manage third-party arrays and virtualise them: One screen to control multiple arrays. Simplified administration."

"The most valuable features were the performance of the array, i.e., very low latency and high IOPS. Plus, the management interface is very easy to use."

"IBM FlashSystem is the best solution for storage virtualization."

More IBM FlashSystem pros

"Installation is amazingly easy."

"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."

"The performance and robustness of the systems are very good."

"Hands down, this is the easiest storage platform on the market to manage."

"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."

"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."

Cons

"The generic functionality of IBM FlashSystem, IBM always dismisses using file share or sharing protocols inside their storage hardware, and they only focus on the block-level storage."

"There is room for improvement in the troubleshooting part, specifically related to IBM Spectrum for Insight. Customers are uncomfortable with remote access, which affects automated remote support."

"They can include Amazon file system S3 protocol in the upcoming releases. It is a cloud file system. IBM FlashSystem doesn't have this feature in the box for high-end or mid-range. We have got requests for this from customers because we need to use S3 for EDI application storage. At the beginning of every year, IBM releases firmware. When I find any bugs in the firmware during the year, I am unable to find any information from IBM regarding the bug. I need to open a ticket, and the IBM engineering team makes a patch only for me. This patch is not public. By creating a customized patch for a client, they don't really solve the issue for everyone. If multiple users have the same bug, IBM should upload the patch on the official website so that we can download it. IBM FlashSystem has a monitoring tool in the box, but it is not advanced. I need a more advanced tool for more advanced equations and monitoring. All top three storage vendors, that is, EMC, IBM, and Pure Storage, don't have a powerful monitoring tool. To monitor our box to show the statistics for I/Os and latency, I need to pay for extra software. The built-in monitoring storage is not mature enough to handle all requests and generate all reports that I need. They can include the functionality to stretch a cluster natively without using any additional boxes. In addition, there are some features that EMC has integrated with the box. These features are not available in IBM FlashSystem."

"Our customers have raised concerns about the limitations of the FlashSystem 5200 and 7300, which only offer a 32-gigabyte connection."

"The solution has a low number of NVME host attachments at 16 per IO group over the fiber channel."

"The data reduction pool feature sucks and is not recommended for use with heavy workloads."

"The support could improve by allowing you to speak to someone when you call rather than them calling you back. However, once we do have contact with one of their technicians they are excellent."

"I know they have a flashcopy manager, but it is extra software, an additional license, and some customers don't like to add addition costs to their infrastructure. If IBM could create, or include snapshot management within the GUI, that would really be helpful."

More IBM FlashSystem cons

"Until the drive is replaced, the pool_resizing is locked."

"I would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."

"This product was not a good fit for our organization as we have a ton of latency sensitive applications and XIV was not able to keep up with IO + latency demand."

"I encountered stability (performance) issues during enclosure or disk rebuild. Also some power supply issues due to malfunctions of circuits. Sometimes "internal" Snap sessions hang and consume pool capacity."

"The change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."

"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."

Pricing and Cost Advice

"The pricing is competitive in our country."

"The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go."

"IBM V7000 has a new license and price structure which provides intuitive licensing based on the functions customers wish to enable and use the most."

"The price depends of the technology that our customers need. The price can come at a lower cost but this may increase as storage is added."

"The pricing has been very competitive for the last few years. IBM got to the point where they changed the pricing model and we feel very comfortable with the pricing. It's very competitive. Over the last two years, IBM has been coming up with all kinds of interesting promos, especially for the SMB systems. That makes it very competitive price-wise and in terms of performance..."

"The cost is pretty high in terms of licensing. We pay at least $100,000 USD in licensing fees for the storage."

"The cost of the IBM FlashSystem is lower than the HPE solution."

"Pricing can be considered as per market competition."

More IBM FlashSystem pricing and cost advice

"We have a five-year total cost of ownership where we pay an initial amount and then annually for maintenance."

"If you are going to use the product behind an SVC, IBM will price the units lower, since you are likely not to use any of the advanced copy services."

"Licensing is straightforward."

"No-license-required policy, unlike others where you need a license for everything. Just pay once and forget about licenses."
