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 most crucial feature of IBM FlashSystem is compression."

"Something that historically had been hard and difficult became a background task, once the old array was managed by the V7000."

"IBM FlashSystem is a very stable solution and its default rate is low."

"FlashSystem offers proven technology in a compact package."

"Virtualization of external storage, while adding cache and speed to the external storage."

"The initial setup is straightforward and can be done in an hour and a half by one person."

"Virtualization of external storage, while adding cache and speed to the external storage."

"The valuable features for us are the extra add-ons, such as the FIM provisioning, the compression, the disaster recovery capabilities, and the storage pooling functions."

More IBM FlashSystem pros

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

"For us, the XIV is pretty much set-it-and-forget-it storage."

"XIV setup is very straightforward and easy to configure."

"Implementing Remote mirroring and local Snaps is very easy."

"The product is exceptionally reliable and very easy to manage."

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

"Installation is amazingly easy."

"IBM XIV is attractive because it gives value for money in terms of features."

More IBM XIV pros

Cons

"It could be easier to implement."

"The initial setup is complex."

"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."

"A big area for improvement is that the data reduction pool feature is not recommended for use in a production environment because it has stability and performance issues."

"This solution could be improved by offering greater amounts of storage."

"The price is very costly, which could be improved."

"The solution's pricing is a bit high so there is room for improvement."

"Replication features need improvement. Currently, they are there in the product, but I'm not sure as to how it works exactly."

More IBM FlashSystem cons

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

"Until the drive is replaced, the pool_resizing is locked. This has been an issue a lot of times, especially when the contract says IBM will not replace disks until three drives fail."

"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."

"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."

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

"I guess we'd like to see the XIV keep pace with how storage is going in terms of speed and latency."

"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."

"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

"They've been much more aggressive in the last five, six years than they were before that."

"This solution is expensive compared to other solutions."

"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."

"I would rate the pricing of this solution a four out of five."

"My customers got the IBM FlashSystem bundle offer. It was a one-time purchase for three years of service. The price would depend on the storage size and could reach between $25,000 to $55,000."

"This is an expensive product and if the price were reduced it would be better."

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

"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..."

More IBM FlashSystem pricing and cost advice

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

"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."
