What do I think about the stability of the solution?
It's very stable.
What do I think about the scalability of the solution?
It scales for the kind of customers that we have.
How are customer service and support?
We'd like to get more access to level-two engineers. Sometimes its been a difficult time explaining the problem to level-one people. This process is a little bit time consuming.
How was the initial setup?
The initial setup was straightforward.
What about the implementation team?
We did implemented it ourselves.
Which other solutions did I evaluate?
When we deployed flash cache, there was no alternative for it. It was the only available cacheing solution.
What other advice do I have?
Flash cache is a great product. If it matches with the workloads, you should consider it.

Lead Technical Architect IT at a healthcare company with 1,001-5,000 employees
It saves a lot of time and minimizes downtime, which is important because we're a hospital and we can’t afford much downtime. I'd like more automation of the expanding aggregates and discs.
What is most valuable?
- Snapshots
- Mobility of data
- High Availability
How has it helped my organization?
It saves a lot of time and minimizes downtime, which is important because we're a hospital and we can’t afford much downtime. If they can stop all downtime, it would be a big benefit for us and our patients.
What needs improvement?
I have a very small feature request: more automation of the expanding aggregates and discs.
What was my experience with deployment of the solution?
We've had no issues with deploying it.
What do I think about the stability of the solution?
The stability is very good.
What do I think about the scalability of the solution?
We have six PB of data, and have had no problems with scalability.
How are customer service and technical support?
The technical support is good.
Which solution did I use previously and why did I switch?
We have had NetApp for a long time, and were one of the first customers in Belgium.
How was the initial setup?
If you are new, you have to learn the system, but once you know how it works, it doesn’t take much time to expand or install a new system. It was not difficult at all to learn the first time.
What other advice do I have?
Over the past few years, they have evolved a lot in manageability and automation, so we are happy with the direction they are going in. They haven’t lost their eye on stability as well. Lots of new features without sacrificing anything.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.

Storage Administrator at a financial services firm with 51-200 employees
Its data compression saves a lot of capacity we'd otherwise have to have. It could improve by better integrating with other technologies like VMware, as there are some version conflicts.
What is most valuable?
- Clustered data ONTAP
- Data compression
- High Availability
- Snapshot technology
How has it helped my organization?
It helps us reduce costs because its data compression saves a lot of capacity we'd otherwise have to have.
What needs improvement?
It could improve by better integrating with other technologies like VMware, as there are some version conflicts. When you are using the newest storage virtual console, you cannot use VM Wall, the VM-specific firewall.
For how long have I used the solution?
We have been using it for a year for SQL databases.
What was my experience with deployment of the solution?
We've had no issues with deployment.
What do I think about the stability of the solution?
It's very stable and we've had no problems in the year we have used it.
What do I think about the scalability of the solution?
It has scaled to our needs.
How are customer service and technical support?
Customer Service:
Customer service is good; we've had no problems with them.
Technical Support:Technical support is good; we've had no problems with them either.
Which solution did I use previously and why did I switch?
We used HDS before NetApp and we switched because of the snapshot technology and high-availability function.
How was the initial setup?
The initial setup was pretty straightforward, the implementation of the system was easy, and we had great support from the NetApp team.
What about the implementation team?
We used a vendor team who had strong expertise, and we are happy with the implementation. It’s important to have NetApp technicians implement the solution because it is helpful to have some experts.
Which other solutions did I evaluate?
No other options were evaluated.

Systems Engineer at a government with 501-1,000 employees
We were able to restore a lot of data in about an hour, although NetApp OnCommand, which has been a lot better recently, could still be made faster.
What is most valuable?
The integration with VMware is the most valuable feature for us because we run a lot of VMs and the backup is very good when you run your VM in NFS.
How has it helped my organization?
We had a case when they had to restore a lot of data. We went back one hour and got back everything. The restore itself only took about an hour.
What needs improvement?
Some of the tools could be improved like NetApp OnCommand. This has been a lot better recently, but they could make it faster.
For how long have I used the solution?
We've been using it since 2005.
What do I think about the stability of the solution?
It's very stable and I’ve never experienced any problems in 10 years.
What do I think about the scalability of the solution?
It scales to our needs.
How are customer service and technical support?
Customer Service:
8/10 - only because it is impossible to have a 10, as there is no one that good. We’ve had a good experience with their customer service.
Technical Support:The solutions that are present on NetApp’s website are enough usually, but when it is tough for me to resolve it on my own I go to our consultant.
Which solution did I use previously and why did I switch?
We did a long time ago.
How was the initial setup?
Initial setup was pretty straightforward. We started on a small scale and built it up.
What about the implementation team?
We implemented it in-house, but we use a consulting company to help. Now, we run it on our own.
What was our ROI?
It fulfills the needs we have for storing data well. We had a lot of storage spread out over many devices from many vendors and now everything is consolidated. It saves a lot of time.
What other advice do I have?
Ask other people who use it as references are really valuable.

Systems Engineer at a non-profit with 501-1,000 employees
The integration with Windows for SQL exchange is critical, but it doesn't allow for live deduplication.
Valuable Features:
- High Availability – most important thing with all big storage systems
- Flexible – it uses all different kinds of protocols (SAN, fiber channels)
- Virtual Management Console – helps with and integrates with vSphere. I’ve deployed it, but haven’t configured it. Looks really promising.
- Snap Drive – integration with Windows for SQL exchange is critical
- Can update without taking the system down
Improvements to My Organization:
It’s a High Availability environment in which I haven’t had problems. We’ve only had one disk fail in a year. Quality of product is good.
Room for Improvement:
Tegile offers live deduplication. And NetApp can only be scheduled to dedupe in the background or for later.
Also, the web page for downloading software could be more efficient (for example, getting instructions takes a few clicks). Make it easier for customers to download software.
Initial Setup:
The instructions didn’t provide for re-configurations from scratch and tech support were stuck too. The person who configured before had installed NetApp 8.2 on 7 mode. 8.3 didn’t support 7, which I wanted to do, so that’s why I had to reconfigure from scratch.
Other Advice:
First, make a lot of calculations of how much data you’re going to use and how much you’re using now. Compare the two and look into how you configure storage solution. How much data, how to split, etc. If you can’t spend that much on storage, you need to determine how to follow best practices to get as much storage as possible for the money. For example, if you have five shelves, you don’t need to worry about LUNs going offline. But if it’s just two shelves, like I have, you must be very careful about provisioning storage and use as much as possible.

Sr. Storage Engineer with 1,001-5,000 employees
It's reliable and scalable and, in the event of failure, it’s highly available, but Unified Monitoring loses a bunch of funcationality that its previous versions had.
What is most valuable?
The performance allows me to provide backend storage for large number of VMs and databases at a competitive price point.
What needs improvement?
Unified Monitoring v6.2 loses a bunch of functionality that previous versions had. For example, I took a cluster out of Unified Monitor, but Storage Monitor was still alerting me about it. 6.2 is not as comprehensive, but Unified Monitoring 6.2 will only be useful when it does everything. Insight’s price is just too expensive and unreasonable.
What do I think about the stability of the solution?
It's pretty stable, even if it runs into something freaky, it keeps going. For example, mysterious a reboot, and nobody notices. It keeps working.
What do I think about the scalability of the solution?
It scales to a point, and then you buy more hardware. Doing a head swap (swapping out controllers) is not as easy as it used to be.
How are customer service and technical support?
It's better than Oracle, but actually pretty good. They're responsive, and help resolve situations. We have had a couple of issues, but 99% of the time, they get me an answer, although it may not be what I like, but it’s a definite answer within a reasonable time frame.
Which solution did I use previously and why did I switch?
It's complex, not a trivial task. We can unbox it and deploy. There are many unpublished tech tips that NetApp engineers get that customers don’t (for example, how to save a disk).
What's my experience with pricing, setup cost, and licensing?
The price-per-gig makes it the most expensive storage, more than EMC VMAX. So I’d like to see more aggressive pricing.
What other advice do I have?
It's losing points on its value. The performance is nearly perfect, but it’s really expensive.

Database Manager
Since updating to Dynamix AX 2012, not a week has gone by that we haven’t fired up a clone to test a user, code, etc.
Valuable Features
- Clone – we updated to Dynamix AX 2012, and not a week has gone by that we haven’t fired up a clone to test a user, code, etc.
- Disaster Recovery suite of functions
- Quick backups that don’t impact system
- Refreshes test environments quickly
Improvements to My Organization
- Reliability – hardware performs well, we’ve never had problems
- Great support from Sirius
- We’re able to recover a file if we need to
Room for Improvement
We use mirroring a lot, and if it had snap manager for SQL included, we could do that from one location.
Stability Issues
Rock solid. I’ve been at Wilson for three years and have also used it before at another company. We have a disk go out every once in a while, but no issue with FAS.
Scalability Issues
In the last growth, we went from a 3250 to an 8020. We’ve set it up to grow out easily by just adding trays.
Customer Service and Technical Support
Lately, a little slow to respond, but once you get someone, they’re very knowledgeable, although I haven’t had to use it a lot.
Initial Setup
I was familiar with 3250’s from another company, so I knew how to use the software, but Sirius helped us. So in that regard, it was straightforward.

Storage Adminstrator at a energy/utilities company with 1,001-5,000 employees
It has the capability to use SAN, so it has a broad spectrum of use. I'd like to see more cohesiveness with a unified manager.
Valuable Features
- Software features, such as being able to do snapshots and file system optimization
- High Availability -- components fail so this is a nice feature to have when failing over. There's no downtime, so we don’t lose data.
Improvements to My Organization
Good bang for the buck. Also, we use NFS generally, but FAS has the capability to use SAN, so it has a broad spectrum of use.
Room for Improvement
Tough for me to answer because I’m limited in my role, but the one thing I’d like to see most is more cohesiveness with a unified manager. I like the end product, but it’s not really all integrated and is convoluted with different managers. I would ike a single pane of glass, a single dashboard.
Deployment Issues
We see a lot of bugs in roll outs, and sometimes I think the first GA are late-beta deployments. My impression is they could have let it bake a little longer. But it could also be because of some of the environments it deploys in.
Stability Issues
Snap Manager v3.3.1 is a little buggy and NetApp doesn’t offer training course on it. So it could be what I’ve been taught by other people, or it’s in fact buggy, but likely a little of both. Hopefully they made improvements on 3.4.
Scalability Issues
7-mode scales very well. I’m even more impressed with where they intend to go with cDOT, but it may be rolled out prematurely.
Customer Service and Technical Support
Tech support is usually pretty good, but occasionally there are some things that occur only on our site that tech support has issues.
Other Advice
Plan ahead and make sure you right-size it. How much head room do you really need? How many spindles are you going to attach? Are you really going to share workloads or do you want to separate some of those? We don’t segregate our infrastructure, which I don’t like, but all that costs money. But you should make sure that you have failover.
