DataCore SANsymphony Reviews

The most useful feature of SANsymphony is that it's able to manage any brand of block storage.

If it could integrate to a cloud gateway, then we could carry it directly to storage, instead of having middleware in between the storage and the cloud.

It's a very expensive solution, and the licensing costs should be lower.

I've been dealing with this solution for seven to eight months.

It's very stable, but you must know what you are doing because you need to have sufficient memory processing in order for SANsymphony to work properly. Once you have that down, it's actually quite easy to manage.

Scalability is easier because everything comes in pairs. Everything you need to do, you have to do in pairs. For DataCore SANsymphony, you don't need a witness node. You can actually run in pairs, and you can upgrade in pairs. You can find support for up to 64 nodes, if I'm not mistaken. It depends on how you want to design your architecture.

Based on my experience, their technical support is very good.

The initial setup is very straightforward.

One person can easily manage the entire software. There is a learning curve, and you need to understand the features, how it works, how to create your storage pool, and how to tier your storage pool. Once you understand those things, everything is actually quite easy and streamlined. You just need to know the basic architecture.

We have licensing costs on a yearly basis. They charge per terabyte, so in terms of cost, it can be very costly.

They have three different features, and you have to pay extra for those.

If you have multiple block storage, as in a silo, then you can use SANsymphony to manage the storage from one management portal. You can also tier the data from storage, say, for example, from HP storage to Dell storage, transparently. You can also do storage migration without any downtime.

Compared to VMware vSAN on Nutanix or VxRail, you need a minimum of three nodes, two nodes and one witness. However, for DataCore SANsymphony you don't need a witness node.

DataCore SANsymphony is very good and very solid. In fact, it's almost 20 years old, but the pricing can be an issue.

We utilize the software-defined storage for our database systems and virtualization environments (we have multiple). One detail we utilize most is the HA provided by the vendor. We have two “legs” for connectivity to our SAN. This provides two logical locations in two physically separate data centers. This keeps our DBAs and admins happy. We can perform changes and updates on one side while the app (DB) data is accessible on the other. The data is synced almost instantly when both sides are up and operational. This allows us a lot of flexibility.

When you have to meet data latency and accessibility requirements you will need to look at this software offering. Our developers and DBAs require uptime and redundancy. This has improved our operational offering to our customers. The end-user finds it fast and reliable. The software works well no matter what storage vendor we put on the back end. We can check storage from startup ABD or price from vendor XYZ. This improves our flexibility and cost savings as we rely on the software and not on a product or manufacturer that locks us in.

Active-active is the most valuable aspect for us. The reason being, we can run our clusters on one side knowing our data is available in the other data center. There is simple management via GUI or command line. 

The software just works and is reliable. Downtime due to storage maintenance or upgrades is long gone. We have multiple types of software running to differentiate our applications. This gives us more value due to the fact that we can segment by application if needed. The bottom line is the software is what runs our applications on whatever storage vendor we choose - and it does so reliably.

One area the company can improve upon is the use of other software. Right now, the version used is run on Microsoft Windows Server. Having a Linux version or even an appliance would be better as it would eliminate the use of additional licensing for another piece of hardware. While the Windows server has gotten more reliable, I would like it more if it would not be dependent on Microsoft Windows Servers. 

Improving the GUI would be another feature where they could add to the software. They should make it more intuitive by simplifying the layout.

I have been working with the software for over five years. 

The software is very stable.

The scalability is very good. 

Customer support is hit or miss. There are good technicians, however, some are not so good.

Positive

We did not previously use a different solution. We have been using this software for some time now.

You may want to get professional services to start the setup if there are key features you want to be implemented.

We had a very good team implementation.

The software paid for itself long ago.

I'd advise users to do their homework. This software gives you good reliability and performance.

We did not evaluate other options.

I like the product and will continue to use it well into the future.

The solution is used for the provision of high performance and high availability block storage. By using auto-tiering, many applications can benefit from the high performance of current NVMe SSDs. At the same time, cold data is kept on low-cost storage resources.

The separation of data streams from different applications (e.g. SAP HANA, SQL server, virtualisation) also increases overall performance and availability.

The use of snapshots for data backup is already planned and scheduled. For this purpose, Veeam Backup 11 will be connected to SSY. The backup will then be LANless via Fibre Channel.

Among other things, we used SSY to bring a Splunk installation onto the existing central DataCore storage. Continuous data transfer rates of up to 2.6 GByte/s (16GB Fibre Channel, dual fabric synchronously mirrored systems over 20km) were also achieved.

The project was also much cheaper and easier to implement than any comparable solution.

The services already running (databases, virtualization) are not affected and run with the same performance as before the expansion.

Veeam is now configured to use storage snapshots. This reduces VMware snapshots to a minimum. The backup runs via Fibre Channel and relieves the LAN.

Synchronous mirroring was a prerequisite for the project. Two data centers are used, which are connected via two different WAN routes. 16G FC is used via the WAN. The "Systems managed Mirroring" feature was used for this.

Another feature that makes high performance possible is "pool striping", where accesses are distributed over a larger number of external data volumes (LUNs). The limiting factor for performance here is the external storage that is connected to the DataCore servers.

Snapshots are also an important feature. In connection with external applications, these enable an improvement in data protection.

CDP is an important feature for avoiding data loss in the event of ransomware attacks. You need more storage capacity, however, you get the possibility to return at any time and use the data saved up to that point. The recovery is much faster than with a classic restore.

With dedupe and compression, we can now save considerable capacity. An expansion of the capacity and thus the purchase of new licenses are thus avoided.

For an upcoming release, I would like to see a function that can manage the storage of multiple Datacore servers in a kind of "erasure coding". This would simplify scaling and make SSY more competitive with other providers.

NVMeoF should be implemented. This protocol will play a major role in storage infrastructure in the future.

Network protocols are becoming increasingly important. For future projects, protocols such as RoCE should be implemented. Especially in LAN infrastructures from 25G, a simpler and high-performance SAN infrastructure could be built here. The costs should be lower compared to Fibre Channel.

Improving support will be very difficult as it is already one of the best in the IT world.

I have been implementing SSY very successfully with many clients since 2008.

The system runs very stable. Through the use of server pairs, there is no more downtime. The storage service is always available, even if maintenance has to be carried out or a hardware defect has to be repaired.

The performance can be scaled very easily by adding data devices of the desired performance class.

It is also very easy to expand the capacity. By adding low-cost storage, cold data can be stored there. This also ensures that the hot data can be accessed with high performance.

Datacore offers one of, if not the best, technical support teams in the industry. Every request is handled very competently and in a short time.

The SEs are also very well trained and competent. They are always available for questions and are also very willing to give suggestions and information.

Positive

We previously used Netapp Metro Cluster. We switched due to the costs for the infrastructure (Metro Cluster) were too high. The performance was also no longer sufficient. The solution was too inflexible.

The implementation is somewhat more complex than with simple storage. In addition to the actual storage resources and the SAN infrastructure, the x86 server with Windows Server and SSY must also be installed.

The configuration of the storage is easy, as it is best to create many identical volumes and present them to the Datacore server.

These volumes are then included in the pool within SSY and centrally managed there.

The SAN configuration includes the construction of a FrontEnd, BackEnd, and Mirror layer. It is a little more complex, but not complicated.

The host systems access the resources via SSY, so these must also be configured in SSY. On the other hand, only the SSY servers need to be set up on the storage.

Being a DCIE myself, I did the installation.

Since the environment is dynamic (for example, changes, extensions), the ROI is not easy to determine. However, the TCO is more favorable than with other solutions.

Good planning is always very important. SSY is very flexible and can cover very different requirements. Therefore, it is important to keep a close eye on the requirements. If you have questions before implementation, ask support or a partner.

Also, pay attention to licensing. It may be cheaper to license a few TB more if you can make a jump in the discount scale.

Also note: Using DAS (internal storage) can be very cost-effective compared to external storage.

We considered different solutions such as Netapp FAS-Series, HP MSA, and 3Par.

I am glad to have used SSY. The solution is very stable and performs well. It requires very little effort.

What you do have to do, however, is regularly apply Windows patches. To do this, the node has to be restarted. You should therefore always use a pair with synchronous mirrors to avoid downtime.

The product is primarily used for providing block storage space for the virtualization environment.

The server nodes caching algorithms will speed up your SAN storage performance, even if you are already using a high-class FC attached enterprise storage system.

The DataCore is open in order to attach a lot of different storage subcomponents.

The SDS is not dependent on a special hardware vendor. You will be able to mirror between different vendor systems if you like/need to. For example, to mirror data between one node with locally attached storage and the opposite node with an FC attached NetApp system. The data migration between old and new HW is quite simple.

The DataCore system has been rock solid since we have been using it - from 2007 on.

The caching functionality, which could speed up your attached storage, is great.

We use the reserved x% of space for free for new writes as additional speed improvement for multiple tier pools.

DataCore will reserve a percentage of your storage tier and tried to keep it free to write directly new data into it. In that case, your new writes will go directly in the free space of tier 1, which is the most common and fastest one. Afterward, data will be kept in tier1 or destaged to other tiers (2, 3, 4, etc.). This setting improved our SAN Speed for the complete pool.

It would be ideal if they were providing archive licensing with the ability to create a second pool on existing storage nodes. Maybe they could do it with limited max IO and/or without auto-tiering capabilities for the archive pool - to avoid interference with the performance pool.

I've used the solution since 2007 when the product was called SAN Melody.

The solution has 100% storage availability and we've had that for more than ten years.

There is scalability without any limit.

Customer Service is very fast. There is a high level of expertise and they are willing to help and assist you. They are industry-leading, I would say.

Positive

The local storage was used before and we found that it was not flexible enough.

The initial setup was straightforward and easy. With good planning and knowledge of your own environment, the setup works like a charm.

DataCore provides well-documented configuration guides.

It was a combined installation. Would like to say that the vendor assisted us.
Their knowledge and support were great, as was our internal expertise.

The availability is the best ROI.

DataCore is a good and valuable solution. The licensing costs depend on the storage and the volume of use. They were leveling on a good basis.

We did not evaluate any other solution.

DataCore is only as good as your plan for your environment. First, you need to know your own environment, including: 
- storage space
- throughput
- burst IO
- avarage IO. 
- good planning and testing.

Perfect choosen hardware is one that fits your needs. If you have that combined with DataCore, you will guarantee a success story.

We work with the enterprise edition, SANsymphony V SDS.

The solution is geared towards small and medium-sized businesses, with two or three node clusters supporting business continuity and nonstop operations of virtual machines or servers. This makes the solution very stable, cost effective and simple to administer and maintain. 

The solution's most valuable feature is its versatility, with there being support for all new hardware technologies and platforms, disc mirroring and very effective auto tiering. This translates into very advanced storage features, accompanied by a cost effective application or license.

The so-called hyperconverged infrastructure edition, sometimes knows as vSan, should be addressed. It is one component of the solution. Yet, DataCore is less competitive than certain other manufacturers, such as EMC, Cisco, and VMware vSan. It is competitive when it comes to a general purpose software defined storage solution. As such, a hyperconverged infrastructure solution could be improved.   

The solution could be better packaged and marketed. 

When it comes to a simple 2 node cluster business continuity solution for SMB companies, the downtime can be expensive.

We have been working with DataCore SANsymphony SDS for eight or nine years, although we are talking about a relatively new edition which was published several years ago, possessing similar technology. 

We have worked with the solution over the course of the past 12 months. 

DataCore SANsymphony SDSOne should not hurry with Microsoft patching and should try to use newer, stable versions of DataCore and Microsoft Windows server.

These are the perquisites. When fulfilled, DataCore works really well and is stable.

The stability is high and extremely good. Once set up properly, the stability really works. 

The scalability is excellent. 

We provide support. As such, we usually help to resolve issues arising with vendor DataCore.

DataCore's technical support is very good and I rate it as a nine out of ten. 

The installation is nice and straightforward. 

The length of deployment varies with the complexity of the customer's environment and can last from three to five days, including the planning and optimization.

Generally speaking, we do installation.

There are usually two people involved in the deployment and the main channels of the solution, one of whom is experienced with the Microsoft infrastructure and server, the set up and the configuration. The other person has experience in networking and the configuration of the network, interconnecting the nodes. So, there are not a lot of people involved. 

The solution is cost effective. 

When it comes to a simple 2 node cluster business continuity solution for SMB companies, the downtime can be expensive.

The solution has very advanced storage features, accompanied by a cost effective application or license.

We are a reseller.

There is DataCore and we are Datatek. We are just talking about similar names, Datatek being a DataCore reseller.

I rate DataCore SANsymphony SDS as a nine out of ten. 

SANSymphony is used to provide HA storage block services to the vSphere Streched Cluster. The backend virtualized storage is a mix of internal node storage and SAN (Dell Compellent, IBM Storwize). It can be fiberchannel connected or iscsi or both.

By using this solution we provide a High Availability storage solution.

We can do the running of VMs in classic Windows or Linux workload and Citrix virtual Apps.

This is a software solution, so new functionality does not rely on any hardware.

SANSymphony allows us to separate the storage software from the hardware. That way, we can replace or add any backend in the cluster without downtime.

This ease of adding or removing storage allows us to control costs.

All maintening operations can be done without downtime as well. The team is happy due to the fact that they can do the operational tasks during day without impact on the production.

It helps us control storage costs.

This solution is very flexible. We can have 2 physical DataCore nodes with backend storage virtualized or we can have internal disks on the main site and hyper-converged 2 nodes on Robo sites. All this is managed from the same console and with the same functionnalities.

Continuous data protection (CDP), can be used to "protect" again ransomware by recording all write on disk in a log. You can recover your data with incredible time granularity.

The parallel I/O function is very useful to have good storage performance.

The ability to do asynchronous replication to a third site is a easy way to create a disaster recovery plan. 

Veeam Backup integration is a good new option. Now we can leverage a Datacore storage snapshot to do our backup without VM by using vsphere snapshot.

Datacore is developing a new WebUI with new dashboards. It is a good idea as the classic GUI is lacking dashboards. 

We need a better view to analyze the auto-tiering feature (like in DIS) to easier decide what type of storage we need to add. The current view in the GUI is too simple and we cannot see clearly cold data or hot data.

You can report all you want. There are a lot of counters usable in the console. However, there are too many. They need to create some pre-defined graphs or reports.

We have been using this solution since 2016.

It is a very robust solution. I have never experienced to total crash. I would like it if it continues this way.

Due to the design, the product has unlimited scalability.

The support team is really good. The product is frequently updated.

We previously used IBM Hyerswap and SVC. We had to switch due to the Vendor lock-in and poor flexibility.

The design is the more complex part due to all use case you can address with the product. That said, the setup is simpler if you are a SAN Storage admin.

We did look at vSphere vSan.

SANsymphony is a software solution that enables storage virtualization.

We implemented SANsymphony due to its mirroring and continuous data protection features.

The installation is done independently of the hardware and even allows infrastructures in synchronous replication in active/active with different manufacturers.

The data is identical and accessible on both storage nodes. The solution also allows you to create a Disaster Recovery Site with an asynchronous and bidirectional mirror that is easier to test.

This solution allows us to have a business continuity plan for storage and as a first level of backup.

This solution allows us to have our IT production in two separate and autonomous rooms in active/active mode. The data is present in both rooms. In the event of scheduled shutdowns (works, updates, etc.) or incidents, the changeover is done manually or automatically.

The Continuous Data Protection feature and the logging of data changes allows a minimal level of data loss on incidents, human errors, or cyberattacks. This functionality makes it possible to restore the data to the moment before loss.

The synchronous mirroring is great. Storage is always available. This is the main feature of DataCore SANsymphony SDS which allows very high storage availability and better protection against environmental incidents (electrical, flooding, etc.).

Continuous data protection reduces data loss. This functionality makes it possible to restore the data to the moment before loss.

Caching and parallel I/O offer more performance. The cache is done with the RAM of the server. To add cache you just have to add RAM.

The parallelization of the IOs allows us to have much better performance with the same hardware by accelerating the processing of the IOs.

The compression and deduplication are now suitable for a production environment. Additionally, this allows us to use logical RAID for NVMe drives in ZFS clusters.

The architecture has been revised with cache and metadata disks to improve overall performance.

The graphical interface is not always very stable. In a dense infrastructure with many volumes and disks, slowness and GUI crashes can be observed. Developments are still underway to continually improve this part.

The current graphical interface is ported to a web interface and not all features are available yet.

The eagerly awaited feature is tiering between deduplicated/compressed disk pools and performance pools. This will leave the possibility of activating by virtual disk the automatic movement of blocks according to their activity.

I've been using this solution since 2008.

I have been using this solution for over a decade and it is very stable.

The solution is highly scalable by adding disks or nodes.

Technical support is awesome and very reactive.

Positive

We used Dell/EMC, VNX, and UNITY. We switched due to vendor lock-in, overpriced drives, or upgrades.

The initial setup is very simple as there are many wizards.

We handled the implementation in-house.

You get to ROI quickly by reusing material.

Users need to remember that they just need to buy what they use.

We evaluated VMware vSAN.

The support team is awesome.

We're using SANsymphnony for our primary storage in a HA environment for sensitive production data. Storage nodes are HPE servers with SSD drives in them. They serve storage to two servers blades enclosures in a Fibre Channel storage network. We have a total of 50TB in a mirror. 16 servers use this storage in a VMware vSphere environment.

This infrastructure has run without any issues since 2017 and we update it twice a year.

Before that, we had other SANsymphony infrastructure running on an old HMP MSA storage array. We migrated without any interruption.

DataCore SANsymphony brings the ability to work on almost every hardware platform and to build a storage node with high precision (disks, interfaces, protocols). We can choose what hardware we want to put in and it brings a high-performance throughput from it. The ability to build exactly what you need is a major advantage of SANsymphony over other solutions.

Hardware maintenance is easy since it is a simple server. There's no need for a storage hardware expert. On top of that, the Software-Defined Storage is easy to manage.

We used the wizard to deploy SANsymphony in a virtual environment for hyper-converged infrastructure and it is quite useful. We can deploy virtual high-available infrastructure for running tests in less than an hour.

Continuous data protection is a powerful feature that can save your data in several cases. It is good protection against ransomware.

The ability to use the RAM of the server node as a read and write cache brings a lot of performance to the storage. We can reach high IOPS from slow disks through the huge amount of cache.

The documentation repository is really useful and kept updated.

We would like to see a real "sexy" storage dashboard with capacity, usage, performance, and error tracking.

The cloud reporting interface is quite poor compared to other vendors. We are far from an HPE Infosight, for example.

Using a classic storage array constructor allows clients to have a single point of contact in case of an issue. With DataCore, we have to deal with them for the software part and with the hardware vendor for the hardware part. Sometimes, in a complex environment, we have to deal with storage array vendors, servers vendors, and software vendors and that can be exhausting.

We've been using SANsymphony for almost 10 years now. We followed all of its great evolution so far.

This solution is stable. Depending on the two rooms' interconnection, we have to deal with redundancy and maybe a witness. Losing the connection completely between the nodes can lead to a complete rebuild of a side.

The scalability is almost infinite. I cannot think of a more scalable solution.

The customer service is quick and efficient. Sometimes we have to deal with some trivial questions but that seems to be the basis of every support query right now.

We previously used an HPE 3PAR storage array. We switched to have more performance and more flexibility. The maintenance is quite easier too.

The initial setup is easy via the use of a comprehensible wizard.

We implemented the solution ourselves after a formation from the vendor.

The ROI is high as we can change or update hardware without changing our licencing. 

The main work in building a SANsymphony solution is to design and select the correct hardware parts. The setup is quite easy and the configuration is too.

The licensing is by terabyte and can be quite expensive. 

We evaluated other hardware vendors but stuck to a software-defined solution.

VMware VSAN was not mature enough for us and we did not want to use a hardware vendor solution.

You must keep in mind that you'll have to qualify the hardware you use with SANsymphony compatibility.
