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.

I'm working on a SanSymphony infrastructure. I use it for my company, and this is also what we install for our clients.

All of the clients have to do maintenance operations during business hours, and they have to schedule it never to disturb their users. Thanks to San Symphony, they can do whatever they want, whenever they want.

I really like to dissociate virtual volumes from any virtual machines. It allows you to manage granularly the storage of your virtual machines. I separated VMs and files on different volumes in my case

Before using San Symphony, I had to work late to improve my IT infrastructure. Now, I can do it at any time of day.

We also won on availability. When one of the servers crashes, there is no effect on our production. It rarely happens; however, we would have been out of production with our previous infrastructure.

We do things differently now. We use our backup solution to backup storage rather than to backup machines, and I find it has less impact on the performance of our virtual infrastructure.

I really like the Rollback option, which is like a video of my storage. Administrators benefit from being able to return to a single previous point as precisely as they want.

I also find that the support team is a real quality of the Datacore SanSymphony environment. Opening a case is very simple, and the answers of support are always detailed with precision.

The dashboard is very intuitive, and there are many counters to diagnose what happens during a short period (like when a backup is in progress).

The product can be improved by making better filters to search event logs. When everybody shows the last event at the top of their board, San Symphony does it at the bottom, and sometimes, we don't see an alert that needs to be checked.

The service is still available every day and at every time of the day, yet only in English. For customers or technicians who don't speak and understand English, it would be great to have other language support, all the more so given the number of countries in which SanSymphony is used.

I've used the solution for three years.

I've used the solution for six months.

I have never heard one of my customers complain about the stability of San Symphony.

I knew about San Symphony six months ago, and this is the second update that I can see. Developers are working in line with what customers are asking for.

Every time I needed support, they gave me a solution.

Positive

I did not use a different solution previously.

The initial setup is very simple. There are documents to send to Datacore Support, and these were a little bit difficult to fill.

We are the vendor team, so for our use, we did it ourselves

The ROI is difficult to estimate.

I did not evaluate other options; my company already has a partnership with Datacore.

I am an infrastructure engineer for a partner and 95% of the infrastructure that I recommend and/or install and maintain for my clients are based on the triptych: SANsymphony/vSphere/Veeam.

I have often succeeded in convincing clients to add security to their storage by replacing an old single-site infrastructure while providing a Business Continuity Plan solution.

Of all the customers where I installed the DataCore solution, only one decided not to keep it; however, it was for reasons of political strategy following a change of CIO.

The main feedback from my customers concerns the performance of the DataCore SANsymphony - thanks to the embedded Auto-tiering technology which avoids users purchasing an expensive physical storage when the majority of their data is no longer active beyond a few weeks and do not need to be stored.

They have a quality support team, which offers assistance in French when necessary (particularly for Public Service customers who do not speak English fluently). They respond very quickly to engage with any serious problems encountered.

Auto-tiering to obtain performance at a lower cost without the customer having to purchase ultra-fast storage is great. The ease of increasing the volume of storage without interruption of services and without impact on users is helpful. At the same time, they are leaving the choice to adapt storage technology according to a user’s needs. The abstraction of the hardware layer, especially when it is necessary to change the brand and/or model of equipment during infrastructure renewal is good. The possibility of installing the solution in HCI mode for small structures makes it possible to address large accounts as well as small businesses.

I would like to see SMPA (Shared Multi-Port Array) technology developed with the aim of allowing a configuration identical to other storage arrays: instead of having a single storage controller per site, competing arrays all have 2 controllers for redundancy and securing data access (3Par, Unity, MSA, etc.) It would be necessary to automate the operation of two nodes managing the same storage per site and no longer be obliged to manage it by a system of scripts which must be revalidated each time the product is updated.

I've used the solution since 2002.

There will always be problems with a software solution; the responsiveness of the support and developers allows them to be corrected very quickly, and even sometimes individually, in relation to a specific problem for a particular client.

In the majority of cases, the failures that I encountered with my clients had their origin in one of the other components of the infrastructure (hypervisors or switches).

Scalability is one of the many advantages, as the evolution of the solution is simple and does not interrupt services.

Of all the software that I use in my job, it is the one that has the best support. When the problem is not with DataCore, they often help me and sometimes even directly provide the solution to modify the settings on the other components of the infrastructure causing the problem.

Positive

Sometimes some customers use other storage solutions, but whenever possible; I advise them to switch to DataCore

The initial training and accompanying certification made it simple and practical to implement the solution.

I am not able to answer for my clients; however, as long as they do not move to another solution, their ROI should correspond to their expectations.

Most of the time, it is easy to prove that in the long term, this solution is the most advantageous for the client cost-wise; both in terms of equipment renewal and ease of handling.

When I started proposing and installing, I only knew about traditional infrastructures that did not provide security at the data level.

My professional career will end soon; however, as long as the product is available, I will continue to recommend it to more and more new customers and maintain it among those who continue to use it.

• We use DataCore SANsymphony as our primary storage solution replicated on two hosts since October 2012. In July 2018, we dispatched them to the two server rooms.
• Each DataCore node consists of a server and two storage bays connected in SAS.
• We use this SAN to store our VMware datastore (300 virtual machines) for our 10 ESXi servers.
• Each server is connected to storage via two fiber channel links 8Gbps.

Previously, we had some Windows and Linux servers with direct-attached storage. Our server's farm increases faster than our server room. So, we thought about virtualizing our applications. We chose to use VMware ESXi and DataCore SANsymphony to create our new infrastructure and then began to deploy our infrastructure on one server room. Then in 2018, we chose to dispatch them for more security in two server rooms.

• The better features are the synchronous replication and the management console.
• The synchronous replication gives us the ability to make business continuity planning.
• I like the management console which is very easy to use.

DataCore is currently working with Veeam software for a better integration; this is my only desired missing feature today.

With this feature, Veeam do a snapshot on Virtual Machine, then snapshot the storage.
When storage snapshot is done, Veeam remove the Virtual Machine snapshot to avoid long period snapshot.
With a VMware snapshot period smaller, consolidate will be faster and production will be less impacted.
Then Veeam save VMs directly from storage snapshot without VM performance impact.

When Backup Job is done, veeam ask to Datacore to remove Storage snapshot without any VM interruption or impact performance.

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.

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.
