Hanwha Wisenet SSM high availability solution

Evidian SafeKit

How to implement Hanwha Wisenet SSM high availability with SafeKit?

Why Wisenet SSM application is critical?

Hanwha CCTV products for video surveillance (network cameras, encoders, Digital Video Recorders and Network Video Recorders) are managed through a single application, named Hanwha Wisenet SSM.

The Wisenet SSM application is critical because,

  • numerous users can administer video surveillance products installed across multiple sites,
  • users monitor maps, live images, playbacks and health checks for each device,
  • critical events are displayed to allow the immediate reaction of users.

The operators relying on the Wisenet SSM application must react immediately to the slightest incident. The idea of an IT failure compromising the video surveillance and the operators’ view is totally unthinkable.

For 24x7 high availability of Wisenet SSM, download a free trial of SafeKit and the SSM module

SafeKit is a simple and economical high availability software. SafeKit is installed on two standard Windows PCs or servers (physical or virtual). Without changing the Wisenet SSM application, a mirror SSM module implements real-time replication of Wisenet SSM data over the network, automatic restart of the application in case of failure and failover of the virtual IP address.

Testimonial on SafeKit for high availability of Wisenet SSM

Tommy Park, CEO, WithNCompany, South Korea:

“WithNCompany is a reseller of Evidian SafeKit in South Korea. WithNCompany has deployed many SafeKit high availability solutions with the Hanwha Wisenet SSM application. SafeKit is appreciated because the product is easy to install and very quickly deployed. The Wisenet SSM application does not need to be modified to run in the high availability mode. The Wisenet SSM application can be installed on the default C: drive and there is no need to configure a separate disk volume. SafeKit is able to make real-time replication of SSM folders inside the C: drive. Moreover, for cost saving, SafeKit can be installed on 2 Windows PCs instead of 2 servers.”

SafeKit High Availability Differentiators against Competition

Evidian SafeKit mirror cluster with real-time file replication and failover

3 products in 1 >

3 products in 1

Like  SafeKit high availability software on Windows and Linux saves on 1/ costly external shared or replicated storage, 2/ load balancing boxes, 3/ enterprise editions of OS and databases

Like  SafeKit includes all clustering features: synchronous real-time file replication, monitoring of server / network / software failures, automatic application restart, virtual IP address switched in case of failure to reroute clients

Very simple configuration >

Simple configuration with a web console

Like   The cluster configuration is very simple and made by means of application modules. New services and new replicated directories can be added to an existing application module to complete a high availability solution

Like   All the configuration of clusters is made using a simple centralized web administration console

Like   There is no domain controller or active directory to configure as with Microsoft cluster

Synchronous replication >

Synchronous replication

Like  The real-time replication is synchronous with no data loss on failure

Dislike  This is not the case with asynchronous replication

Fully automated failback procedure >

Automatic failback

Like  After a failure when a server reboots, the replication failback procedure is fully automatic and the failed server reintegrates the cluster without stopping the application on the only remaining server

Dislike  This is not the case with most replication solutions particularly with replication at the database level. Manual operations are required for resynchronizing a failed server. The application may even be stopped on the only remaining server during the resynchonization of the failed server

Replication of any type of data >

Any replicated data

Like  The replication is working for databases but also for any files which shall be replicated

Dislike  This not the case for replication at the database level

File replication vs disk replication >

File replication vs disk replication

Like  The replication is based on file directories that can be located anywhere (even in the system disk)

Disike  This is not the case with disk replication where special application configuration must be made to put the application data in a special disk

File replication vs shared disk >

File replication vs shared disk

Like  The servers can be put in two remote sites

Dislike  This is not the case with shared disk solutions

Remote sites and virtual IP address >

Remote sites

Like  All SafeKit clustering features are working for 2 servers in remote sites. Replication requires an extended LAN type network (latency = performance of synchronous replication, bandwidth = performance of resynchronization after failure).

Like  If both servers are connected to the same IP network through an extended LAN between two remote sites, the virtual IP address of SafeKit is working with rerouting at level 2

Like  If both servers are connected to two different IP networks between two remote sites, the virtual IP address can be configured at the level of a load balancer with the "healh check" of SafeKit.

Quorum >

Quorum

Like  The solution works with only 2 servers and for the quorum (network isolation between both sites), a simple split brain checker to a router is offered to support a single execution of the critical application

Like  This is not the case for most clustering solutions where a 3rd server is required for the quorum

Active/active cluster >

Active active mirror cluster

Like  The secondary server is not dedicated to the restart of the primary server. The cluster can be active-active by running 2 different mirror modules

Dislike  This is not the case with a fault-tolerant system where the secondary is dedicated to the execution of the same application synchronized at the instruction level

Uniform high availability solution >

Uniform high availability solution

Like  SafeKit implements a mirror cluster with replication and failover. But it imlements also a farm cluster with load balancing and failover.

Like  Thus a N-tiers architecture can be made highly available and load balanced with the same solution on Windows and Linux (same installation, configuration, administration with the SafeKit console or with the command line interface). This is unique on the market

Dislike  This is not the case with an architecture mixing different technologies for load balancing, replication and failover

RTO / RPO >

Simple configuration with a web console

Like  SafeKit implements quick application restart in case of failure: around 1 mn or less (see RTO/RPO here)

Dislike  Quick application restart is not ensured with full virtual machines replication. In case of hypervisor failure, a full VM must be rebooted on a new hypervisor with a recovery time depending on the OS reboot as with VMware HA or Hyper-V cluster

Evidian SafeKit farm cluster with load balancing and failover

No load balancer or dedicated proxy servers or special multicast Ethernet address >

No load balancer or dedicated proxy servers

Like   The solution does not require load balancers or dedicated proxy servers above the farm for imlementing load balancing. SafeKit is installed directly on the application servers in the farm. The load balancing is based on a standard virtual IP address/Ethernet MAC address and is working with physical servers or virtual machines on Windows and Linux without special network configuration

Dislike  This is not the case with network load balancers

Dislike  This is not the case with dedicated proxies on Linux

Dislike  This is not the case with a specific multicast Ethernet address on Windows

All clustering features >

All clustering features

Like  The solution includes all clustering features: virtual IP address, load balancing on client IP address or on sessions, monitoring of server / network / software failures, automatic application restart with a quick revovery time and a replication option with a mirror module

Dislike  This is not the case with other load balancing solutions. They are able to make load balancing but they do not include a full clustering solution with restart scripts and automatic application restart in case of failure. They do not offer a replication option

Like   The cluster configuration is very simple and made by means of application modules. There is no domain controller or active directory to configure on Windows. The solution works on Windows and Linux

Remote sites and virtual IP address >

Remote sites

Like   If servers are connected to the same IP network through an extended LAN between remote sites, the virtual IP address of SafeKit is working with load balancing at level 2

Like   If servers are connected to different IP networks between remote sites, the virtual IP address can be configured at the level of a load balancer with the help of the SafeKit health check. Thus you can implement load balancing but also all the clustering features of SafeKit, in particular monitoring and automatic recovery of the critical application on application servers

Uniform high availability solution >

Uniform high availability solution

Like  SafeKit imlements a farm cluster with load balancing and failover. But it implements also a mirror cluster with replication and failover.

Like  Thus a N-tiers architecture can be made highly available and load balanced with the same solution on Windows and Linux (same installation, configuration, administration with the SafeKit console or with the command line interface). This is unique on the market

Dislike  This is not the case with an architecture mixing different technologies for load balancing, replication and failover

Software clustering vs hardware clustering >

A software cluster with SafeKit installed on two servers

Like  A simple software cluster with the SafeKit package just installed on two servers

Hardware clustering with external shared storage

Dislike  Complex hardware clustering with external storage or network load balancers

Shared nothing vs a shared disk cluster >

SafeKit shared-nothing cluster: easy to deploy even in remote sites

Like  SafeKit is a shared-nothing cluster: easy to deploy even in remote sites

Shared disk cluster: complex to deploy

Dislike  A shared disk cluster is complex to deploy

Application High Availability vs Full Virtual Machine High Availability >

SafeKit application high availability supports hardware failure, software failure, human errors

Like  Application HA supports hardware failure and software failure with a quick recovery time (RTO around 1 mn or less).
Smooth upgrade of application and OS possible server by server (version N and N+1 can coexist)

Virtual machines high availability supports only hardware failure with an recovery time depending on the OS reboot

Dislike  Full virtual machines HA supports only hardware failure with a VM reboot and a recovery time depending on the OS reboot.
Smooth upgrade not possible

High availability vs fault tolerance >

SafeKit high availability vs fault-tolerance

Like  No dedicated server with SafeKit. Each server can be the failover server of the other one.
Software failure with restart in another OS environment.
Smooth upgrade of application and OS possible server by server (version N and N+1 can coexist)

Fault tolerance system

Dislike  Secondary server dedicated to the execution of the same application synchronized at the instruction level.
Software exception on both servers at the same time.
Smooth upgrade not possible

Synchronous replication vs asynchronous replication >

SafeKit synchronous replication with no data in case of failure

Like  SafeKit implements real-time synchronous replication with no data loss in case of failure

Asynchronous replication with data loss on failure

Dislike  With asynchronous replication, there is data loss on failure

Byte-level file replication vs block-level disk replication >

SafeKit cluster with byte-level file replication: simply replicates directories even in the system disk

Like  SafeKit implements real-time byte-level file replication and is simply configured with application directories to replicate even in the system disk

Cluster with block-level disk replication: complex and require to put application data in a special disk

Dislike  Block-level disk replication is complex to configure and requires to put application data in a special disk

Heartbeat, failover and quorum to avoid 2 master nodes >

Simple quorum in a SafeKit cluster with a split brain checker configured on a router

Like  To avoid 2 masters, SafeKit proposes a simple split brain checker configured on a router

Complex quorum in other clusters: third machine, special quorum disk, remote hardware reset

Dislike  To avoid 2 masters, other clusters require a complex configuration with a third machine, a special quorum disk, a special interconnect

Virtual IP address
primary/secondary, network load balancing, failover >

No special network configuration in a SafeKit cluster

Like  No dedicated proxy servers and no special network configuration are required in a SafeKit cluster for virtual IP addresses

Special network configuration in other clusters

Dislike  Special network configuration is required in other clusters for virtual IP addresses. Note that SafeKit offers a health check adapted to load balancers
