5. Main operational tasks of VRM
Bosch Video Management System
Main operational tasks of VRM
VRM Server is an intelligent storage management service for recording and playback:
1. Manages the storage utilisation and assigns blocks to the cameras for their recordings:
Video data stores directly to iSCSI storage: IP camera  iSCSI storage
2. Answers playback location request from Operator Client (Where is the recording from yesterday ?)
Operator Client  VRM Server (recording index database)  Operator Client
3. Provides replay Video Data from iSCSI to Operator Client
a) default setting is via VRM server
iSCSI Storage  VRM Server  Operator Client
b) VRM server is not involved in providing video data
iSCSI Storage  Operator Client
VRM is not involved: Live video request directly from IP camera  Operator Client

6. Main operational tasks of VRM
Bosch Video Management System
Main operational tasks of VRM
Let’s focus on the first point:
Manages the storage utilisation and assigns blocks to the cameras for their recordings:
Uses iSCSI technology, this allows direct camera to storage recording
Has a built in learning algorithm that manages storage allocation, consumption, and distribution
Manages simultaneous centralized and distributed storage scenarios
Has built-in failover and mechanisms that allows the system (cameras & storage) to function without server supervision for up to 7 days

Basic VRM Functionality: LUNs & Blocks
The iSCSI Storage target is divided into LUNs (max. 2TB each)
LUNs of all iSCSI targets are formatted into 1 GB blocks (spans)
Blocks are distributed to devices (cameras)
Each device (camera) manages its own storage Max. 512 blocks (each 1GB) per recording stream
Example Address of one Block:
IP-Address of Target / LUN / Block
/ 0 / 15
Several 1 GB Blocks are assigned to each Camera. Camera starts recording and consumes blocks.

15. VRM storage pool configuration
Bosch Video Management System
VRM storage pool configuration
Logically groups devices and iSCSI storage boxes together.
Cameras are only allow to record to the iSCSI storage boxes assigned within its own storage pool.
VRM can manage up to 120 storage pools.
Each storage pool manages its own recording mode and load balancing.
iSCSI Storage Pool improves the load balancing of iSCSI write performance
120 storage pools per VRM as VRM can manage 120 iSCSI targets. Each pool is assigned one target.
E.g. 12 pools for 1 VRM:
Possible to have 10 iSCSI target in each of the 12 pools with respective cameras/encoders
Or may 5 iSCSI target in Pool 0, 15 iSCSI target in Pool 1, etc. As long as total number of iSCSI targets do not exceed 120.

16. VRM Storage Pool Configuration
Bosch Video Management System
VRM Storage Pool Configuration
Recording preferences mode:
Automatic
Load balancing is configured automatically
Failover
Recordings are saved only to primary target.
If it is not possible to save to primary target, the recording will be saved to the target entered under secondary target.
Failover:
A failure situation is reached if the primary target does not provide storage blocks due to whatever reason:
system down, network error, no capacity left.
You can leave the second list empty. In this case no failover is possible but the number of required iSCSI sessions is reduced and no disk space on secondary target is allocated. This reduces system overhead and extends the system retention time.

17. VRM Storage Pool configuration: storage utilisation modes for Cameras
Bosch Video Management System
VRM Storage Pool configuration: storage utilisation modes for Cameras
Automatic Storage utilisation
VRM performs always 2 major steps when adding cameras to a pool with “recording preference mode = automatic”
First Step:
Assign every camera 2 iSCSI targets, but not more (Prerequisite: more than one available)
Second Step:
Assign free blocks (to be recorded) of that max. 2 iSCSI targets to the cameras
Automatic mode on Pool level 1 2 3 4
Target: 1 & 2
Automatic mode is recommended and
used in the majority of deployments!
Each camera gets blocks from max. 2 out of x iSCSI Targets
Target: 3 & 4
Load balancing across all arrays
No manual configuration required
Recommended for single array or single storage location
VRM ensures that maximum bitrate limits of iSCSI targets are not exceeded !

19. VRM Storage Pool Configuration: Storage utilisation
Bosch Video Management System
VRM Storage Pool Configuration: Storage utilisation
Automatic Storage utilisation
Why to use always more than 1 iSCSI target…?
In case an iSCSI target fails:
Encoder skips the Blocks of that iSCSI target and writes to the other one from its block list
If failure of iSCSI target persists, VRM will assign a new block list to encoder
When iSCSI target comes back after failure:
Encoder always tries previous skipped Blocks when mounting a block
Encoder starts using that target again
Bosch USP
This feature is always implementable by design.
No extra license cost !
Just choose 2x iSCSI HW when possible.

22. VRM Storage Pool Configuration: VRM downtime
Bosch Video Management System
VRM Storage Pool Configuration: VRM downtime
Block reservation for downtime (VRM downtime in days):
1 – 7 days
4 days is the default value
Value specifies how long cameras continue to record
without being assigned new blocks
E.g. 4 means the cameras will record approximately
4 days even if the VRM is down
For this the VRM reserves a 4-day ration of recording blocks for the camera
In this case, 4 days are considered the maximum possible downtime of the VRM
The number of blocks reserved for a camera is calculated from the bitrate that is specified for that camera
Higher bitrate means bigger reservation on the storage system – empty blocks are bound in the camera’s span list
Normal assumption is, that VRM downtime is less than the minimum retention time. If min retention time < downtime, then allocated number of required storage blocks based on min retention time.
VRM downtime is a max downtime.
No guarantee that complete downtime can be covered by given blocks to units if VRM is down: Related to high bit rates from e.g. UHD cameras, as 128 GB blocks probably are not enough to cover a long VRM downtime. Read the comment from Gerard below for some background on the topic and on the current planning's in VRM R&D.
Reducing the VRM downtime value reduces storage overhead as well.
Comment from Gerard Chua related to: No guarantee that complete downtime can be covered by given blocks to units if VRM is down:
This was put in my previous slides because I discovered that in current VRM versions 3.0 – 3.5, the maximum default spans list VRM will issue to devices is 128. In some scenarios, especially for high resolution & bitrate cameras, even on default 4 days downtime setting, the cameras needed more than 128 blocks to meet downtime setting.
For lower bitrate cameras, this is may not be an issue if the number of blocks required to maintain its downtime setting is less than 128 blocks. The maximum span list can be adjusted by adding a registry key in VRM server to raise the maximum to 512 (in increments of 16 from ).
I have a Jira ticket (TSAP-2607) confirming this with VRM developers, which they acknowledge and will revise the default maximum allocated spanlist from 128 to 512 in VRM 3.60 (tentative).
I have indicated in the ticket that this information should be updated in the knowledge base, especially in KB 6764, to acknowledge the potential maximum span list issue with current VRM versions and indicate that manual setting of the registry as the workaround as we have always been preaching that the VRM downtime is guaranteed!
Add-on PG: Currently in BVMS 6.5 we have VRM 3.55, so let’s see how it will change in BVMS 7.x.

23. VRM Storage Pool configuration: Sanity check
Bosch Video Management System
VRM Storage Pool configuration: Sanity check
Sanity check period (days):
1 – 7 days
2 days is the default value
Sanity check determines how much data a camera has produced in the last days (bandwidth)
The camera’s emergency ration of blocks for downtime is calculated from this determination of bandwidth
Number of blocks and allocation to iSCSI targets are readjusted

Bosch Video Management System
Use-case example: Failover VRM (VRM Redundancy)
Example: The requirements in a project are:
All servers must have redundant backup servers
Playback must continue to work if VRM server fails
No degraded functionality for playback is acceptable
To solve above requirements one option would be to install another VRM server and use it in “failover” mode:
This would fulfill the requirements since the failover VRM always synchronizes with the Master VRM and will take over once it detects that Master VRM is not reachable.
Full functionality will remain.

40. Use-case example: Dual recording with a secondary VRM
Bosch Video Management System
Use-case example: Dual recording with a secondary VRM
The requirements in a project are:
A certain number of cameras in the installation needs to record 2 different streams to 2 different storage locations
In addition to normal (primary) recording on the storage in building 1, plus a second recording on the storage in building 2, is required for disaster mitigation scenarios
The recording settings of the secondary recording must be configurable independently of recording settings for the primary recording (retention time & stream-quality settings)
To solve above requirements one option would be to install a secondary VRM server and a secondary Storage:
This would solve the recording demand of parallel recording
This would solve the independent configuration for the second recording

43. BVMS & VRM: An outstanding recoding solution on the market!
Bosch Video Management System
VRM – Summary: Benefits
Fewer hardware components makes setup easier (TCO & footprint !)
Easy to add storage without requiring a complex upgrade procedure
VRM make the decision where the Intelligent cameras will record data
Every camera/encoder adds additional computational power, as it does the recording independently after VRM assigned Storage Blocks to it.
Flexible storage utilization modes: Automatic mode and pre-assigned failover mode
Virtualization/redundancy is not implemented on the physical hardware (server/storage)
N+1 Server HW normally not required, but standby Failover VRM available as optional feature
Dual-recording VRM as optional feature: for avoiding data loss from site disaster (fire, etc. ) Second camera stream is recorded at a different site from that of the first stream.
BVMS & VRM: An outstanding recoding solution on the market!
PG: The whole slide is taken from Sales presentation: VRM against competitor NVR comparison scenario. So all bullet point need to be seen in comparison to a other vendor NVR solution.

Additional Information
Detailed information about VRM:
Block allocation / replenishment
VRM monitor
SNMP
PG: What is the purpose of this Additional Information section in all slide sets ?
All of this slides are not relevant for the Exam
These slides are optional to present and not mandatory due to any of this reasons:
+ skipped due to time saving reasons. The new BVMS Expert (3days) approach requires to focus on main topics and does not allow to give too much information.
The 3 days time restriction is already tough to achieve considering the wide range of features and functionality BVMS has nowadays.
+ additional side information
+ very detailed information and good for self reading
+ not in the main scope of learning
+ copied from another .ppt: Not good enough to include them in the main presentation and not bad enough to delete them 

45. Bosch iSCSI storage use
Bosch Video Management System
Bosch iSCSI storage use
Bosch storage boxes utilize Microsoft iSCSI Software Target.
1 iSCSI target per storage box (IP address)
Storage box virtualizes the disk spaces into virtual hard disks (Virtual Drives), which are assigned a logical unit number (LUN) on the iSCSI target.
The maximum size for a virtual hard disk is 208,8960 MB (2,040 GB or TB (~2 TB) ) for master boot record (MBR) disks.
Formatting the LUNs organizes it into blocks of 1 GB each.

46. Block allocation & distribution
Bosch Video Management System
Block allocation & distribution
Assign camera(s) to VRM only when iSCSI storage is already available (formatted and ready).
1GB blocks are issued to each camera.
The number of blocks issued depends on the VRM pool’s block reservation for downtime.
For initial allocation:
Each camera is assigned an initial number of 5 blocks first.
Based on the encoder profile settings (bandwidth) the number of blocks required are calculated.
With no bandwidth history for each camera, VRM will take a default maximum bandwidth of 2500 Kbps for each camera.

47. Block replenishment Bosch Video Management System
Block replenishment
Block replenishment is done for each device in the same order as they exceed their storage:
The device that runs out of storage first will get one more block as soon as possible.
The next device that runs out of storage will get one more block.
And so on…
The time when a device runs out of blocks is predicted from the length of time it has needed to fill blocks, averaged over the last 7 days:
If historical data is not available it gets the time-per-block from the encoder profile settings.
If that fails, it assumes a default time-per-block of 6 hours.

49. License requirement Bosch Video Management System
License requirement
No separate VRM license is required for VRM servers managed by BVMS Management Server.
BVMS Channel license is required on BVMS Management Server for cameras, encoders and decoders.
VRM Server must always be connected to BVMS Management Server to renew its license:
VRM will renew its license every hour from BVMS MS.
If it cannot update the license within 24 hours of the last successful update, the license will expire and VRM will stop functioning.
