Bosch and NetApp

Did you know that Bosch offers customized versions of the NetApp E-Series iSCSI Disk Arrays designed specifically for video surveillance with unsurpassed data protection and reliability.

Combine E-Series with our Video Recording Manager (VRM) to gain automatic load balancing of video streams for optimized utilization of storage space and improved retention times. For larger projects, this solution reduces hardware, power and maintenance requirements, resulting in lower costs compared to other options for video recording and storage.

Hi, we use DSA-N2E6x2-12AT and DSX-N1D6X2-12AT presently for our video surveillance. it's been operating efficiently and reliably since it's installation. Now we are experiencing growth in our IP cameras.

If we want to replace the 2TB with 4TB drives from NetApp, can we do that or does this unit doesn't support 4TB drives ? we just want to increase capacity on our existing bosch-netapp-e-series storage?

personally, i think the drive swap will work as long it is from netapp / for E-series ?

The DSA-N2E6x2-12AT and DSX-N1D6X2-12AT will support 3TB drives maximum. All drives must be replaced with 3TB drives. Use the SANtricity application from NetAPP to perform an initial configuration and RAID setup. This is all performed prior to the storage arrays even being shipped. If you have questions, please contact technical support in your region. In North America, our technical support team can be reached at 800-289-0096.

Hi, I have a question.

For instance, there are one DSA-N2E6x2-12AT linking with six DSX-N1D6X2-12AT. What will happen when one of the DSX-N1D6X2-12A goes down? Will all the data will be erased?

Bosch recommends that you setup your storage in 12 drive disk groups, one group on the base and one for each of the expansions. Thus if you have a disk group/volume failure you would only lose the data from the affected group. Bosch highly recommends the disk group is always 12 disks and on the same hardware (i.e. on the same 12-bay base or expansion unit). There are other ways to further mitigate this risk:

1) Implement RAID-6 redundancy. RAID-6 allows for two disk failures within the RAID set before any data is lost. Of course this reduces the overall net capacity of the disk group, but if your data is critical it’s a low-cost insurance policy.
2) Implement hot spare solution. You can also designate a certain number of global hot spare drives. These drives effectively sit idle until such time that you have a drive failure at which point the hot spare drive is added to the disk group and the rebuild process starts automatically. Again hot spares reduce your net capacity, but if this is a critical application it may be worth it.
3) Keep a few spare disks on site.

I have a further question.
As you recommend to form a 12 drive disk group on each expansion, does it means that the automatic configuration by BVMS is not recommended?

In our observations, BVMS just configure the disk group in a random way.

What is the point that BVMS using this approach? Is there any special design consideration?

Bosch Security Systems said...

The only thing that is random is the spare disk selection. This isn’t something BVMS does specifically, we are using an API provided by NetApp that suggests this. The creation of hot spares is done prior to the creation of the disk groups/volume where it considers the minimum number of disks for a RAID-5 stripe set (4 HDD 3x data +1 parity). To make use of all the space you may end up with some different size groups based on your RAID and spare selection.

Do you have a specific example of what you are configuring?

Our current cases:
~ 1 x E2700 (Dual Controller) + 6 Extension
~ there are around 10 number RAID-5 Group built automatically using BVMS/VRM tools. Each of RAID-5 Group forms among different Extension.
~ If any unit of 1 x E2700 (Dual Controller) + 6 Extension fail
~ then all RAID-5 Group have more than 1 number of disk fail.

In this case, there is multi-points of failure. What is the advantage of such random RAID Group among 1 x E2700 (Dual Controller) + 6 Extension

Does Bosch offer any automatic ways to re-confirm the 1 x E2700 (Dual Controller) + 6 Extension as following?
a) 1st RAID Group only in E2700 (Dual Controller)
b) 2nd RAID Group only in Extension #1
c) 3rd RAID Group only in Extension #2
d) 4th RAID Group only in Extension #3
e) 5th RAID Group only in Extension #4
r) 6th RAID Group only in Extension #5
g) 7th RAID Group only in Extension #6

One more follow up questions.
If "4th RAID Group only in Extension #3" powered off for 1 hour and then resume normal again.
During "4th RAID Group only in Extension #3" powered off, will Extension #5 and Extension #6 also offline ?

Will there be video loss (data loss) after "4th RAID Group only in Extension #3"resume 1 hour later ?

From Bosch E2700 datasheet, i cannot find CPU, RAM information for extension unit.
Am i right in saying that extension unit has no intelligent?
Extension unit is unit for cable and power connection for harddisc only. Is that right ?
