RAID 5 provides basic fault tolerance with good performance, but it cannot protect against multiple drive failures. RAID 5 with a hot spare improves fault tolerance by automatically replacing failed drives, but it still has the same limitation regarding multiple drive failures. RAID 6 offers a higher level of fault tolerance by using double parity, allowing for the simultaneous failure of up to two drives without data loss. However, it has higher write overhead and requires more drives for implementation compared to RAID 5.
Not all Cisco PoE+ switches are able to power up the UHO-PoE-10 or VSP-UHO-PoE-10 outdoor housing (F.01U.300.502, F.01U.332.052).
Bosch has introduced the UHO-PoE-10 in 2014 following the IEEE802.3-2009 standards
NetApp SANtricity Dynamic Disk Pools (DDP) technology represents a significant advancement in storage system, data protection and data management. As disk capacities continue to grow without sufficient increases in data transfer rates, traditional RAID rebuild times are getting longer, even up to several days. This slow rebuild results in much more time with degraded performance and exposure to additional disk failures.
In many cases a minimum and maximum retention time needs to be defined in a video surveillance systems due to legal requirements. While the minimum retention time defines the time period for how long video recordings need to be stored, the maximum retention time defines after which period of time the recordings have to be deleted. Thus, the minimum retention time is going to influence the amount of storage needed. The higher the minimum retention time the more storage space is required.
Importing a foreign configuration should recover a RAID configuration (in case the RAID is not corrupt) This option must be performed before creating a new VHD. This option may restore all of the video and data on the drives.
If you were asked by the Central Technical Support team to provide them with the Bios defaults picture with the Boot order of your DIVAR IP during the troubleshooting process of your device, please follow the steps from this article and find out how can you check the boot order of a DIVAR IP
This article contains 2 options describing the way you can find the Firmware version of your DSA unit, in case the Central Technical Support team is asking you about it or if you simply want to find it by yourself. Check out this article!
The purpose of this article is to assist you with the creation of mirrored drive sets in a DIVAR IP all-in-one 5000 Recording Appliance.This procedure should be performed on new appliances that have not yet been deployed.
🛈 Port Forwarding
Allows remote computers (for example, computers on the Internet) to connect to a specific computer or service within a private local-area network (LAN).
In a typical residential network, nodes obtain Internet access through a DSL or cable modem connected to a router or network address translator (NAT/NAPT). Hosts on the private network are connected to an Ethernet switch or communicate via a wireless LAN. The NAT device's external interface is configured with a public IP address. The computers behind the router, on the other hand, are invisible to hosts on the Internet as they each communicate only with a private IP address.
When configuring port forwarding, the network administrator sets aside one port number on the gateway for the exclusive use of communicating with a service in the private network, located on a specific host. External hosts must know this port number and the address of the gateway to communicate with the network-internal service. Often, the port numbers of well-known Internet services, such as port number 80 for web services (HTTP), are used in port forwarding, so that common Internet services may be implemented on hosts within private networks.
