Water Resources SCADA Network Consulting and Support Services I RFP # 23-124 <br />Req Description Support XV Solutions Response <br />3—g Static/Dynamic Y XV Solutions has experience managing both Dynamic IP addresses, <br />IP Address which are typically used for mobile devices and workstations, and <br />Management static IP addresses, which are usually required for servers. <br />Dynamic IP addresses are managed with a DHCP Server. Windows <br />Server operating systems, such as Windows 2008, Windows 2019, <br />and Windows 2022 come with a built-in DHCP Server service that can <br />be turned on and configured to dynamically assign IP addresses to <br />devices connected to the network. Some appliances, like the <br />Netgear SRX5308 also come with a built-in DHCP server that can be <br />used for this purpose. <br />Critical servers, like SCADA servers, SMTP/Email servers, Microsoft <br />SharePoint, and other application servers require a static IP address. <br />Static IP addresses can be reserved in a DHCP server. <br />3—h <br />RAID Y RAID (Redundant Array of Independent Disks) is a method of <br />Configuration grouping multiple hard -drives, so that the OS views multiple drives <br />Support as one logical drive. There are several advantages to RAID <br />configurations, such as increased read/write performance and <br />redundancy. XV Solutions has expertise in creating various types of <br />RAID configurations, and has configured RAID-5 for the Water <br />Resources Division. <br />3—i <br />VPN Support Y Knowledge in configuring Netgear VPN Router and Cisco ASA/NGFW <br />firewalls to allow external systems VPN access to internal network. <br />3—j <br />Network Y Yes, we have experienced implementing redundant VPNs using <br />Redundancy CISCO NGFW devices, with two identical devices that have a primary <br />online device and a secondary standby device, so that we can <br />maintain an HA (highly availability) for the firewall/vpn devices and <br />reduce remote access outages. <br />3-k <br />Reporting Y Yes, monthly reports can be easily prepared and delivered via email, <br />posted on the SharePoint server, added to a file server, or any other <br />method that is convenient or desired. <br />3-1 <br />MDS Radio Y MDS Radios can receive and send transmission to SCADA PLCs. The <br />Support SCADA servers need to be connected to the same Ethernet network <br />where the MDS Radio is dropping network packets; so that the <br />SCADA server can process the packets received and also send out <br />changes to PLCs. XV Solutions is experienced with networking <br />requirements for MDS Radios and verifying that they are working <br />properly for SCADA operations. <br />3-m <br />Server Software Y XV Solutions has experience in managing and applying patches via <br />Maintenance several methods: (1) Command line updates for Linux distributions. <br />(2) Manually deploying Windows Updates via the Desktop.
