About the Cisco ENCS 5400-W and ENCS 5400 Series

The Cisco Enterprise Network Compute Series (ENCS) is used to host the Cisco Enterprise Network Functions Virtualization (NFV) solution. ENCS is also used to deploy the Cisco NFV Infrastructure Software (NFVIS), and Cisco and third party VNFs on Cisco Enterprise NFV.

For more information on Cisco NFVIS, see Chapter 8, “Cisco vWAAS on Cisco ENCS 5400-W Series” .

Table 7-1 describes how the ENCS 5400 Series and the ENCS 5400-W Series (used with vWAAS) are used with Enterprise NFV. For more information on the Cisco ENCS 5400-W series, see the Cisco 5400 Enterprise Network Compute System Data Sheet.

Table 7-1 Cisco ENCS 5400 Series and ENCS 5400-W Series

Cisco ENCS Series	Description
ENCS 5400 Series	The Cisco ENCS 5400 Series—ENCS 5406, 5408, and 5412—is a line of compute appliances designed for the Cisco SD-Branch and Enterprise NFV solution.
ENCS 5400-W Series	The ENCS 5400-W Series—ENCS 5406-W, 5408-W, and 5412-W—is an x86 hybrid platform is designed for the Cisco Enterprise NFV solution, for branch deployment and for hosting WAAS applications. These high-performance units achieves this goal by providing the infrastructure to deploy virtualized network functions while at the same time acting as a server that addresses processing, workload, and storage challenges. Note vWAAS is designed to run in appliance mode or as a Virtualized Network Function (VNF) in three Cisco ENCS 5400-W series models—ENCS 5406-W, ENCS 5408-W, ENCS 5412-W—and three Cisco PIDs—ENCS 5406-K9, ENCS 5408-K9, ENCS 5412-K9.

Caution vWAAS is designed to run in appliance mode or as a Virtualized Network Function (VNF) in three Cisco ENCS 5400-W series models (ENCS 5406-W, ENCS 5408-W, and ENCS 5412-W) and three Cisco PIDs (ENCS 5406-K9, ENCS 5408-K9, and ENCS 5412-K9).

For guaranteed performance, the ENCS 5400 Series, UCS-C Series, UCS-E Series, and ISR configurations listed in the WAAS Sizing Guides and specifically noted in WAAS and vWAAS user guides and WAAS Release Notes are the only devices we recommend for use with vWAAS. Although vWAAS models may be able to operate with other Cisco or third-party hardware, successful performance and scale for those configurations is not guaranteed.

vWAAS as VM on Cisco ENCS 5400-W Series

For vWAAS with Cisco Enterprise NFVIS on ENCS, vWAAS operates as a VM to provide WAN and application optimization, and, optionally, application optimization with Akamai Connect.

vWAAS with Cisco Enterprise NFVIS runs on Cisco ENCS 5400-W series, the Cisco x86 hardware platform for branch deployment, for routing and hosted applications.

Table 7-2 shows supported vWAAS models for Cisco ENCS 5406-W, 5408-W, and 5412-W.

Registering vWAAS on ENCS 5400-W

Before you begin, verify the following:

• The disk is already mounted.
• Gigabit Ethernet port 0/0 can be used for vWAAS management or data.
• Gigabit Ethernet port 0/1 can be used for vWAAS management or data.
• The existing LAN-net and SR-IOV will be used.

To register vWAAS on ENCS, follow these steps:

Step 1 Power on the ENCS device.

The vWAAS automatically starts up when the ENCS device is powered on.

Step 2 Using an Ethernet cable, connect your laptop to the MGMT port of the ENCS device.

Step 3 Verify that the WiFi is disabled on your laptop.

Step 4 Perform the following steps on a MAC system:

• Navigate to Preferences > Network > Thunderbolt.
• From the Configure IPv4 drop-down list, choose Manually.
• In the IP Address field, enter an IP address, for example, 192.168.1.5.
• In the Subnet Mask field, enter 255.255.255.0.
• Open the terminal and use SSH to connect to the device (192.168.1.1).

Use admin for login and password credentials.

Step 5 Run the shell script (mfg.sh), which registers, installs, and checks the status of the vWAAS instance.

Step 6 Exit.

Deploying vWAAS on ENCS 5400-W

To deploy vWAAS on NFVIS on ENCS, follow these steps:

Step 1 Perform the steps shown in Registering vWAAS on ENCS 5400-W.

Progress: ############ 100%
Installation is completed!!!

Step 8 Registration and installation are complete.

Step 9 Exit.

Registering vWAAS on ENCS 5400-W with the Central Manager

You must register the vWAAS instance and/or the WAAS appliance running in accelerator mode with the WAAS Central Manager.

To register vWAAS on NFVIS on ENCS with the Central Manager, these steps:

Step 1 The Central Manager IP address is 10.78.99.142.

At the vWAAS instance or WAAS appliance that you want to register, enter the following Central Manager IP address information:

Step 2 At the vWAAS instance or WAAS appliance that you want to register, enable the Centralized Management System (CMS) service:

Step 3 In the Central Manager, navigate to Devices > All Devices.

• The WAAS appliance will be displayed in the Device Type column as OE-ENCS.

Step 4 Exit.

Migrating Equipment from No RAID and 1 SSD to RAID-1 and 2 SSDs

Note The RAID-1 option is available for vWAAS for WAAS Version 6.4.1a and later.

Before You Begin

• To enable RAID-1 virtual disk on ENCS, refer to Mixing Drives Types in RAID Groups for hard drive compatibility and best practice for performance. Before creating virtual disk, both drives must be in Unconfigured Good state. If drive is in other status, use the CIMC Web GUI or CLI and do the following:

If disk is in JBOD state:

a. Navigate to Storage tab > Physical Drive Info tab.

b. In the Actions area, choose Set State as Unconfigured Good.

c. Confirm that disk is in Unconfigured Good state.

If disk is in Foreign Config state:

a. Navigate to Storage tab > Controller Info tab.

b. In the Actions area, choose Clear Foreign Config.

c. In the Actions area, choose Unconfigured Good.

d. Confirm that disk is in Unconfigured Good state.

To create the virtual disk, follow these steps:

Step 1 Log in to the CIMC console.

Step 2 In the CIMC console left pane, click the Storage tab.

Step 3 In the CIMC console middle pane, click the Controller Info tab.

Step 4 In the Action area, click Create Virtual Drive from Unused Physical Drives.\

The Create Virtual Drive from Unused Physical Drives Wait dialog box is displayed.

Step 5 In the Create Virtual Drive from Unused Physical Drives dialog box, choose the following:

a. At the RAID Level drop-down box, choose 1.

b. In the Create Drive Groups area:

Select physical drives for your system from the Physical Drives pane and click >> to add these to the Drive Groups pane.

c. In the Virtual Drive Properties area:

• The Virtual Drive Name field displays the automatically assigned name.
• At the Strip Size drop-down list, select the strip size (default is 64k).
• At the Write Policy drop-down list, select the Write policy (default is Write Through)
• At the Access Policy drop-down list, select the Access policy (default is Read Write).
• At the Read Policy drop-down list, select the Read policy (default is No Read Ahead).
• At the Cache Policy drop-down list, select the Cache policy (default is Direct IO)
• At the Disk Cache Policy drop-down list, select the Disk Cache policy (default is Unchanged).
• The value for the Size drop-down list automatically filled.

Step 6 Click Create Virtual Drive.

Migrating Equipment from RAID-1 and 2 SSDs to No RAID and 1 SSD

Note The RAID-1 option is available for vWAAS for WAAS Version 6.4.1a and later.

Before You Begin

• You must wait for the disk to be completely shut down before you physically remove the disk from the WAE. When the RAID removal process is complete, WAAS generates a disk failure alarm and trap. In addition, a syslog error message is logged.
• If the removal event occurs while the RAID array is in the rebuild process, the RAID removal process may take up to 1 minute to complete. The duration of this process depends on the size of the disk.
  
  If you administratively shut down the disk during the RAID rebuild process, a RAID rebuild abort alarm is generated instead.

To remove a RAID-1 disk, follow these steps:

Step 1 To manually shut down the disk, enter global configuration mode and then enter the disk disk-name diskxx shutdown command:

Step 2 Wait for the disk to be completely shut down before you physically remove the disk from the WAE.

Step 3 When the RAID removal process is complete, WAAS generates a disk failure alarm and trap. In addition, a syslog error message is logged.

Note We recommend that you disable the disk error-handling reload option if it is enabled because it is not necessary to power down the system to remove a disk.
