EMC Avamar Virtual Edition 7.2 Installation – Part 1

01

EMC Avamar Virtual Edition (AVE) is a single-node non-RAIN (Redundant Array of
Independent Nodes) Avamar server that runs as a virtual machine in a VMware® ESXi
5.1/5.5/5.5u2/6.0 environment. AVE integrates the latest version of Avamar software
with SUSE Linux as a VMware virtual machine.

AVE is similar to single-node Avamar servers in the following ways:
– Runs autonomously as a target for all Avamar client backups
– Performs replication to a physical Avamar system or another AVE
AVE is available in four configurations: 0.5 TB, 1 TB, 2 TB, and 4 TB licensed capacity. AVE is not scalable to a multi-node Avamar server and resizing the virtual machine is not
supported. You can increase storage capacity by deploying additional AVE virtual
machines, and then divide backups among them. Or you can replicate the data to
another Avamar server, delete the smaller virtual machine, create a larger virtual
machine, and replicate the data back to the larger virtual machine.

Installation procedure

1. Download the AVE virtual appliance (7z.file) at http://support.emc.com
2. Extract the compressed .7z file.
3. Start a VMware vSphere Client and connect to the vCenter Server or to the ESXi host that will host the AVE virtual machine.
4. Log in with administrative rights.
5. Select File > Deploy OVF Template. The Source page appears.
6. Select Deploy from a file or URL and browse to the AVE virtual machine file (OVF extension) and click Next.
7. Type in the AVE name, select the inventory location, and then click Next.
8 . The Storage page appears. Select the storage for AVE and click Next.
9. The Disk Format page appears. Select Thick Provision Lazy Zeroed format and click Next.
10. The Network Mapping page appears. Select the destination network and click Next.
11. The Ready to Complete page appears.Confirm the deployment settings are correct and click Finish.
PS: The installation may take several minutes. A Deployment Completed Successfully message appears when the installation is complete.
12.Click Close.
13.Right-click the AVE virtual machine and select Edit Settings.
14.On the Hardware tab, select Memory and set Memory Size based on the size of the
AVE license:
– For 0.5 TB AVE, specify 6 GB
– For 1 TB AVE, specify 8 GB
– For 2 TB AVE, specify 16 GB
– For 4 TB AVE, specify 36 GB
15.On the Hardware tab, select CPUs and change the number of virtual CPUs based on the size of the AVE license:
– For 0.5 TB AVE, specify 2 CPUs.
– For 1 TB AVE, specify 2 CPUs.
– For 2 TB AVE, specify 2 CPUs.
– For 4 TB AVE, specify 4 CPUs.
16.On the Hardware tab, select Network adapter 1, choose the Network Connection (Network label), and then select the correct network.
17.Create additional virtual hard disks (VMDKs) for the AVE virtual machine based on the specifications from AVE virtual disk requirements on following table.
AVE configuration Number of virtual disks
– 0.5 TB 3 storage partitions (250 GB each)
– 1 TB 6 storage partitions (250 GB each)
– 2 TB 3 storage partitions (1000 GB each)
– 4 TB 6 storage partitions (1000 GB each
PS: Disk Provisioning select Thick Provision Lazy Zeroed format.
18. After add the additonal virutal hard disk, then power on the AVE appliance.
19. Open the Virtual Console to monitor installation progress.

VMware Virtual SAN 6.2 – What’s New

Deduplication and Compression for Space Efficiency
Nearline deduplication and compression per disk group level.
Space Efficiency enabled on a cluster level.
Deduplicated when de-staging from cache tier to capacity tier.
Compressed after deduplication.

Erasure Coding (RAID 5)
Sometimes RAID 5 and RAID 6 over the network is also referred as erasure coding. In this case RAID-5 requires 4 hosts at a minimum as it uses a 3+1 logic. With 4 hosts 1 can fail without data loss. This results in a significant reduction of required disk capacity. Normally a 20GB disk would require 40GB of disk capacity, but in the case of RAID-5 over the network the requirement is only ~27GB. There is another option if higher availability is desired

Erasure Coding (RAID 6)
With RAID-6 two host failures can be tolerated, similar to FTT=2 using RAID-1. In the traditional scenario for a 20GB disk the required disk capacity would be 60GB, but with RAID-6 over the network this is just 30GB. Note that the parity is distributed across all hosts and there is no dedicated parity host or anything like that. Again, this is sometimes by others referred to as erasure coding. In this case a 4+2 configuration is used, which means that 6 hosts is the minimum to be able to use this configuration.
