Chapter 1 Installing & Initializing Sangfor HCI
Software

Sangfor HCI software provides an Enterprise-class cloud management platform which

integrates resources, such as compute, networking and storage, etc. It is often defined
according to requirements of business system and can help to build data center and deploy
business system more easily. It combines compute, networking and storage capabilities onto
industry-standard x86 servers by using virtualization technologies. All the resources are
aggregated into a resource pool on node basis that is easy to scale out.
Sangfor HCI is a suit of software which is installed on a physical server, and used to virtualize
servers and resources of physical server (CPU/memory/storage, etc), and to provide guest
operating systems with complete hardware system functions and independent operating
environment, which are called virtual machines.
This section introduces the installation of Sangor HCI software and requirements for
hardware. After the software is installed properly, you also need to configure it, and do
debugging.

aSV refers to management software or operating system of Sangfor HCI, if not otherwise
specified.

1.1Hardware Requirements
Before installation, a number of physical servers are needed. Performance of virtual
machines is determined by that of server’s CPU, memory, and storage. The better the
server’s performance, the better virtual machine’s user experience will be.
Additionally, there are some requirements for the physical server on which you want to install
the Sangfor HCI software.
The server’s CPU must support Intel Intel Virtualization Technology(VT) or AMD-V. For some
servers, it is required to enable VT-x in BIOS.
Memory of the server must be greater than 16GB.
Free disk space of the server must be greater than or equal to 60GB. To run virtual machines,
data disk is also required. You can use external iSCSI or FC storage, or build virtual storage by

1.3.2.1 Configuring Storage Network Interfaces

Go to Storage and click Settings on the dialog that pops up to configure storage deployment
mode.
By default, eth0 is used as management interface and communication interface to
synchronize configurations on Sangfor HCI platform. Storage network interface is used to
synchronize file data on virtual storage. It is better to use separate interfaces as management
interface and storage network interface. For storage deployment mode, Link aggregation
with one switch is recommended.

T.: +60 12711 7129 (7511) | E.: te ch.support@sangfor.co m | W .: www.sangfor.com

15
Each node communicates with another one using two physical interfaces which are
connected to a same layer 2 switch. Storage network interfaces will be aggregated
automatically without the need to configure link aggregation on switch. After the
deployment mode is selected, you need to deploy the network according to the digram
illustrating deployment architecture of storage area network, and then select storage
network interface for each node and configure IP address for that interface.

Storage area network is built after storage network interface is configured.

Testing Connectivity
On the Virtual Storage dialog, click on Test Connectivity button to enter the following page.
On that page, specify an IP address(it is often the gateway address)which should be allowed
to ping, in order to check if the node is connected.

1.3.2.2Configuring Overlay Network Interface

After a cluster is created, you need to configure overlay network interface for each node.
Overlay network interface must be a Gigabit or 10-Gigabit interface and connected to a
Gigabit or 10-Gigabit switch (If there are only two nodes, connect two overlay network
interfaces directly without using any switch). To improve bandwidth and redundancy of
overlay network interface, you can use an aggregate interface as a overlay network interface.
By default, management interface and overlay network interface are set to a same interface.
To improve data transmission efficiency, configure the management interface and overlay
network interface(VXLAN) to reside on different physical NICs. To configure overlay network
interface, go to Nodes > Communication Interface > Overlay Network Interface(vxLAN).
Specify an overlay network interface for each node and configure a corresponding IP address
and netmask.

20
To improve data transmission efficiency, enable high performance mode. In that mode, MTU
will be changed to 1600 and therefore VXLAN encapsulated data will not be fragmented
when being forwarded to physical network, but Jumbo Frame must be enabled on the
physical switch connected to a host installed Sangfor HCI software.

1.3.3 Configuring Edge

If multiple nodes form a cluster and provide business service as a whole, a virtual machine
may run on any node, therefore, an edge should be connected to an interface on each node
and that interface should be connected a same L2 physical switch, ensuring that virtual
network traffic can go into physical network through any node.

1.3.4 System Upgrade

For Sangfor aServer, the pre-installed operating system may not be the latest version. To
gain better virtualization experience, it is better to upgrade system to the latest version.
Before upgrade, enable Maintenance Mode first in System > System Maintenance >
Upgrade. Then, click on Upgrade button and upload a pkg update package. After the update
package is uploaded successfully, click Start.
After upgrade completes, click Restart All Nodes to make upgrade operation take effect.
Maintenance mode will be automatically disabled during restart of nodes.
After all nodes start up again, check running status of each node, and make sure nodes and
virtual machines run properly after upgrade.

2.2.1.12 Deploying VM

Generally speaking, a VM template is a virtual machine which has been configured, and can
be used to deploy multiple virtual machines with the same configurations. The difference
from cloning VM is that disk files will not be replicated when a virtual machine is deployed
from a template. What’s more, changes made to template will be saved to de virtual machine
incrementally.
Deploy VM: Only the virtual machine converted to template can be used to deploy virtual
machines. Disk settings of the virtual machine after being converted to template cannot be
changed any more. You may deploy new virtual machines when converting a virtual machine
to template. Deployed virtual machines have the same configurations as that of its template.

Name of the deployed VM depends on the Name and the number of virtual machines. For
instance, name of VM is name and number of virtual machines is 2, then names of the two
new virtual machines are name_0001 and name_0002 respectively.

Migrate to another node if the node fails: If this option is selected, deployed virtual
machines will be automatically migrated to another node if the working node fails.

Datastore: Specifies a datastore where configuration files of deployed virtual machines are

new virtual machine will have a new hardware ID. you need to reauthorize the virtual
machine if guest OS or software reauthorization is bound with hardware ID. To not perform
reauthorization, choose the other way.

After recovery method is chosen, you need to specify destination location, including VM
Name, Group, Datastore and Run on Node fields.

VM Name: Specifies a name for the recovered virtual machine.

Group: Specifies a group to which the virtual machine is recovered.
Datastore: Specifies a datastore for the recovered virtual machine.

2.3.5.1.7 Configuring Advanced Settings

On the Advanced tab, you can enable high availability (HA) and specify a node to run the
virtual router.

To enable HA, select the option HA. If HA is enabled, a second router will be built on another
node and synchronize data in real time. If one node fails, the second router will take over
seamlessly. However, synchronizing data between the two routers will consume extra
network bandwidth.
Without high availability enabled, the router will still recover to a second node, but it will take
longer to get up and running.

[Router Running on Node]: By default, the node where the router runs is automatically
selected according to the settings on the following page. You can change the current node
running the router as per your need.

2.4.2 Virtual Storage

Sangfor virtual storage (later renamed Sangfor aSAN)) is storage virtualization software
developed based on distributed file system, to adapt to the trend of storage virtualization.
Currently, aSAN software is embedded into Virtualization Management Platform (VMP),
through which all hard disks (except for system disk) on the physical machines in a cluster are
managed together.
On the Virtual Storage page, there are four tabs, Virtual Datastores, Shared Disks, iSCSI
Virtual Disks and Physical Disks, as shown below:

2.4.3 Virtual Datastores

Storage of a cluster with 6 or more than 6 nodes can be divided into different virtual
datastores, so as to meet requirements for IO data and performance segregation for
different businesses. Each resource pool is a virtual datastore.
On the Virtual Datastores tab, it displays name, status, total capacity, usage, read and write
speed, number of replicas, nodes, disks and virtual machines, as shown below:

To view detailed information of a virtual datastore, you may click on the name of the virtual
datastore. For details, you may refer to the Error! Reference source not found..
To view disks in detail and manage disks, you may click on the number under Disks. For

2.4.3.1 Creating Virtual Datastore

To create a new virtual datastore, there must be at least three nodes. There are four steps to
create a new virtual datastore: 1) Specify basic information 2) Select node(s) 3)Specify use of
disk 4)Confirm configurations. The following illustrates the creation process in details:

1. Specify basic information for the virtual datastore. You should specify virtual datastore
name and number of data replicas, 2 replicas or 3 replicas.
2 replicas (recommended): Indicates that all data has two replicas stored on two nodes
respectively. Total disk space should be doubled to ensure certain amount of space
available. Featuring rapid data reconstruction, rapid backup and continuous data
backup (CDP), this solution caters to majority of the scenarios and offers a balance on
costs and data safety.
3 replicas: All data has three replicas stored on three nodes respectively. Total disk space
should be three times to the actual space.

3. Specify use of disk.
In this step, you will see the following information of discovered disks(system disk is not
listed): disk name, disk type, disk size and use of disk. Then, you should specify use of
those disks. Disks that are added to virtual storage can be used as data disk, cache disk
or spare disk.
Data disk: It is used to store disk data files of virtual machine and create virtual disk. Its
capacity should be greater than or equal to 200GB.
Cache disk: It is used for caching, to improve performance of virtual storage. SSD is often
used as cache disk. Its capacity should be greater than or equal to 100GB. Since version
HCI5.3, SSD cannot be used as cache disk to add to virtual datastore if it is not an SSD for
data center, and storage performance may be affected without cache disk.
Spare disk: It acts as backup of data disk on virtual storage, and is always ready to replace
the data disk when it fails. Once the failed disk recovers, it returns to spare disk. Its
capacity should be greater than or equal to 200GB.
If none of the above uses is selected for disk, it may not associate with virtual storage.

4. Confirm configuration.
After configuring use of disk, you need to type admin password to confirm the operation
of creating virtual datastore.

2.4.3.2 Expanding Capacity

Capacity of a virtual datastore can be expanded by adding more nodes or disks to it. Before
expanding capacity via node, storage network interface of the new node should be specified.
Steps of capacity expansion include the followings: 1) Select virtual datastore for which you
want to expand capacity 2) Select a type to expand capacity 3) Specify use of disks 4)Confirm
configurations.

1. Select virtual datastore.

There is a list displaying information of virtual datastore: datastore name, total capacity,
free space, the number of nodes, the number of disks that have been used and the
number of free disks. From the list, select the datastore for which you want to expand
capacity.

3. Configure use of disk.
In this step, you will see the following information of available disks(system disk is not
listed): disk name, disk type, disk size and use of disk. Then, you should specify use of
those disks. Disks that are added to virtual storage can be used as data disk, cache disk
or spare disk.
Data disk: It is used to store disk data files of virtual machine and create virtual disk. Its
capacity should be greater than or equal to 200GB. The number of data disks should be
multiple of the data replicas, or else some data disks cannot be added to virtual
datastore.
Cache disk: It is used for caching, to improve performance of virtual storage. SSD is often
used as cache disk. Its capacity should be greater than or equal to 100GB. Since version
HCI5.3, SSD cannot be used as cache disk to add to virtual datastore if the SSD is not an
SSD for data center, and storage performance may be affected without the cache disk.
Spare disk: It acts as backup of data disk on virtual storage, and is always ready to replace
the data disk when it fails. Once the failed disk recovers, it returns to spare disk. Its
capacity should be greater than or equal to 200GB.
If none of the above uses is selected for disk, it may not associate with virtual storage.

Data Balancing: You can create data balancing task for different virtual datastores. After the
task is created, available storage space of each node will be restricted within a certain range.
If the remaining storage space is below a certain range, the data balancing task will be
executed automatically to have VM files stored on the node short of resources moved to
another node. Data that have been migrated will be evenly written into each disk so as to
keep disk usage balanced.

Since performance of virtual machine will be affected during data balancing,virtual machines
of high priority will not chosen to perform data balancing. Virtual machines will not be
migrated back immediately after migration.

197
Data Rebuilding: Taking data with two-copy policy as the example, when components (disk
or host) in storage volume suffer physical fault, the other copy of the data of faulted
component is stored on other components to ensure normal reading and writing of virtual
machine, but meanwhile the redundancy of storage volume is reduced, which will lead to
data loss if the component storing the other copy also breaks down.With data reconstruction,
when component breaks down, the other copy of the data on faulted component will be used
as the recovery source to reconstruct a new copy on the target component in fragments to
recover completeness of the copy and realize system self-recovery.
you can specifie the time for confirming certain node or disk failure before data rebuilding.if
the time is reached but the issue is still not fixed,data rebuilding will be executed
automatically,as shown below:

Bad Sector Scanning: Hard disk will be periodically scanned for bad sectors. If any bad sector
is detected, disk repairing will be conducted. To ensure scanning speed, it is better to perform
scan during off-peak hours.

IO Timeout Handling: When IO read latency on a VM is higher than the threshold specified
below, the system will automatically read data from other VM replicas to ensure business
continuity.

Linked Clone: As virtual machines cloned from a certain virtual machine use the same data
by default and too many uses of that data will cause read/write load balancing issue. To
ensure business performance and continuity, you may specify a data reuse limit below, so
that a new piece of data will be automatically duplicated for subsequent reads and writes.

Storage Area Network: You can change deployment mode(Link aggregation disabled,
Link aggregation with one switch, Link aggregation with two switches) in Settings,as

Independent storage area network is more efficient in data transmission and consistent in
data sync. Furthermore, independent storage area network helps to reduce data sync risk
caused by network connection error, since virtual storage contains crucial business data. The
drawback is that additional interface must be provided on the node for the storage to
communicate across nodes
Test Connectivity: It is used to test whether the node is offline. First, you need to specify an
IP address which should better be router IP address.

In case that the working node gets offline, virtual machines running on it may be recovered
on another clustered node, which may lead to two instances for one virtual machine when
the failed virtual machine recovers and interrupts the service. For that reason, we need to
stop the instance on the offline node to ensure business continuity.

VM Running Across Datastores: This enables virtual machines to run across virtual
datastores. It should be configured only when the number of virtual datastores is greater
than or equal to 2. IP addresses in the pool should be in a 24-bit subnet that is exclusively
used by the cluster.

Intelligent Rate Restriction: Restrict data transfer rate for ongoing non-business tasks such
as data migration and reconstruction，etc,accordiing to IO performance,to ensure business

216
 iSCSI initiators can access virtual iSCSI disk via target IP address, to gain high availability
and load balancing. Each clustered node will be assigned an IP address from virtual IP
pool. Thus, initiator connections to a specified target IP address will be scheduled to
different nodes. This has the following strengths:
No single-point of failure: Once a node fails, iSCSI connections to the node will be
scheduled to another node.
Load balancing: Initiator connections to a specified target IP address will be evenly
scheduled to different nodes to access virtualized iSCSI disks in virtual storage, so as to
realize load balancing.
Click OK to save the changes. Changes to target portal should also be made at iSCSI
initiator side, and if there is any change made to network interface, the iSCSI network
should be reconfigured correspondingly.

2.4.6.1.3 Load Balancing

If the iSCSI connections to nodes are not balanced, click Perform Again to re-schedule
initiator connections to different nodes so as to ensure iSCSI connections evenly assigned to
each clustered node. iSCSI connections will be preferentially scheduled to the node which
has LUN replicas, which helps to enhance IO performance and reduce network load.
Rebalancing load will make some iSCSI connections disconnected and requires administrator
to enter password of the username to confirm operation.

stable. Under normal circumstances, Sangfor HCI GUI is reachable with IP address of any
managed node unless the node fails. With cluster IP address, you will never lose control of
the management even when one node fails unexpectedly.
Sangfor HCI management through cluster IP address improves system stability and
reliability dramatically.

Sangfor HCI can communicate with aCMP on the cluster IP address. To use relevant features
of aCMP, the following should be configured, Cluster IP, Netmask and Cluster Name, and
click Save to save the changes.

2.6.12 VM Backup and Recovery

In this Internet era, data has become the first productivity and data security has gained more
and more attention. Data loss or data damage, no matter due to human behaviors or natural
disaster, will bring about immeasurable loss to enterprises. Therefore, restoring data from
data replicas in the case of data loss becomes more important. On Sangfor HCI platform, the
first backup is a full copy of data and the successive backups are incremental backups in
which successive copies of the data contain only that portion that has changed since the
preceding backup copy was made, which backs up less amount of data, occupies less space,
and speeds up backup process as well. When a full recovery is needed, the restoration
process needs the last full backup plus all the incremental backups until the point of
restoration. Incremental backups are desirable as they reduce storage space usage, and are
quicker to perform.

 Due to the fact that CPU and memory data of virtual machines are not synchronized
among different nodes, data may be lost when virtual machines are migrated onto
another node.

2.6.14.2 Resource Scheduling

Resource scheduling refers to migrating virtual machines to another node when running
low on resources, so as to guarantee business stability and continuity. Resource
scheduling will be triggered if CPU and/or memory usage of node exceed(s) the
threshold that has been specified, and virtual machines will be migrated according to
the automation level. Virtual machines will be migrated to nodes whose CPU and/or
memory usage is low, so as to lowering resource usage of nodes to be within the
threshold.

You may specify threshold for CPU or memory(50%-90%), or for both. Migration
recommendations will be given when threshold is reached.

You may specify sensitivity level, conservative(recommended) or aggressive. If

conservative is selected, migration will be triggered if CPU and/or memory usage
exceed the above usage for 10 minutes. If aggressive is selected, migration will be
triggered if CPU and/or memory usage exceed the above usage for 3 minutes.
