Current status of virtualization
in SJC
7
Reasons to use virtualization

SJC will launch 4 satellites within 2 years.
 work on reducing the operational load in several ways
 One of the way is virtualization of EPOCH IPS

Virtualization refers to the creation of a virtual machine that acts like a
real computer with an operating system(#).
Traditional Architecture

(#)Wikipedia: https://en.wikipedia.org/wiki/Virtualization
8
Reasons to use virtualization
SJC decided
to use VMware as a virtualization software for EPOCH IPS.
VMware
has a lot of merits as follows:
Cost effective
Resource Optimization, Saving Rack space, Consumed Power
Functions to Reduce Operational Load
vMotion, Snapshot, cloning, HA, Backup, Converter, and so on.
Last year,
SJC verified following points:
Essential functions of VMware work as expected
EPOCH IPS on Virtual Server is working just like on a Physical Server
9
The relation between virtualization and increase of EPOCH IPS


EPOCH IPS constitutes an increasingly large portion of the SJC.
The more the percentage of EPOCH IPS is increasing, the more we’ll see
the effect of virtualization of EPOCH IPS go up.

Current situation and virtualization plan in the future


SJC has virtualized only part of EPOCH IPS servers.
SJC will continue to virtualize other servers and to investigate the
appropriate method to virtualize workstation.

Functions of VMware and
how SJC uses it
12
Physical Configuration Overview
VMware
is Installed on both of 2 dell servers
Virtual Machines (VM) are saved to a Shared Disk.
One of 2 VMware ESXis loads and executes VM onto its memory

Saving Rack Space of Physical Configuration


Lots of VM are consolidated and working on these machines.
Hardware failure has a significant impact on VM, so it’s necessary to
make each Machine as a redundant configuration.

Basic License Type of VMware

So far, SJC is using Essentials Plus License of VMware that is reasonable
but has many functional restrictions.

This License enables us to:
 Use basic functions such as vMotion, Snapshot, clone, HA, and VDP

This License doesn’t enable us to:
 Scale-out more than 3 servers
 Use advanced functions such as FT, DRS, Storage vMotion, App-HA,
and so on

vMotion

vMotion enables running VM to move into another server with zero
downtime

SJC confirmed that EPOCH server can finish its vMotion process without
disconnecting from DSS.

16
Snapshot

Snapshot preserves the state of the VM at a specific point in time.

When you revert to a snapshot, you discard all changes made to the VM
since you took the snapshot.
①Take a snapshot
⑤return to Stable state
Stable state
②Apply Patch
③become Unstable state
④Back to the previous state
17
Clone

Clone is a copy of an existing virtual machine.

If you want to make a copy of a virtual machine for separate use, create
a clone.

If you want to save the current state of the virtual machine, so you can
revert to that state in case you make a mistake, take a snapshot.

VMware Data Protection (VDP)

VDP is an agent-less, image-level VM backup tool

Saving a lot of backups causes unstable state of VDP, so SJC set up
backup schedule of VDP as following
 Once
a day for 7 days, Once a week for 4 weeks, Once a month for 12 months

vCenter Converter




It’s hard to rebuilt already running EPOCH IPS servers as a VM.
vCenter Converter enables us to convert EPOCH IPS into VM easily.
SJC conducted load tests of the converted EPOCH server on VM, and
confirmed it works fine.
SJC has already been operating the converted EPOCH Server as a VM.

Other features of VMs

VM is just a file, so it’s easy to move VM between a production
environment and a test environment.

Points of concern
about virtualization
23
Points of resource allocation

It’s necessary to decide resource allocation size of each VM.
 Resources are such as number of CPU cores, Memory size, and HDD size

If the resource allocation size is too much, and the total of all the VM’s
actual resource consumption exceeds physical server’s resource size, all
unprotected VMs become unstable.

On the other hand, if the resource allocation size is too little, it affects the
performance.

To prevent these situations, it’s necessary for important VMs such as
EPOCH server to investigate and to reserve (a function to assure allocated
resource) the minimum requirement of resource size.
24
Resource allocation size of each EPOCH IPS server in SJC

SJC conducted load tests and observed the resource utilization of each
EPOCH IPS server.
Specific resource allocation size of each EPOCH IPS server in SJC (#)

2～
Memory
8GB～
4GB～
4GB～
HDD
100GB～
30GB～
30GB～

These specs are smaller than on Physical servers, yet they’re working fine.

The appropriate size depends on the use case scenario.
(#) The memory and HDD sizes will greatly differ according to whether or not we use the memory over commit and the thin provisioning functions
(SJC tries not to use these functions)
25
Failure detecting and resource monitoring

Hardware failure and resource shortage on the Physical Machine have a
significant impact on all virtual machines.

SJC built an NMS server to detect Hardware, VMware Hypervisor,
vCenter process failure and to monitor resource utilization.

Conclusion
27
Advantages and Disadvantages of VMware


There was a lot of hard work involved in our first introduction of
virtualization of EPOCH IPS as follows

to consider hardware specs, redundancy design, and migration plan

to prepare the way of failure detecting and resource monitoring (#)
However, VMware functions provide the benefit of increasing the
efficiency of the system operation.
(#) Preparing fault isolation methods is indispensable. If something happened to a VM, He that is unfamiliar with virtualization may doubt VMware.

Appendix
30
Total optimization in the next stage

SJC is working on virtualizes only servers in main site for now, however
it’s necessary to consider multi-site design. For example,
 SJC needs sufficient number of client only in case of emergency in
other site.
 There is some possibility to make unused licenses that can be used
for a purpose of replace TCR/STA to EPOCH IPS.

31
Ideal design of HA configuration

It may be possible to monitor the EPOCH server on the VM with higher
class license and custom settings of VMware.

This way is smart because it’s not necessary to prepare EPOCH Server on
the each VMware ESXi, but we have to consider the failover downtime,
reconnection with client / baseband, and get over some hurdles as
mentioned above.

VMware HA in SJC

If the application's process finishes, we want VMware to reboot the
application to recover. However, due to the licensing constraints and
other problems, this is not realized for now.

SJC prepares EPOCH server on the each VMware ESXi for redundancy.

Problem that we have to solve

SJC needs the way to confirm whether or not EPOCH IPS server process is
alive without monitoring GUI. As one of the methods, we can use “ps aux
| grep epoch”, but it’s an uncertain way.

Does anyone know any monitoring functions of the EPOCH server like the
“statusEpoch” command?
