*total in pairing, not per site

site is now the protected site. The reprotect also flip-

flops any IP customizations you may have configured.

Last thing it does is start replication.

Array-Based Replication (ABR) Sizing

• EMC® RecoverPoint Appliance - Journal LUN > 20%

• Usable datastore size x % RoC (daily Rate of Change)

x # of days = Journal size

• Example: 10TB datastore, 6% RoC, 7 day Site Recovery

Manager test: 10TB x 6% x 7 days = 4.2TB journal space

• NetApp®

• Minimum 20% for Snapshot reserve

• Requires FlexClone® and SnapMirror® license

VMware vSphere® Replication [VR]

• Replication at the VM host level

• More for SMB use

• One VR appliance per vCenter (contains management

server and first VR server)

• Can deploy nine additional VR servers

• VR management server can manage up to 500 VMs

• VR max disk size of 2032GB

Networking

• No IP changing within the guest requires extending

VLANs or creating mirrored network segments

• Use Site Recovery Manager’s GUI to set protected and

recovery site IP configuration on a per-VM basis

• Use Site Recovery Manager’s dr-ip-customizer.exe to

export/import CSV of IP configurations at the Site

Recovery Manager level

Third-Party Certificate Requirements

• commonName (CN) = srm

• subjectAltName = fqdn.of.srm.server

• extendedKeyUsage = serverAuth, clientAuth

Site Recovery Manager Functions

  Test – Non-disruptive function which powers on VMs at

the recovery site without taking the protected site offline

to test the functionality of Site Recovery Manager. Utilizes

a snapshot or clone of the target side storage to present

to the hosts. Replicated data from the source site wil l be

queued until test is complete, ensuring adequate storage

space to run a test. You have the option to run a storage

sync prior to powering on test VMs to get latest data

possible.

Cleanup – Completion function to end the test.

Destroys/deletes the storage snapshot and erases all

changed data at the recovery site. No changes to the

test VMs are saved.

  Recovery – Actual disaster recovery function. In “planned”

mode, syncs storage, shuts down VMs, removes storage

from hosts and sets as read-only, performs another sync.

If you have suspended hosts at the recovery site, Site

Recovery Manager can bring them online. Also, if you’re

running dev/QC/staging VMs at the recovery site, Site

Recovery Manager can suspend those VMs so no data

is lost. Site Recovery Manager then sets the target-side

storage as read-write and presents the storage to the

hosts, imports the VMs and powers them on. In a disaster,Site Recovery Manager will still try to sync storage and

gracefully shutdown the VMs, but understands to continue

upon failure of those steps. If the recovery is a fail-back

function and you had dev/QC/staging VMs suspended,

Site Recovery Manager will resume those VMs.

  Reprotect – Function to enable fail-back. The reprotect

sets up storage replication back the other direction. It also

reconfigures the Site Recovery Manager pairing to set the

current vCenter as the protected site and the old source
