What’s New in vSphere 6.0: Cross vCenter and Long Distance vMotion

August 26th, 2014 3 comments

VMware has finally officially announced what is to be included in vSphere 6.0 after lifting the lid on parts of the update during VMworld 2014 keynotes and sessions. 

See my introductory post: What’s New in vSphere 6.0: Finally Announced (about time!) for details of all the components.

vMotion is one of most basic yet coolest features of vSphere, People generally consider the time they saw vMotion work for the first time as their “wow” moment showing the power of virtualisation. in vSphere 5.5, vMotion is possible within a single cluster and across clusters within the same Datacenter and vCenter. With vSphere 6.0 vMotion is being expanded to include vMotion across vCenters, across virtual switches, across long distances and routed vMotion networks aligning vMotion capabilities with larger data center environments.

vMotion across vCenters will simultaneously change compute, storage, networks, and management. This leverages vMotion with unshared storage and will support local, metro and cross-continental distances.

imageYou will need the same SSO domain for both vCenters if you use the GUI to initiate the vMotion as the VM UUID can be maintained across vCenter Server instances but it is possible with the API to have a different SSO domain. VM historical data is preserved such as Events, Alarms and Task History. Performance Data will be preserved once the VM is moved but is not aggregated in the vCenter UI. the information can still be accessed using 3rd party tools or the .API using the VM instance ID which will remain across vCenters.

EVO: Rail – Integrated Hardware and Software

August 25th, 2014 No comments

VMware has announced it is entering the hyper-converged appliance market in conjunction with hardware partners for them to ship pre-built hardware appliances running VMware software. See my introduction, VMware Marvin comes alive as EVO:Rail, a Hyper-Converged Infrastructure Appliance.

image Each of the four compute nodes within the 2U appliance has a very specific minimum set of specifications. Some hardware vendors may go above and beyond this by adding say GPU cards for VDI or more RAM per host but VMware wants a standard approach. These kinds of servers don’t exist on the market currently other than what other hyper-converged companies whitebox from say SuperMicro so we’re talking about new hardware from partners.

Each of the four EVO: RAIL nodes within a single appliance will have at a minimum the following:

  • Two Intel E5-2620v2 six-core CPUs
  • 192GB of memory
  • One SLC SATADOM or SAS HDD for the ESXi boot device
  • Three SAS 10K RPM 1.2TB HDD for the VSAN datastore
  • One 400GB MLC enterprise-grade SSD for read/write cache
  • One VSAN certified pass-through disk controller
  • Two 10GbE NIC ports (either 10GBase-T or SFP+ connections)
  • One 1GbE IPMI port for out-of-band management

Each appliance is fully redundant with dual power supplies. As there are four ESXi hosts per appliance, you are covered for hardware failures or maintenance. The ESXi boot device and all HDDs and SSDs are all enterprise-grade. VSAN itself is resilient. EVO: RAIL Version 1.0 can scale out to four appliances giving you a total of 16 ESXi hosts, backed by a single vCenter and a single VSAN datastore.There is some new intelligence added which automatically scans the local network for new EVO:RAIL appliances when they have been connected and easily adds them to the EVO: RAIL cluster.

EVO: Rail – Management Re-imagined

VMware has announced it is entering the hyper-converged appliance market in conjunction with hardware partners for them to ship pre-built hardware appliances running VMware software. See my introduction, VMware Marvin comes alive as EVO:Rail, a Hyper-Converged Infrastructure Appliance.

image The EVO: RAIL management software has been built to dramatically simplify the deployment of the appliances as well as provisioning VMs. The user guide is only 29 pages so you can get an idea of how VMware is driving simplicity. Marvin actually exists as a character icon within the management interface with an embedded “V” and “M”.

VMware recognises that vCenter has had a rather large feature bloat problem over the years. They have introduced new components like SSO which do provide needed functionality but add to the complexity of deploying vSphere. VMware has also tried to bring all these components together in the vCenter Server Appliance (VCSA).

This is great but has some functionality missing compared to the Windows version like Linked-Mode and some customers worry about managing the embedded database for large deployments. As EVO:RAIL is aimed at smaller deployments and isn’t concerned with linking vCenters together, the VCSA is a good option and the EVO:RAIL software is in fact a package which runs as part of the VCSA. There is no additional database required, it is all built into the appliance and uses the same public APIs to communicate with vCenter but acts as a layer to provide a simpler user experience, hiding some of the complexity of vCenter. vCenter  is still there so you can always connect directly with the Web Client and manage VMs as you do normally and any changes made in either environment are common so no conflicts.

EVO:RAIL is also also written purely in HTML5 even for the VM console, no yucky Flash like the vSphere Web Client and it works on any browser, even an iPad. Interestingly is has a look which is a little similar to Microsoft Azure Pack. Who would ever have thought VMware would have written a VM management interface built for simplicity that is similar to an existing Microsoft one!

VMware Marvin comes alive as EVO:Rail, a Hyper-Converged Infrastructure Appliance

August 25th, 2014 1 comment

image image VMware will announce shortly today at VMworld US that it is entering the hyper-converged appliance market with a solution called EVO:Rail. This has been rumoured for a while since an eagle eyed visitor to the VMware campus spotted a sign for Marvin in their briefing center. Marvin was the engineering name and has still stuck around in parts of the product but its grown up name is EVO:Rail.

EVO(lution) is eventually going to be a suite of products/solutions, Rail is the first announcement named for the smallest part of a data center rack, the rail, so you can infer that VMware intends to build this portfolio out to an EVO:RACK and beyond.

EVO:Rail combines compute, storage and networking resources into a hyper-converged infrastructure appliance with the intention to dramatically simplify infrastructure deployment. Hardware wise this is pretty much what Nutanix and Simplivity as two examples do today. Spot the acronym, HCIA, to hunt for newly added VMworld sessions.

VMware is not however entering the hardware business itself, that would kill billions of marketing budget spent on the Software Defined Data Center message of software ruling the world. Partner hardware vendors will be building the appliance to strict specifications with VMware’s EVO:RAIL software bundle pre-installed and the appliance delivered as a single SKU. Some may see this as a technicality. VMware has always said if you need specific  hardware you are not software defined. Does EVO:RAIL count as specific hardware?

Support will be with the hardware vendor for both hardware and software with VMware providing software support to the hardware vendor at the back-end.

What VMware’s EOL of vCenter Server Heartbeat means for availability?

June 6th, 2014 2 comments

image VMware has very surprisingly and suddenly stopped selling vCenter Server Heartbeat from 2nd June 2014. If you have already purchased vCenter Server Heartbeat you will still get support until 2018 so no panic that the whole carpet has been pulled from under your feet but it does beg the question, what to do going forward to make your vCenter installation more highlight available if you need it?

In the EOL announcement, VMware suggests first of all making your vCenter a VM to be able to take advantage of HA to provide high availability. If you cannot for some reason (and you really need to ask yourself why) run vCenter as a VM and it is/needs to be physical then the only solution is to use a backup solution to be able to restore vCenter if it fails.

What’s New in vCloud Suite 5.5: vSphere Replication and vCenter Site Recovery Manager

August 26th, 2013 No comments

VMware has announced its latest update to version 5.5 of its global virtualisation powerhouse, vCloud Suite.

To read the updates for all the suite components, see my post: What’s New in vCloud Suite 5.5: Introduction

vSphere Replication

replication-image3.jpg What’s New:

  • The user interface within the Web Client has been beefed up. The VM and vCenter management panes have been enhanced to configure and monitor replication.
  • You can now deploy new vSphere Replication appliances to allow for replication between clusters and non-shared storage deployments and also to meet load balancing requirements.
  • There are now multiple points-in-time snapshots so if you have VM with an OS corruption that has already been replicated you can select an earlier snapshot to recover from before the corruption occurred. This isn’t the same is replicating VMs with existing snapshots which isn’t supported. Point-in-time snapshots are created at the recovery site after replication.
  • There is now Storage DRS Interoperability so replicated VMs can be Storage vMotioned across datastores without interrupting ongoing replication.
  • VSAN support has been added to protect and recover VMs running on the new VSAN datastores.

vCenter Site Recovery Manager

What’s New:

  • recovery Storage DRS and Storage vMotion are now supported when VMs are migrated within a consistency group.
  • VMs running on (Virtual SAN) VSAN datastores can be protected using vSphere Replication. You can use VSAN datastores on both the protected and recovery sites. There are a few considerations when using VSAN and SRM so read the documentation.
  • You can now recover and preserve multiple point-in-time snapshots of VMs that were protected with vSphere Replication.
  • VMs that reside on Virtual Flash (VFlash) can be protected. VFlash is disabled on VMs after recovery.
  • IBM DB2 is no longer supported as an SRM database

What’s New in vCloud Suite 5.5: vCloud Networking & Security

August 26th, 2013 No comments

VMware has announced its latest update to version 5.5 of its global virtualisation powerhouse, vCloud Suite.

To read the updates for all the suite components, see my post: What’s New in vCloud Suite 5.5: Introduction

sec vCloud Networking and Security has been updated with two networking enhancements, LACP and flow based marking & filtering.

Link Aggregation Control Protocol (LACP) is used to bond your physical network uplinks together to increase bandwidth, have better load balancing and improve link level redundancy. vSphere5.1 supported a simplified version of LACP with support for only a single Link Aggregation Group (LAG) per host and not much choice of load balancing algorithms.

LACP in 5.5 gives you over 22 load balancing algorithms and you are now able to create 32 LAGs per host so you can bond together all those physical Nics.

Flow based marking and filtering provides granular traffic marking and filtering capabilities from a simple UI integrated with VDS UI. You can provide stateless filtering to secure or control VM or Hypervisor traffic. Any traffic that requires specific QoS treatment on physical networks can now be granularly marked with COS and DSCP marking at the vNIC or Port group level.

Manageability has been enhanced in the vSphere Web Client with an object-policy based model.

Firewall Rule management has been made easier. You can now reuse vCenter objects in firewall rule creation and there is an option to create VM vNIC level rules with full visibility into the virtual network traffic via Flow Monitoring.

Upgrades

To upgrade vShield, you must first upgrade vShield Manager and then upgrade the other components in this order:

  1. vShield Manager
  2. vCenter Server
  3. Other vShield components managed by vShield Manager
  4. ESXi hosts

You can upgrade just vShield to 5.5 if you want and still run vCenter Server 5.1 and ESXi 5.0/5.1 hosts.

What’s New in vCloud Suite 5.5: vCloud Director

August 26th, 2013 No comments

VMware has announced its latest update to version 5.5 of its global virtualisation powerhouse, vCloud Suite.

To read the updates for all the suite components, see my post: What’s New in vCloud Suite 5.5: Introduction

director vCloud Director 5.5 has been updated with changes to the Content Catalog, vApp provisioning and lifecycle management process, an improved OVF import/export function and new browser support including Mac OS.

vCloud Director Virtual Appliance

The vCloud Director Virtual Appliance is still only to be used for PoC and Eval use for simple deployment and setup. With the appliance you can choose to use an internal/embedded database or an external MS SQL or Oracle database. Hopefully the appliance is extended in the future to be the default deployment solution in some highly available way or maybe even merged with vCenter.

vCD is still a standalone web client, not integrated as an extension to the vSphere Web Client. There are contextual shortcuts to help you navigate between the two. I don’t actually think that vCD in the future will become an extension to the vSphere Web Client but the admin functionalities of vCenter and vCloud Director will merge into a single appliance but this is just speculation.

What’s New in vCloud Suite 5.5: VMware Virtual Flash (vFlash)

August 26th, 2013 No comments

VMware has announced its latest update to version 5.5 of its global virtualisation powerhouse, vCloud Suite.

To read the updates for all the suite components, see my post: What’s New in vCloud Suite 5.5: Introduction

speed VMware Virtual Flash (vFlash) or to use its official name, “vSphere Flash Read Cache” is one of the new standout feature of vCloud Suite 5.5.

vFlash allows you to take multiple Flash devices in hosts in a cluster and virtualises them to be managed as a single pool. In the same way CPU and memory is seen as a single virtualised resource across a cluster, vFlash does the same by creating a cluster wide Flash resource.

VMs can be configured to use this vFlash resource to accelerate performance for reads. vFlash works in write-through cache mode so doesn’t in effect cache writes in this release, it just passes them to the back-end storage. You don’t need to use in-guest agents or change the guest OS or application to take advantage of vFlash. You can have up to 2TB of Flash per host and all kinds of datastores are supported, NFS, VMDK and RDMs. Hosts can also use this resource for the Host Swap Cache which is used when the host needs to page memory to disk.

A VMDK can be configured with a set amount of vFlash cache giving you control over exactly which VM disks get the performance boost so you can pick your app database drive without having to boost your VM OS disk as well. You can configure DRS-based vFlash reservations, there aren’t any shares settings but this may be coming in a future release. vMotion is also supported, you can choose whether to vMotion the cache along with the VM or to recreate it again on the destination host. vSphere HA also is supported but when the VM starts the cache will need to recreate again on the recovery host.
