Migrating volumes with EqualLogic features

During an array migration usually you can use application level trick to move your data between the old and the new array. For example with VMware vSphere you can use the Storage vMotion features (now added also in lower edition of vSphere 5.1) or with Microsoft Hyper-V 3 you can use the new Storage Live Migration feature. But in some case you may have also an option at storage level. For example to migrate across two Dell EqualLogic array (also different models) you can use the embedded function. The trick its simple: just add the new EqualLogic as an additional member in ...

Manage a storage array with System Center VMM 2012

One of the interesting features of System Center Virtual Machine Manager 2012 is that it can handle several other objects and not only the VM (when the name will be changed to reflect this?). Of course it can handle hosts (not only Hyper-V hosts), but also networking and storage. All those resource are in the "fabric" tab. In this case we see a storage array with its LUNs: The storage integration in System Center is really similar to several storage plugins for VMware vCenter and the VASA functionality on vSphere 5 (in fact it also require a "provider"): you can manage your ...

Cloud related FAQ

What is virtualization and how it's related to cloud? There are different types of virtualization levels (system, applications, networking, storage, ...). But basically it's an abstraction useful to created different contexts. Virtualization could be used as an abstraction level of a cloud computing solutions, but virtualization does not imply cloud. What is cloud (computing)? According with the NIST Definition of Cloud Computing, a cloud has those essential characteristics: On-demand self-service. A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider. Broad network access. Capabilities are available over the network and accessed ...

Analysis of different hypervisors

I've read some posts (see in the bottom of this post for the references) and I notice how the  hypervisor comparison and choosing criteria are still a interesting trend and not only a marketing battle between different vendors (and maybe there will be more interest will be on this aspects with the release of Windows Server 8). But in several cases the comparison is limited to the hypervisor technical characteristics (and I've already written something about Hyper-V 3.0, XenServer 6.0 and RHEV 3.0) without considering (except in some cases) that the those are only one of the possible choice criteria. One interesting ...

Issue in logging into vCenter Server using Windows AD credentials

One possible issue during an upgrade to VMware vSphere 5.1 or 5.5 (but also in a new installation) is related with the introduction of the the SSO (introduced in vSphere 5.1) component in vCenter Server that handle the authentication across the different vCenter Server components, but also against the users. In some cases you may have the following issues during the user autentication: You can log into vCenter Server 5.1 or 5.5 with the vSphere Client or vSphere Web Client only with local users Logging into vCenter Server 5.1 or 5.5 using the vSphere Client with an Active Directory domain account and/or selecting ...

Virtual CPU and Virtual Cores

In a physical environment usually the term CPU is used to refer to the physical package (or socket). The real processing unit inside this package are called cores (and not that each core can have inside more ALU and can be seen as more logical cores with hyper-threading feature). More CPU usually define a SMP system, more cores a multi-core CPU, more CPU each with more cores a complex system (usually the NUMA architecture is used in this case). In a virtual enviroment the term vCPU is used to refer to a core assigned to a VM. More vCPU define a ...

VMware exams and related products version

As discussed, all the VMware exams have a release version that depend only by the major number of the related products (or suite). And usually are all agnostic on the minor number. But the only way to be sure is check the related blueprint and verify the content (a simple and fast way could be check the document links). But there are also some specific notes depending by the certification path. Datacenter path As written in a previous post, the VCP5-DV has some difference (in the blueprint), but is still completely vSphere 5.x agnostic! Actually (when I took the exam) the VCAP5-DCA lab is ...

Microsoft Virtual Labs

Some months ago I've write about the VMware Hands on Labs and how labs are important for testing and learning about a product (also for other vendor). Events like VMworld, Microsoft TechEd, Dell Storage Forum, HP Discover, ... are a good moment to have access at those kind of labs. But of course you can also build your own labs (as described in this post) but this require more effort. A good work-around is use on-line and on-demand lab. For VMware the on-line version is just in beta, but for Microsoft this kind of tools are a reality from several years ...

Using PCoIP on WAN connections

In a View environment the PCoIP is usually the right choice and on a LAN works really well (see also the previous post about PCoIP and RDP differences). But on a wide-area networks (WANs)you have to consider some aspects to have a reasonable reactivity or to maximize the number of remote clients: you must consider bandwidth constraints and latency issues. The PCoIP display protocol provided by VMware adapts to varying latency and bandwidth conditions, but some optimization may be needed. The best reference document is the VMware View 5 PCoIP Network Optimization Guide with a lot of useful information.  But there ...

Migrating EqualLogic replicas

In the previous post I've describe how migrate volumes across two (or more) EqualLogic in the same group, using different storage pools. In the same way is also possible migrate the data on the disaster recovery site: in this case data are the remote volume replicas that are stored in a single container called delegated space. Each destination of a (asynchronous) replication must have a proper delegated space (and only one!), and a delegated space can be stored on a single storage pool. In this way, by choosing a new storage pool for a delegated space you can start the moving of all ...

Recovering a lost partition table with a VMFS datastore

There are different reason where you can you loose or corrupt your partition table of your VMFS volumes: resignature from another system (for example the backup server, if connected in SAN mode), a human mistake (datastore / delete), or maybe some storage issues. In this case usually the VMFS partition is still there and also the related data: you have "only" to rebuild the right partition table. But this could really simple if you follow the recommended practice to have only one VMFS partition on each disk. In this case you have only to build the configuration for a single partition ...

Hyper-V 2012R2 vs. vSphere 5.5

Now that both Microsoft and VMware have officially announced the new released of their virtualization products it's possible make an homogenous comparison between Hyper-V 2012 R2 (the fourth generation of Hyper-V) and vSphere 5.5. VMware vSphere 5.5 introduces several news and scalability improvements, on the other side Microsoft Hyper-V 2012 R2 consolidate its features and improve what was already existing in the 2012 version, with a limited (but significant) new features. For example now, finally, some VMware old date features are mainstream also in Hyper-V, like VM hot cloning, hot disk resize (in this case also with the possibility to reduce ...

Atlantis-Logo

I’ve already write about Atlantis ILIO USX in some previous posts (for example look at the one related to Virtualization Field Day 3). Their solution is a in-memory software-defined storage solution that pools existing SAN, NAS and DAS from across the datacenter and then optimizes how server applications and VMs consume this storage.

Now Atlantis Computing has announced the new version 2.0 of this product with the promise to enable enterprises to deliver better than flash performance, for half the cost of traditional SAN.

With USX they are jumping in the storage world making their ILIO solutions more than an storage acceleration product, but also a full software-defined storage that can work also as a storage virtualization.

VCDX-DCV

In the past days a new bunch of VCDXs (around 30) are appear, but the interesting news is that they are (or at least most of them) VCDX-NV: the new track specific for Network Virtualization (that mean mainly VMware NSX).

Seems that they are all coming from the NSX Ninja program and most of them where already Cisco CCIE (matching the criteria described on the VCDX-NV official web page). This also may confirm that there isn’t a real VCAP level for the NX path (as already commented in a previous post and also supposed in this post).

VirtualDesignMaster

Virtual Design Master is a great initiative by Eric Wright (@discoposse), Angelo Luciani (@angeloluciani) and Melissa Palmer (@vmiss33) with the original idea to build an “IT reality” build around a team competitors with a design challenge that puts their knowledge to the test, requiring many skills and disciplines from the virtualization industry.

Is something really interesting that demonstrate the power of the communities effort and is complementary with other community activities like #vBrownbags or study groups.

Also if you are not directly involved with the competition is a great opportunity to learn from other projects (check the design documents on the official web site).
