Dell’s networking portfolio was historically made by a Dell PowerConnect series for the switches in the SMB and mid-size target and the PowerConnect-W for the wireless offer. Some years ago there was also a PowerConnect-J series with the (temporally) partnership with Juniper (before the Force10 acquisition). The Dell Force10 was positioned in the top of the networking offer with several products both for the traditional networking approach (core, aggregation and access) and also for the emerging model (leaf-spine). But recently the entire networking family has been re-organized and renamed with new names, a clear positioning […]

Dell has just announced the new generation of PowerEdge servers: the Dell PowerEdge 13th generation server portfolio features customer-inspired engineering built to optimize price performance for the widest range of web, enterprise and hyperscale applications, and features state-of-the-art advancements in storage, processing and memory technology coupled with industry leading systems management capabilities. The first wave of the new Dell PowerEdge servers includes the PowerEdge R730xd, R730, and R630 rack servers, the M630 blade server, and the T630 tower server, which are built with the latest Intel Xeon E5-2600v3 processors. Combined with Dell’s end-to-end portfolio of […]

Nutanix does not need presentation: it’s one the first example of hyper-converged storage architecture and probably one of the most know (for an overview see this post). Dell also does not need any presentation and their storage portfolio has some interesting products, included PowerVault MD (based on NetApp technologies), other PowerVault products, EqualLogic and Compellent solutions. This week Dell announced is new partnership with Nutanix to provide a new series of their converged appliance built on Dell servers and powered by the Nutanix software extending Dell’s SDS portfolio. This is another step for Dell into […]

If you use SSD disks connected to a RAID controller like the Dell PERC (common in most Dell PowerEdge server), is common that the disks may be not recognized as SSD on the upper level. Because this type of RAID card cannot have a pass-thought feature (or VSAN friendly in VMware world) and is threated as a common virtual disk. If the purpose is just add the SSD as a cache system, you can use the integrated (in most recentrly PERC) feature: CacheCade is used to improve random read performance of the Hard Disk Drive (HDD) […]

Heartbleed is a software bug in the open-source cryptography library OpenSSL, which allows an attacker to read the memory of a server or a client, allowing (with special forget packets) reading (small) portition of the victim client. This could expose to lost of some data and potentially also confidendial data. Heartbleed.com has a detailed explanation of the issue, which is related to the “heartbeat” section of OpenSSL’s transport layer security (TSL) protocols and has been in the wild since March 2012 and affect all version from OpenSSL 1.0.1 through 1.0.1f. You need to upgrade the […]

In the night (in my timezone) between March 17th and 18th I’ve received an email with this subject: Congratulations, you have been selected as 2014 Dell TechCenter Rockstar! The content of the mail explain the program and the criteria: The Dell TechCenter (DTC) Rockstar program recognizes independent experts and enthusiasts for their significant positive impact on Dell TechCenter, blogs and social media when discussing Dell. After careful review of numerous applicants and nominations, we think you would be a great fit for our exclusive group.

Some years ago, I’ve write some posts on how install Dell OpenManage on VMware ESXi. The OpenManage Server Administrator (OMSA) is a Dell tool really useful for a central management or to be integrated in other Dell’s management tools. There are different options, but basically the most used ways are: Use the Dell ESXi custom image that already include also a version of OMSA (not necessary the latest) Use the command line Use VMware Update Manager The last option is my preferred option because is really faster and simplest.

In the previous post we have described how the command line of a Dell PowerVault storage allows several more operations compare the graphical interface. For example, the disk initialization is just one of the several troubleshooting cases where it becomes mandatory to rely on the command line (or on technical support). Another case is where the RAID of a disks group go into the “corrupted” state: at that point, again, there is no simple solution because you have limited options in the graphical interface. Again, the solution is switch to the command line and use the […]

One of the advantages of Dell PowerVault storage, with the MDxxx series, is that they use disks with identical bays of the server version (obviously depending on the generation, there will bays like the G9 servers or  bays with the same G10, G11, G12 servers form factor). In addition, disks are theoretically interchangeable because are the same models (almost from Seagate vendor, ad least for spinning disks). However, in practice, this was true with MD30xx models and derivatives, but with the recent series (MD32xx or MD36xx), there are some limitation based on the firmware version […]

Dell Enterprise Forum (DellEntForum) is the new name of the event previously named Dell Storage Forum. Worldwide there were already some events with this new name, but only on 2014 there will be the first EMEA event (properly this should be the third Dell’s EMEA event, after London and Paris Storage Forums): EMEA event: 14-17 April 2014 | Frankfurt, Germany

Some months ago I described the characteristics of a new Dell’s product, intended to redefine the existing server form factors and the server converged concept: Dell PowerEdge VRTX is the first and so far only Dell product (at present there aren’t similar solutions for other vendors) to merge together three different form factors (tower, rack and blade) into one with unique characteristics. It could be defined a Data Center in a box, or (using a quote from Dell) a (private) Cloud in a box. Basically it’s an integrated tower format system (complete with wheels if […]
