The dark side of converged storage networks

26 Novembre 2017

Reading Time: 14 minutes

This is an article realized for StarWind blog and focused on the design and implementation of a ROBO infrastructure. See also the original post.

Introduction

The fabric of SAN (means Storage Area Network) with Fibre Channel solutions have always been a dedicated network, with dedicated components (like FC switches).

But, starting with iSCSI and FCoE protocols, the storage fabric could now be shared with the traditional network infrastructure, because at least level 1 and 2 have a common Ethernet layer (for iSCSI also layer 3 and 4 are the same of TCP/IP networks).

In response to issues identified by external researchers, Intel has performed an in-depth comprehensive security review of our Intel® Management Engine (ME), Intel® Server Platform Services (SPS), and Intel® Trusted Execution Engine (TXE) with the objective of enhancing firmware resilience.

As a result on 20th Nov 2017, Intel has identified security vulnerabilities that could potentially place impacted platforms at risk.

VMware vSphere su Microsoft Azure

Microsoft ufficializza un nuovo servizio (al momento in preview) su Azure che risponde al binomio VMware e Amazon (relativo all’offerta VMware Cloud on AWS).

La soluzione si chiama VMware in Azure, e si tratta di un ambiente vSphere installato bare-metal all’interno dei datacenter Azure. Non ci sono dettagli architetturali, come ad esempio il numero di host minimi (su VMware Cloud on AWS è 4), il tipo di storage utilizzato (si utilizzerà la Cloud Foundation e quindi vSAN?). L’unica certezza è che l’intero servizio è implementato tramite partner VMware e non direttamente tramite VMware.

Finally, one year after Broadcom announced the intention acquire Brocade the deal is completed: Broadcom Limited announced that it has completed its acquisition of Brocade. With the close of this transaction, Brocade’s storage area networking (SAN) business is now a highly strategic part of Broadcom’s enterprise storage portfolio.

This is also an important milestone toward Broadcom completing the proposed divestiture of Brocade’s Ruckus Wired (ICX) and Wireless business to ARRIS International PLC (“ARRIS”). ARRIS has stated that it expects to close its acquisition once final regulatory approvals are complete.

KVM continua a crescere

Reading Time: 3 minutes

Nell’ambito della virtualizzazione server, i principali hypervisor di tipo 1 (o bare-metal) sono: VMware ESXi, Microsoft Hyper-V, e, per il mondo Linux, Xen e KVM.

Per quanto riguarda il public cloud, in particolare i servizi di tipo IaaS, al momento i più usati sono Xen (poiché AWS ne utilizza una versione customizzata) e Hyper-V (visto che è alla base di Azure). Cambia tutto nell’e infrastrutture on-prem poché ESXi (e vSphere) rimane la soluzione più utilizzata, con Hyper-V e KVM che seguono, ma ancora da lontano.

Notare che sia Xen che KVM rappresentano in realtà una famiglia (o una tecnologia), non un prodotto specifico: ogni distribuzione o ogni vendor ha la sua “versione” do uno o dell’altro. Se invece parliamo di XenServer allora ci si riferisce al prodotto specifico di Citrix basato su Xen (Citrix aveva acquitato il brand Xen commerciale tanti anni fa), oppure se parliamo di RHEV allora ci si riferisce all’implementazione di RedHat basata su KVM (RedHat è stata tra le prime a “sponsorizzare” KVM a discapito di Xen).
