Meltdown & Spectre: What about Microsoft Exchange?

On January 18, 2018, Microsoft has published KB4074871 which has the title “Exchange Server guidance to protect against speculative execution side-channel vulnerabilities”. As you might guess, Exchange is affected by Meltdown & Spectre – like any other software. Microsoft explains in KB4074871:

Because these are hardware-level attacks that target x64-based and x86-based processor systems, all supported versions of Microsoft Exchange Server are affected by this issue.

Like Citrix, Microsoft does not offer any updates to address this issue, because there is nothing to fix in Microsoft Exchange. Instead of this, Microsoft recommends to run the lates Exchange Server cumulative update and any required security updates. On top, Microsoft recommends to check software before it is deployed into production. If Exchange is running in a VM, Microsoft recommends to follow the instructions offered by the cloud or hypervisor vendor. read more

My tool chain for 2018

Rainer Sturm/ pixelio.de

Each of us has his or her personal tool chain. Depending on your job role, the tool chain will look different. My personal tool chain does not have changed much over the last few years, but if I added or removed a tool to my tool chain, this change was often influenced by other peoples tool chain.

My primary work device is a Lenovo ThinkPad X250 (Intel i5 5200U, 8 GB RAM, 250 GB SSD) with Windows 10. I’ve added a 6 cell battery, so I have ~ 95 Wh of battery capacity. This gives me ~ 16h of battery lifetime with my common workload. The 12,5″ screen seems to be small, but it’s okay as I have two 24″ displays at the office. It’s small, lightweight, long battery life and powerful. I awaited the new Lenovo Thinkpads, that were presented some day ago on the CES. But Lenovo removed the Ethernet port on the X280. So this is not longer an option. Maybe the T480 with an additional 72 Wh battery… Devices and accessories are safely stowed in an Eastpack Floid Ash Blend2. It’s a great backpack, light and not too big. read more

HPE Data Protector 9.08 is available

3 days ago, on 13th October 2016, HPE has released patch bundle 9,08 for Data Protector 9. A patch bundle isn’t a directly installable version, instead it’s a bundle of patches and enhancements for a specific version of Data Protector, in this case Data Protector 9.

Beside fixes for discovered problems, a patch bundle includes also enhancements. There are some enhancements in this patch bundle, that have caught my attention particularly.

QCCR2A64053: Support for object copy of file system data to Microsoft Azure. Data Protector now supports the creation of a special backup device, which can be used together with Data Protector object copies, to copy Data Protector file system backups to Azure Backup Vaults. This is an easy way to create copies of important data on Microsoft Azure. read more

Get progress of ‘Shrink Database’ task on a Microsoft SQL Server

Shrinking a big database on a Microsoft SQL Server can take some time. And it’s one of those tasks, where you wont get a status until it’s finished. I really hate this… But this small T-SQL query can help:

Simply open a new query windows, paste the query into the query windows and execute the query. The query outputs the progress in percent and the estimated completion time.

PowerShell ISE on steroids

I’m not a developer. I deal mainly with infrastructe, things like virtualization, storage & backup, networking etc. Sometimes I had to write scripts, primarily PowerShell, batch or Bash. Many years back, I also wrote Csh and Ksh scripts. In the past years, automation was one of the rising trends in the infrastructure segment. And with automation, new challenges came up. Today I have to work with Windows PowerShell, in case of VMware with PowerCLI (which bases on Windows PowerShell), and sometimes I have use with REST APIs. I’m still not a developer. Due to this fact, I need tools that help me getting my work done. read more

Reset the HP iLO Administrator password with hponcfg on ESXi

Sometimes you need to reset the ILO Administrator password. Sure, you can reboot the server, press F8 and then reset the Administrator password. If you have installed a HP customized ESXi image, then there is a much better way to reset the password: HPONCFG.

Check the /opt/hp/tools directory. You will find a binary called hponcfg.

All you need is a simple XML file. You can use the VI editor or you can copy the necessary file with WinSCP to the root home directory on your ESXi host. I prefer VI. read more

Using HP StoreOnce as target for Windows Server Backup (WSB)

Some days ago, I blogged about the new HP StoreOnce software release 3.13.0. This release included several fixes. One fix wasn’t mentioned by me, although it’s interesting.

  • Fixed issue where Windows 2012 R2 built-in native backup was not supported with 3.12.x software (BZ 61232)

Windows Server Backup (WSB) is part of Windows Server since Windows Server 2008. WSB can create bare metal backups and recover those backups. The same applies to system state backups, file level backups, Hyper-V VMs, Exchange etc. Very handy for small environmens. Backup can be stored on disk or on a file share. With Server 2012, the file share must be SMB3 capable. So if it’s not a Windows file server, the NAS that offers the file share has to be SMB3 capable. This doesn’t apply to Windows Server 2008 (R2). read more

PernixData Architect Software

With the general availability of PernixData FVP 3.1, PernixData released the first version of PernixData Architect.

One of the biggest problems today is, that management tools are often focused on deployment and monitoring of applications or infrastructure. This doesn’t lead to a holistic view over applications and related data center infrastructure. You have to monitor at several points within the application stack and even then, you won’t get a holistic view. Without proper information, you can’t make proper decisions. At this point, PernixData Architect comes into play. read more

Outlook license requirements for Exchange features

Microsoft Exchange Server licensing is rather simple. You can choose between two Exchange licenses:

  • Standard (up to 5 mailbox databases)
  • Enterprise (up to 100 mailbox databases)

Standard and Enterprise only differ in the number of supported databases! Feedl free to use Exchange DAG with Exchange Standard and Windows Server Standard! To license your clients, you have to purchase a Client Access License (CAL) for each user or device that accesses your Exchange server environment. There are two types of CALs:

  • Standard
  • Enterprise (add-on for Standard CAL)

The Standard CAL is always necessary and enables most features of Exchange. The Enterprise CAL is an add-on license. If a user needs one of the Enterprise CAL features, you have to purchase a Standard AND an Enterprise CAL. The Enterprise CAL enables the following features: read more

DataCore mirrored virtual disks full recovery fails repeatedly

virtual_disk_error_ds10_mirror

Last sunday a customer suffered a power outage for a few hours. Unfortunately the DataCore Storage Server in the affected datacenter weren’t shutdown and therefore it crashed. After the power was back, the Storage Server was started and the recoveries for the mirrored virtual disks started. Hours later, three mirrored virtual disks were still running full recoveries and the recovery for each of them failed repeatedly.

The recovery ran until a specific point, failed and started again. When the recovery failed, several events were logged on the Storage Server in the other datacenter (the Storage Server that wasn’t affected from the power outage): read more
